Will the real Tanager please raise its wings!

2/8/2026

Yes, it is the Bananaquit, a member of the Tanager family! (With apologies to "To Tell the Truth").

This is my 4th blog post from our recent trip to Costa Rica, and this post is devoted to one avian family, the Tanager, or Thraupidae, in the order Passeriformes (songbirds).

​Tanagers reside in the Neotropics, from southern Mexico to the tip of South America. The International Ornithological Committee (IOC) recognizes 392 tanager species, distributed among 107 genera. Confusingly, only 149 of these species, less than half, are called "tanager". Another 108 are called "finch", with the rest having names including banaquit, honeycreeper, dacnis, saltator, bullfinch, seedeater, hemispingus, conebill, flowerpiercer and yellow cardinal! 

To make matters worse, of the four "tanagers" living in the U.S. (i.e., Summer, Scarlet, Western and Hepatic) none of them are in the Tanager family - they are all in the Cardinal family!  Ohhh boy! 

Below is a family tree of the "True Tanagers".  All the species that are in the tanager family are on the far left of the frame. To the right, in the blue box, are species that were in the tanager family, but because of genetic analysis have now been moved out. To the left of center is the Fringillidae family, with two genera that together hold 35 species of euphonia and cholophonia. On the right are three genera of the Cardinal family that hold all the "tanagers" that we see in the U.S. plus others that are in the neotropics. (Ref: Content for the family tree from Wikipedia, Tanager.)

The upshot? True Tanagers are neotropical birds living well south of us, with a lot of them in, you guessed it, Costa Rica.  So let's see what true tanagers look like, along with a review of the four species with tanager in the name that we enjoy north of the Rio Grande.

Warning, there are 19 species in this post! Top up your coffee and let's go! 

Picture
An abbreviated Tanager Family Tree, showing to the right in the blue box those species moved to other families for genetic reasons, but often retaining "tanager" in their names.

Let's start with birds in the Tanager family (Thraupidae).

Crimson-collared Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/500sec., f/7.1, ISO 16000.

The Crimson-collared Tanager is a strikingly beautiful bird with bold black and red markings and a pale bill. The male and female are identical in appearance. They live in humid lowland forests. These images were captured in the rain forest at Selva Verde Lodge early on the morning of November 3rd. Crimson-collared Tanagers eat fruit and insects. Here they are feeding on bananas put out with the feeders. 
Picture

Picture
Canon R5 MkII, RF 100-500mm at 400mm, 1/250sec., f/7.1, ISO 10000.

Above, presumably an immature bird has gathered banana fruit, but rather than eat it, passes it to an adult, perhaps mom or dad, and then waits to be fed. 

Picture

I find it intersting that the bird on the left could have eaten the banana without help, but passed it to the adult first, reinforcing their parent/offspring relationship. 

Feeding complete, the pair pose for a photo.

Scarlet-rumped Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/320sec., f/8.0, ISO 6400.

The Scarlet-rumped Tanager is a gregarious bird that lives on the Caribbean slope of Central America, eating fruit and insects. The male is black, with a scarlet rump and back.  With the black wings parted, seen above and below, we can see the red rump and back.
Picture

Blue-gray Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/200sec., f/7.1, ISO 10000.

The Blue-gray Tanager is a bird of the humid lowland neotropics, preferring semi-open habitats and frequenting forest edges along roads and rivers in plantations and urban parks and gardens. Blue-gray Tanagers eat a variety of fruit and arthropods, and were common visitors at the Selva Verde lodge feeders while we waited for breakfast. ​

Canon R5 MkII, RF 100-500mm at 363mm, 1/200sec., f/7.1, ISO 10000.

The Blue-gray Tanager has a gray head that fades to blue on the back and wings with intricate blue/green details.

Picture

Palm Tanager


Picture
Canon R5 MkII, RF 100-500mm at 300mm, 1/320sec., f/5.6, ISO 12800.

The Palm Tanager is similar to the Blue-gray Tanager, although less likely to colonize urban centers. The Palm Tanager is common at forest borders, but also inhabits the canopy of the forest interior. Their diet is balanced between fruit and arthropods. They usually travel in pairs or small groups. ​

Although the species is described as drab in appearance, the bird captured here has subtle blue and green details on the wings. 
Picture
These images were captured in the rain. The bird is visibly wet, adding texture and detail to the feathers.

Picture

Below we can see that portions of the wings are black, creating a straight line and then merging with the black tail feathers.

Plain-colored Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/800sec., f/7.1, ISO 6400.

The Plain-colored Tanager is perhaps the most drab of genus Tangara Tanagers, most of which have colorful, metallic and opalescent plumage (Ref: Birds of the World). The Plain-colored Tanager feeds on fruit and insects and is commonly found in the forest canopy, woodland edges, second growth and gallery forest, as well as shaded cacao plantations. 
Picture
Although the Plain-colored Tanager is a Costa Rican bird, these images were captured close to sea level in the Bocas del Toro region of Panama, in the Caribbean in March of 2024.

Silver-throated Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/4000sec., f/7.1, ISO 5000.

Silver-throated Tanagers are brightly colored birds of the tropical evergreen forests from the lowlands to the mountains. They eat a variety of fruits as well as some insects. Little is known about their behavior, population dynamics or demography (Ref: Birds of the World).  

These images were captured on November 6, 2025 at 7600 feet in the Talamanca cloud forest.

So far we have been looking at "true tanagers", colorful (with one exception!) birds with "tanager" in their name who are bona fide members of the tanager family.

Next, let's stick with the "true tanagers" but look at just a few of the dozens that bear names that may surprise you! 

Green Honeycreeper


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/500sec., f/7.1, ISO 8000.

Green Honeycreepers are tanagers that favor the canopy of humid lowland rainforests. These images were captured on November 3rd and 4th in the Sarapiqui rainforest, our second stop on the November 2025 trip. Green Honeycreepers eat mostly fruit, but also eat small insects and nectar. This species is widespread and common in Central and South America, yet little is known about many aspects of its natural history (Ref: Birds of the World)
Picture
Above and below are photographs of the male with a black cap and mask, decurved bill, yellow on the lower mandible, and feathers that vary from blue (above) to green (below). The male below is visibly wet.

Red-legged Honeycreeper


Picture
Canon R5 MkII, RF 100-500mm at 300mm, 1/500sec., f/6.3, ISO 10000.

Red-legged Honeycreepers eat fruit, insects and nectar. They favor flowering trees at forest edges, as well as coffee and cacao plantations. The male is a brilliant blue with a black mask, and black markings on the neck and wings. Above, two males face off showing their neck and head feathers. Below, a male perched in the Sarapiqui rainforest showing off bright blue wing markings. Males and females have bright red legs, a striking feature and an easy identifier.

Shining Honeycreeper


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/320sec., f/7.1, ISO 12800.

At first glance the Shining Honeycreeper looks like the male Red-legged, but without the blue markings on the back, and of course, with bright yellow legs! 

Shining Honeycreepers favor tropical lowland evergreen forests, typically foraging in the canopy (Ref: Birds of the World)

Bananaquit


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/2000sec., f/7.1, ISO 20000.

A tanager, really?  Yup - hey, what's in a name?

​Bananaquits live from Mexico and the Caribbean all the way south to Argentina. They sport a down-curved bill, black upperparts, a bright yellow breast and belly and a striking white eyebrow. The species has no less than 41 recognized subspecies with variations in throat color (white, gray or black), the white wing  spot, and the extent of yellow on the underparts. They eat nectar and fruit, favoring flowering trees and shrubs.

Blue Dacnis


Picture
Canon R6, RF 100-500mm at 472mm, 1/400sec., f/7.1, ISO 6400.

The Blue Dacnis is yes, another tanager, who lives in humid lowland forests from Honduras south to Argentina. The male is a stunning bright turquoise blue with black wing and tail markings, and the female is mostly green with a blue crown. They eat nectar and insects in the tops of trees. These photographs were captured in March of 2024 on an island on the Panama Caribbean coast near Bocas del Toro.
Picture
I was standing very close to the tree where this pair was foraging. We can see the birds peering up looking for insects on the underside of leaves.

Buff-throated Saltator


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/250sec., f/7.1, ISO 4000.

Well, here is a "true tanager" that used to be a cardinal!  The Buff-throated Saltator was traditionally grouped with cardinals and grosbeaks (gosh, he does look a bit like a grosbeak . . ) but recent research has moved the Buff-throated Saltator into the tanager family. 

Buff-throated Saltators favor the edges of humid lowland forests and feed mostly on fruits, some seeds and occasional ants and wasps (Ref: Birds of the World).
Picture

Picture

The sexes are similar in appearance. These images were captured in the rainforest on November 3rd. 

Picture

Well, that's it for the "true tanagers" ! 

Here come Six Cardinal Family members - all with Tanager on their name tag!  Oh boy, family reunions are getting really confusing!


Flame-colored Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/400sec., f/7.1, ISO 5000.

Flame-colored Tanagers are members of the Cardinal family who live in the highlands of Central America with occasional visits as far north as the mountains of SE Arizona. Males are orange or red with black wings with white wing bars. Females are olive above with dusky streaks and yellow below with a wing pattern similar to the male. They eat a variety of fruits and insects in the mid-story and canopy. 
Picture
The image above was captured on November 7th in the cloud forest of the Talamanca Mountains in Costa Rica at ~8,000 feet.  The images that follow below were captured in March of 2024 in Panama at ~3500 feet, near the continental divide.

Red-throated Ant-tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/250sec., f/7.1, ISO 2000.

Red-throated Ant-Tanagers live in humid regions on the Atlantic side of SE Mexico, Central America and northern Columbia. They eat fruit in large quantities as well as insects, including swarms of army ants, especially in their northern range. These images were captured on November 3rd in the rain forest of Costa Rica.
Picture
The male, shown here, is a dusky red with a bright red throat, dark face, and a red crown, seen above and below. 

Picture

Hepatic Tanager


Picture
Canon R6, RF 100-500mm at 500mm, 1/500sec., f/7.1, ISO 32000.

The Hepatic Tanager lives year round from northern Mexico all the way south to Argentina, with some migration for breeding from Mexico into Arizona, New Mexico and Texas. See the range map to the right from All About Birds. 

Males are brick red to red-orange brightest on the crown and throat, with dark lores, grayish ear coverts, flanks and back. Adult females are olive-yellow to orange-yellow on the forecrown, throat and underparts. 
​
They eat insects and fruit. 

Picture
Although Hepatic Tanagers are residents of Central and South America, all these images are from SE Arizona on their northern breeding range. The image above was captured at Cave Creek Ranch in Portal, Arizona in April of 2023 (a male in breeding plumage), and the image below from Mt. Lemmon in October of 2021. ​

Scarlet Tanagers are long range migrants, wintering in South America and breeding in the northern U.S. and Canada. The photographs shown here were all captured during their northern migration. The images above and below were taken in NW Ohio on the shore of Lake Erie in May of 2022, the third photo below was taken at High Island on the Bolivar Peninsula in SE Texas in April of 2019.  

Scarlet Tanagers eat a variety of insects during their breeding season. During migration and on their winter range they eat fruit as well as insects.

Summer Tanager


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/4000sec., f/7.1, ISO 3200.

Summer Tanagers winter from southern Mexico to South America, and breed across northern Mexico and the U.S. This species is known for eating bees and wasps on wintering and breeding grounds, as well as fruit. Males are bright rosy-red, females yellow to mustard yellow. 

The image above was captured at the Paton Center in Patagonia, AZ, in August of 2025. This is a male that appears to be molting  following breeding earlier in the summer. The image below was captured at Cave Creek Canyon in April of 2021.

If you ever wondered why Arizona birding festivals are in the heat of the summer, breeding is the reason. A number of tropical species will come north to the U.S. just for breeding, then return south.

Western Tanager


Picture
Canon R5 MkII, RF 100-500mm with 1.4x Ext at 700mm, 1/1000sec., f/10, ISO 800.

Western Tanagers winter as far south as Central America, and breed north in the western U.S. and Canada as far north as 60 degrees, where they may spend as little as two months on their breeding grounds. Although the male is strikingly bright, the species favors forest shade, generally keeping the bird out of sight. The image above was a rare sighting on the Meadow Trail on Mt Lemmon in June of 2025. Below we see a female perched on a railing in Summerhaven in June of 2013.

The Western Tanager feeds on insects during the breeding season, adding fruits and berries other times of year.

Let's finish with probably the cutest bird in this series . . . .

Yellow-throated Euphonia


Picture
Canon R5 MkII, RF 100-500mm at 500mm, 1/250sec., f/7.1, ISO 3200.

Why this species here? Well, the Yellow-throated Euphonia is another former Tanager who got reassigned, not to the Cardinal family, but to its own Family, Fringillidae, Genus Euphonia. Here we see a male with a short bill, stubby tail, bluish/black above and yellow below. The female is yellow or yellowish green. 
(Ref: Birds of the World).
Picture
These images were captured at the Nest Nature Center in the Costa Rican foothills at ~2000 feet on November 2, 2025. The Yellow-throated Euphonia eats fruit, mostly mistletoe as well as a variety of berries.

Hummingbirds of Costa Rica

1/15/2026

4 Comments

 
Picture
Fiery-throated Hummingbird, Talamanca cloud forest, Costa Rica, November 7, 2025.

For this my third post on Costa Rica I decided to tally all of the hummingbirds we saw over the two weeks in November and post them here. These species are all unique to Central America (with some overlap north into Mexico or south into South America), with one local species that will look familiar to Arizonans.

For anyone from the U.S., these are special birds. 

Our first group of three birds was spotted in the low altitude rainforest of NE Costa Rica, on the Caribbean side. We toured the area around Sarapique for several days, where the forest gets ~14 feet of rain a year! The lodge where we stayed, and the preserves we visited, all had covered walkways and platforms, keeping us and our gear dry (most of the time!).  However, there was not a lot of light! 

White-necked Jacobin


Picture
Canon R5 m2, RF 100-500mm at 254mm, 1/1000 sec.,f/6.3, ISO 12,800.

White-necked Jacobins live year round in the humid forest canopies and second growth forests of Central and South America, see the ebird range map to the right. They feed on nectar and small arthropods, and are aggressive toward other species and territorial with each other around flowers and feeders. In Costa Rica they breed from January to June.​ (Ref: Birds of the World).
Picture

Picture
Canon R5 m2, RF 100-500mm at 343mm, 1/1250 sec.,f/5.6, ISO 8000.

The White-necked Jacobin is a strikingly beautiful bird. The "white neck" is really a patch at the nape, seen in the lower bird of the pair below. Most noticable in the male is the deep blue head and neck, offset by an almost pure white belly and tail. The tail feathers have a thin dark tip, creating a framing effect on the whole bird. The female has varying color, with "typical" markings of a blue-green breast scaled with white.

They are aggressive toward one another, as the interaction below demonstrates. Note that the male at the top of the image is missing part of his secondary flight feathers on the right wing, not matched on the left, and likely due to an injury. He seems to fly well in spite of the defect.

Picture
Canon R5 m2, RF 100-500mm at 128mm, 1/2500 sec.,f/8.0, ISO 10,000.

​For the photo geeks: These hummers are denizens of the rain forest, emphasis on a forest with high canopy and lots of rain! Which means fast moving birds in very little light. Low ambient light combined with the dark blue head and neck in the male with a bright white belly and tail make it difficult to get balanced exposure. Expose for the blue neck and the whites blow out, expose for the while tail, and the neck descends into darkness and noise! 

Bronze-tailed Plumeleteer


Picture
Canon R5 m2, RF 100-500mm at 451mm, 1/1250 sec.,f/6.3, ISO 16,000.

The Bronze-tailed Plumeleteer is widespread throughout Central America and parts of Columbia. The subspecies found in Costa Rica, seen here, does not have a bronze tail, although it retains the distinctive red feet of the rest of the species.  Bronze-tailed Plumeleteers prefer the understory and middle levels of wet forest edges feeding on flowers as well as flying insects. They are aggressive around flowers and will often defend territories to protect their food sources. (Ref: Birds of the World).
Picture

Picture

Picture

The red feet are quite distinctive and a key field mark.

Rufous-tailed Hummingbird


Picture
Canon R5 m2, RF 100-500mm at 200mm, 1/800 sec.,f/6.3, ISO 12,800.

The Rufous-tailed Hummingbird is a medium sized hummingbird with a rufous-colored tail and bright pink/red bill. The Rufous-tailed feeds on nectar and small insects and is highly territorial over feeding sites. It prefers the lower understory and is one of the most common hummers at gardens and cultivated areas at the forest edge, from Mexico to Columbia. See the range map to the right. (Ref: Birds of the World).
Picture

Picture

The rufous tail itself has dark tips. Unlike the Bronze-tailed Plumeleteer, its feet are dark. 

Picture

Picture

Picture
Canon R5 m2, RF 100-500mm at 167mm, 1/2000 sec.,f/13, ISO 16,000.

The next six species were spotted in the Talamanca Mountains, just over the continental divide on the Pacific side of Costa Rica. This area is high cloud forest, still wet, but cooler, with mixed clouds. 

White-throated Mountain Gem


Picture
Canon R5 m2, RF 100-500mm at 500mm, 1/1000 sec.,f/7.1, ISO 8000.

​The White-throated Mountain-gem is endemic to the mountains of Costa Rica and Panama. Within this small range there are two subspecies, one in Costa Rica and one in Panama. The male Costa Rican L.c. cinereicauda, seen here, has a gray tail, whereas the male nominate of western Panama has a dark green tail with a bluish-black subterminal band. (Ref: Birds of the World).
Picture
The White-throated Mountain-gem frequently forages in the canopy but nests in the understory. They are territorial at flowers and dominant over the Lesser Violetear, but subordinate to the Fiery-throated Hummingbird. ​

An aside on feather colors: The color of a bird's feather is produced in two very different ways, either as the result of pigments (red/yellow or black/gray to brown/buff) or as the result of the nanostructure of the feather surface. The structural color is produced by the interaction of  incident light waves with the feather surface which reflect only certain colors back toward the viewer. The brilliant jewel like colors we see in hummingbirds is produced by the surface structure. Some of these colors are very directional, as in the throat of our next hummer, the Fiery-throated (Ref: David Allen Sibley, What It's Like to be a Bird, Knopf, New York, 2020, p. xi-xii).


​Fiery-throated Hummingbird


Picture
Canon R5 m2, RF 100-500mm at 472mm, 1/250 sec.,f/7.1, ISO 10,000.

The Fiery-throated Hummingbird lives in the cloud forests of Costa Rica and Panama, defending patches of flowers and generally showing dominance over other hummingbird species in its range. 

The Fiery-throated is covered with a mixture of blue, green, and yellow feathers, with a dark throat patch that turns brilliant red at the correct angle, due to the feather surface structure,  hence the bird's name, Fiery-throated. (Ref: Birds of the World).
Picture
The throat color in the images above and below is most likely pigment based, in the brown to buff range. At the correct angle the nanostructural components that overlie the pigment become dominant, and the throat turns red.

Picture

In the series above and below, a Fiery-throated at a flower. As the bird drops down and turns his head, the angle of the throat to the light changes, adding a flash of color.

Picture

The flashes of color occur very quickly and don't last long.

Lesser Violetear


Picture
Canon R5 m2, RF 100-500mm at 343mm, 1/1000 sec.,f/7.1, ISO 12,800.

The Lesser Violetear lives in mountain forests from Costa Rica to Boliva. See the ebird map to the right.  

The Lesser Violetear is glittering green overall with a patch of violet feathers on the sides of the head, hench the name "violet tear."   Their overall color varies with the light, with a fascinating feather coloration on the throat that at certain angles looks like a knitted sweater.

The Purple-throated Mountain Gem sports iridescent green contour feathers with a white stripe behind the eye. The female (shown here) has pale rufous underparts. The male is primarily green with a purple gorget. They live in the cloud forests of Nicaragua, Costa Rica and Panama, feeding on nectar supplemented with insects.

Volcano Hummingbird


Picture
Canon R5 m2, RF 100-500mm at 500mm, 1/1000 sec.,f/7.1, ISO 51,200.

The Volcano Hummingbird is among the smallest birds in the world, weighing in at 2-3 grams. Its Spanish name is Chispita, meaning "little spark." Above is a male with a brilliant purple gorget that varies from shades of purple to red depending on the subspecies. Below and following is a female with dark spotting on the throat. The Volcano lives in the highlands of Costa Rica and Panama, above ~6000 feet. (Ref: Birds of the World).
Picture
The bird's small size and small bill limits its feeding to small flowers that are not attracted to larger species. Birds of the World reports this species will visit ~2,700 flowers a day to meet its metabolic needs. 
For the bird and photo geeks: The male captured above is feeding at small garden flowers typical for the species and its small size. The female below was
photographed at at an excellent cafe and preserve where the highly attentive staff had picked flowers and hung them on the upper deck to attract the birds. As the nectar would deplete, the staff would spray the flowers with more sugar-water. The female Volcano below is feeding off of a large flower in large part because it was dripping with sugar!

Talamanca Hummingbird


Picture
Canon R5 m2, RF 100-500mm at 324mm, 1/1000 sec.,f/6.3, ISO 2000.

If this bird looks familiar to birders in SE Arizona, it is for a good reason. In 2017 the Magnificent Hummingbird, who lived in a range from Colorado, New Mexico and Arizona down to Costa Rica was split into two separate species, the Rivoli's to the north, (including Mt. Lemmon), and the Talamanca to the south, in the mountains of the same name in Costa Rica and western Panama. 
Picture
On this trip It was fun to see and photograph the Talamanca, which before November, I knew only as a footnote to the sad story of a local hummingbird losing a Magnificent name.

Picture

The Talamanca is a large hummingbird. Compare the size of the Talamana to the flower in the image above and below on the left, with the size of the Volcano below on the right. The Volcano is about the size of the flower, the Talamanca is much larger.
Picture
Picture

Picture
Canon R5 m2, RF 100-500mm at 324mm, 1/2500 sec.,f/6.3, ISO 4000.

The Talamanca's throat and crest vary in color with the angle of the light. Again, the result of structural color.

Picture
Canon R5 m2, RF 100-500mm at 238mm, 1/2500 sec., f/7.1, ISO 6400.

The color variation becomes more obvious in the sequence that follows where within a fraction of a second the bird turns his head and the color disappears then reappears. Now you see it, now you don't!

Picture

Picture

For completeness, below is an image of a Rivoli's Hummingbird, the Talamanca's near relative, photographed at the Southwestern Research Station in the Chiricahua Mountains of Arizona in April of 2023. As noted earlier, until 2017 the Talamanca and the Rivoli's were one species, the Magnificent. 

Picture
To the right is a ebird range map for the Rivoli's.

And finally, from the foothills of Costa Rica, a hummer even larger that the Talamanca, the largest of the hummers in Costa Rica the . . . .

Violet Sabrewing


Picture
Canon R5 m2, RF 100-500mm at 500mm, 1/400 sec., f/7.1, ISO 8000.

The Violet Sabrewing lives in mountain forests from southern Mexico south to western Panama, frequenting second growth forests, forest edges, banana plantations and flower gardens. These photographs were captured at the Nest Nature Center in Costa Rica, which is in the foothills at ~1600 feet. 

Picture

Picture

The bird is named for its large sabre shaped primary flight feathers, quite prominent in the sitting position, seen here. The body feathers are a deep violet with hints of green. The bill is curved down slightly toward the tip (decurved).

Picture

The tips of the tail feathers are white.  The birds length is 13-15 cm or 5-6 inches.  (Ref: Birds of the World).

Picture


In Closing . . . . . .

There are over 360 hummingbird species on this planet, all living in the western hemisphere, also known as the Americas.

Of this 360, about 50% live in the equatorial belt, from +10 degrees North (Costa Rica) to -10 degrees south (Brazil) latitude. About 50-54 species live in Costa Rica, making it a hummer hot spot with great places to visit and wonderful people to meet. So venture south for a visit, beef up your life-list, and get some great photographs!  In this post we have seen only 10 species, but all of them a lot of fun! Next time I visit, I will have 44 more species to discover!

That's all for now!  More coming soon.
​Happy trails!

Immature male Anhinga drying his feathers, October 31, 2025.

My first post on Costa Rica was on November 20th, on the Resplendent Quetzal, titled Just in from Costa Rica: The Resplendent Quetzal!  This post is on Cano Negro, a preserve at the far northern reaches of Costa Rica in low wetlands very close to the border with Nicaragua.  See the map of Costa Rica to the right, with the red pin at Cano Negro.
Picture
Here one finds abundant rivers and wetlands that drain north over the border into Lake Nicaragua (Cocibolca or La Mar Dulce), the largest lake in Central America. This is a prime spot to see some of the special water birds of Central America. Let's go!​

Sungrebe


Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/5000 sec., f/7.1, ISO 5000.

Sungrebes are very interesting birds.*

First, they are not grebes, but finfoots, genetically closer to rails than to grebes. They are in the order Guiformes, family Heliornithidae, consisting of only three species, the African Finfoot, the Masked Finfoot (Asian, and endangered) and the Sungrebe, native to Central and South America, range map to the right.
Picture
The finfoots are likely of Old World origin, with movement into the Americas via land bridges (Beringia) explaining the Sun Grebe's presence oceans away from its two closest finfoot cousins.  (Ref: Wikipedia). 

​And, they hate the
​ sun! So much for naming conventions! **

*Almost all of my blog references on U.S. birds refer to All About Birds, a Cornell website that is free to users in the U.S.  However, birds that are not seen within U.S. borders are not in All About Birds, but are covered in detail in the academically oriented Birds of the World,  another Cornell website, which requires a subscription. My references in this blog are mixed. I have tried to refer to free websites, but when detail is required, I do refer to Birds of the World. 

**The name in fact comes from the its scientific genus Helionis, (Greek Helios, sun, and Ornis, bird), combined with grebe, because of their lobed feet, similar to grebes. 

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/1000 sec., f/7.1, ISO 5000.

Sungrebes are similar in appearance to rails, with long slender bills and lobed toes. They are secretive, living on quiet streams among thick vegetation, making them hard to study. Birds of the World begins its Sungrebe section on Diet and foraging with the words, "Little information."  However, studies from 1968, 1989, and 1993, report a diet of snails, insects, spiders, small frogs, lizards and small crabs. Unlike grebes, they are infrequent divers. 

I feel fortunate to have captured these images on October 31st. 

Picture

Sungrebes ride low in the water, with black and white striped necks. Females have a rufous patch on the side of the face. The bird we see here is likely a male, sans patch.

Picture

Like many birds, the back of the head and neck of this male could be mistaken for the front of the head, perhaps making a predator think twice before striking. 

Picture

Picture

Sungrebes nest in vegetation directly over the water, about a meter above the surface. The female lays 2 to 4 eggs,  hatching after 10-11 days of incubation, the young emerging almost naked and very dependent (altrical*).

The male is unique among world species for having a specialized skin pocket under the wing  (basically in the bird's "armpit") where the young can be carried even during swimming and flying. As the chicks grow, they may move to the dad's back, where they can ride even in dives.   (Ref: Alvarez del Toro 1971, cited in Birds of the World Sungrebe. )

*Altrical refers to chicks that are born dependent, with minimal feathers and no ability to navigate or feed independently. These chicks are generally nest bound, and fed by their parents. Examples include most songbirds like the American Robin, and raptors like owls and hawks.  Precocial chicks are born feathered and ready to go, with eggs hatching all at one time. Examples include Gambel's Quail, and Wood Ducks. 

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/1200 sec., f/7.1, ISO 5000.

The only good research on the Sungrebe's "pit pocket" was done by Alvarez del Toto in 1971 (Ref: "On the biology of the American finfoot in southern Mexico." The Living Bird, Vol. 10, pp. 79–88). There are few drawings of the pocket itself, and fewer photographs, however it is reported that the male has an extra set of feathers at the base of the wing that helps to create a seal on the pocket. 

In the image of the male Sungrebe below, there seems to be an extra or at least a thicker set of underwing coverts at the base of the wing that might demarcate the pocket. 

Picture

Sungrebes in Costa Rica are reported as breeding at the beginning of the rainy season, about April, so by November when we were in Costa Rica the fledglings have likely matured beyond dependency on the parents.
In the series that follows we see a male working hard to take off!  He is "running" on the water in short hops, leaving a long series of splash marks behind. 

Picture

Picture

Picture

Picture

As he gets in the air, his black and yellow lobed feet appear. Lobed toes can be brought together in the water to simulate webbed feet for swimming.

Picture

Picture

Above and below, images of the male Sungrebe just getting airborne, with his snazzy black and yellow lobed toes in evidence.

Picture

Picture

Picture

Of the ~11,000 species of birds on this planet, the male Sungrebe is the only one known to have a specialized underwing pocket for carrying the young. 

Anhinga


Picture
Canon 7D Mkii,  EF100-400mm with 1.4x III at 560 mm, 1/400 sec., f/8/0, ISO 250, +0.67 EV.

Anhingas (the species) are members of the family Anhingidae, one of four families in the Order Suliformes, which includes frigatebirds, boobies, gannets, and cormorants. Note that the word "Anhinga" designates both the species described here as well as the genus it belongs to, which includes three other species, the African Darter, Oriental Darter, and the Australasian Darter. 

​Anhingas, like cormorants, swim and dive to catch fish, and like cormorants have feathers that do not repel water, making diving easier, but requiring time out of water to air dry before they can fly.  
Picture
Anhingas live year round close to water, fresh or salt, from the southeast U.S., into Mexico, Central and South America. See the range map above.

The male Anhinga has a black neck and body, with white patterns on the wings, and orange to red sprinkled on the head. The male seen in the images above and below was seen at Brazos Bend State Park in Texas in the spring of 2019.

Picture

Now, back to Costa Rica.  

The Anhingas shown below were all seen in the Cano Negro area on October 31st. The buff colored necks are typical of immature males or females and in the breeding season the male will sport turquoise blue markings around the eye, seen in the two images below. In Costa Rica Anhingas will breed when resources are plentiful, usually at the end of the dry season, March-April. My conclusion (possibly wrong!) is that this is a male at the end of breeding season that still has neck coloration of an immature. Or, perhaps there are subspecies color differences in this area of Costa Rica.  If anyone has the answer, please let us all know in the comments section at the end of this post.

Above and below, this immature male Anhinga is perched on a snag drying out his feathers.

Below the Anhinga feet are evident,  fully webbed, with a nail at the end of the toe to facilitate perching.

Anhingas are excellent swimmers, using their bill to spear fish.

Northern Jacana


Picture
Canon R6 with RF 100-500mm at 500mm, 1/2500 sec., f/7.1, ISO 1600, +1.33 EV.

The Northern Jacana is in the order Charadriiformes, a large and diverse order known by the collective name "shorebirds", which includes plovers, oystercatchers, stilts, avocets, sandpipers, gulls, terns, skimmers, and jacanas! They are known for their long toes allowing them to walk on surface vegetation. This gives the appearance of walking on water, leading to the nickname "Jesus bird." 
Picture
Northern Jacanas feed on insects from emergent vegetation, as well as some fruit. As the range map above shows, they live in southern Mexico, the Caribbean, and Central America, always on or near water. They are spotted rarely in the southern U.S. One Northern Jacana took up residence in Tucson in December 2020 under the Ina Street bridge. For more on this see my post from 2020: A rare visitor down under the Ina Street bridge . . . . 

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/2000 sec., f/7.1, ISO 8000.

Male and female jacanas look alike, although the female is larger. Here we see a male looking after his brood. Northern Jacanas may breed year round if enough water is present.

Northern Jacanas have a polyandrous breeding system, whereby a female lives in a territory that covers the territories of 1-4 males. The males build multiple nests in their area, and the female mates with multiple males, laying eggs in sequence in the male's nests. The male incubates the eggs and cares for the hatchlings, which unlike Sungrebes are precocious, born able to swim, dive and feed.  (Ref: Wikipedia)

Here we see a male with three chicks feeding in the marsh.

Picture

Picture

Picture

Northern Jacanas have very long toes, even as chicks. Above and below we see the brood walking on the growth in the marsh looking for food.  

Picture

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/1000 sec., f/7.1, ISO 5000.

Above and  below we get a good look at the chick's really long feet and toes. For more on the anatomy of the bird foot (seriously, this is really interesting!) see this link to the Wikipedia entry Bird Feet and Legs, which includes photos of the African Jacana. 

Picture

The male jacana does all the parenting of the chicks, including tucking them under this wings and actually carrying them away from danger. I did not observe the "tuck and carry" move on this day, but an internet search reveals multiple images and videos of this behavior. Here is a link to a PBS Nature documentary on jacanas which was videoed in Africa, although the behavior is also common in the American species. Jacana Dad Rescues his Chicks from a Crocodile. 

This behavior is similar to that of the Sungrebe, but in the case of the jacana, the chicks are precocious, able to walk and forage almost right away, so the jacana dad has less reason to have a special underwing pocket.

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/2000 sec., f/7.1, ISO 8000.

What I did observe was the male Northern Jacana raising his wings repeatedly, as though to fly, only to pivot and bring them back down. Note that jacanas have very menacing looking bright yellow carpal spurs on each wing which are used in defense against predators, including other birds. 

Picture

Picture

Picture

Picture

For any nearby predators it certainly looks like dad is on patrol and not someone to mess with lightly! The young can see that dad's wings are there for protection if needed.

Picture

Southern Lapwing


Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/1000 sec., f/7.1, ISO 5000.

Southern Lapwings are in the plover family, living year round (non-migratory) from Central America all the way to the southern tip of South America. They live on grasslands and pastures, feeding on insects, small fish and aquatic invertebrates. 

Here we see a Southern Lapwing on grasslands adjacent to the river. They are striking birds, with a gray back and neck and a black chest patch that extends up the neck to the forehead. They have a long narrow crest, and like jacanas, a spur on each wing for defense. They breed during the rainy season, April to October, and within a day the chicks are out of the nest and feeding on their own. On this day we did not see any chicks. 
Picture

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/400 sec., f/7.1, ISO 1600.

During the non-breeding season, Southern Lapwings can be found in large foraging flocks, displaying mobbing behavior against predators such as the Southern Caracara. The wing spurs, evident below, provide an extra level of defense. 

Picture

In the image below we can see that the large black chest patch runs up the neck all the way to the forehead.

Picture

Below we can see the Northern Lapwing in flight with the wing spurs evident.

Black-collared Hawk


Picture

Late afternoon on the river, we spotted this Black-collared Hawk, first perched, then in flight, probably looking for dinner. Black-collared Hawks eat fish with an occasional lizard or rodent, but not other birds. They live near or on fresh or brackish water from southern Mexico into South America. See the eBird range map to the right. Black-collared Hawks sport a black bib, rufous feathers, and a very short tail.

Finally, for this season, the Kingfishers Three . . . .


Well, Christmas is upon us, and if we have been close to any recorded music, we have been regaled at least once with the three kings! Well, here are three kingfishers.
While there are over 100 kingfisher species worldwide, only 6 species call the Americas home. These six are: Belted, Ringed, Green, Amazon, Green-and-rufous, and American Pygmy.  On this day on a river in Costa Rica we spotted three of the six, gazing across the water looking for their next meal.

​Amazon Kingfisher


Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/1000 sec., f/7.1, ISO 1250, -0.67 EV.

Amazon Kingfishers are dark birds with a white collar and belly. The males sport a rufous breast, the females have a narrower green breast band. They live along lakeshores and slow moving rivers from Mexico to Argentina. See the range map to the right. 

​Amazon Kingfishers eat fish and crustaceans, hunting from a perch over the water. They grab their prey, smack it on the perch, and swallow it head first. As we can see in the images above and below, the bill is large and spear-like. 
Picture

Picture

​American Pygmy Kingfisher


Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/500 sec., f/7.1, ISO 1600.

The American Pygmy Kingfisher lives in tropical lowlands along quiet streams and swampy areas of lakes. Their hunting style is to perch low and stay concealed, diving for fish, tadpoles and small frogs. 

These kingfishers are very small as their name suggests. Here we see a male with a dark head and wings and rufous collar, throat and flanks. The female has a dark green breastband with white tips to the feathers (Ref: Birds of the World). 
Picture

Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/320 sec., f/7.1, ISO 640, +0.67 EV.

Green Kingfisher


Picture
Canon R5m2 with RF 100-500mm at 500mm, 1/320 sec., f/7.1, ISO 4000.

The Green kingfisher is slightly larger than the American Pygmy Kingfisher, but smaller than the Belted Kingfisher and the Ringed Kingfisher.  The female (seen here) has a white collar, buffy thoat and breast with speckled green bands across the breast and uppermost belly. The male has a rufous breast. 

Like other kingfishers they hunt from a perch where they can see prey in the water. They eat primarily small fish.

That is it for Cano Negro!  More coming soon!  Stay tuned!

Just in from Costa Rica: The Resplendent Quetzal!

11/20/2025

Canon R5 Mk II, RF 100-500mm at 500mm, 1/80 sec., f/8.0, ISO 2000, +0 EV. 

My wife and I just returned from two weeks in Costa Rica, where we toured three regions with Emily Carter and Holbrook Travel: first the wetlands of Cano Negro in the north, then the rainforest of Selva Verde further south, and finally the Talamanca Mountains in the province of San Gerado de Dota.  In San Gerado de Dota we stayed at the Savegre Hotel, Natural Reserve and Spa,  and on two successive mornings trekked a bit up the road to the edge of the cloud forest to look for the magnificent Resplendent Quetzal! 
Picture
This is my first post on Costa Rica, one of many posts planned!  Stay tuned!
The Resplendent Quetzal is a member of the Trogan Family, the only family in the order Trogonidae. There are two recognized subspecies of the Resplendent Quetzal, Pharomachrus mocinno mocinno, and P.m. costaricensis, the former Guatemalan, the latter Costa Rican, seen here. The Guatemalan subspecies lives in southern Mexico and Guatemala,  the Costa Rican in the mountains of Costa Rica and northern Panama. 
Picture
The Resplenent Quetzal is a magnificent bird, with arresting irridescent coloration, and a long uppertail covert feather sported by the male in breeding season. The species lives year round on their territories, although the Costa Rican quetzal will migrate locally within the tropical cloud forest depending on the season. 
We saw and photographed the quetzal at the end of the two week tour with Holbrook Travel, organized by our Tucson photography/birding buddy Jack, and led by the fantastic photographer and workshop leader Emily Carter, (Nature as Art), along with our  outstanding local guide and photographer, Andres Quiros, and of course Holbrook Travel. 

Picture

Andres Quiros is on the left bundled up against the pre-dawn chill, and Emily Carter is on the right, leading our group in search of the Magnificent Quetzal. Thanks to them and our fellow travelers, Jack, Linda, Tom, Barbara, Mike, Nancy, D.J., and Laurie, who all made the trip a big success and a lot of fun. And of course, Poppi, our expert bus driver, who negotiated narrow mountain roads with skill!
On November 6th we arose at 4 am (ugh!) for coffee and a short bus ride down the road where we hiked up the side of the mountain valley to a level field adjacent to the forest and wild avocado trees. These trees produce a small fruit that is a quetzal favorite, attracting them first thing in the morning.   

The map below shows our location in the mountains at about 7600 feet above sea level on the Pacific side of the continental divide.

Picture

We arrived at our site well before the 6 am sunrise and joined about a dozen other photographers, tripods set up, carefully examining the edge of the dense cloud forest and all the possible Quetzal perches. Finally, about 6:15 am the quetzal alert went out - a male was spotted in an avocado tree. 

Below, a "where's Waldo" photograph of a male Resplendent Quetzal perched behind the leaves. I resorted to manual focus to get the eye as sharp as possible (the autofocus options on my Canon R5 Mark II seemed to find everything but my subject!). 

Picture
Canon R5 Mk II, RF 100-500mm at 500mm, 1/200 sec., f/7.1, ISO 5000, +0 EV. 

5 minutes later he hopped out and gave us a nice back shot, below. The males are probably growing out their uppertail covert feathers* now for a breeding season that will begin in a few months. 

The back of the quetzal's head looks similar to the face and throat, a trait many birds share, and likely an adaption that confuses predators. If you think a bird is facing  you, you may be less likely to go on the attack.

* An earlier version of this post incorrectly identified the long feather the male grows in breeding season as a "tail feather" when in fact it is part of the uppertail coverts, the feathers that cover the base of the tail feathers. This makes sense, in that the tail feathers are essential for flight and vary by species, depending on the the nature of their flight, and patterns of acquiring food. The tail coverts contribute to better aerodynamics, and a long decorative feather as part of breeding plumage would logically grow from this group. My thanks to my friend, ornithologist /birder/professional photographer Steve Vaughan for picking this up. Thanks Steve!

Deep sigh . . not a great quetzal photo day. 
So, we decided to come back the next day for another try.

Up again at 4 am, coffee at 5 am, short drive down the road to the forest and our viewing spot, arriving at ~5:30 am. We were two days past the full moon, with our favorite planetary partner about to disappear over the western ridge of the mountain valley. It provided welcome light for our trek up the hill. 

Picture

I was at the back of our group as we we walked uphill, sharing the path with another photographer who whispered in my ear, "Look, a female on the branch above us!"

Sure enough, a female quetzal perched above us, image below.  The females have coloration similar to the males, but a bit more muted, and without the long tail the male grows in breeding season. 

These birds have a definite "cute factor", perhaps due to the short bill and large eyes on an open face. 

This photo was captured at 5:32 am, 30 minutes before sunrise. Definitely low light photography.

Picture
Canon R5 Mk II, RF 100-500mm at 500mm, 1/30 sec., f/7.1, ISO 4000, +0 EV. 

5 minutes later I was set up with our group for the morning show, when SUCCESS, a male Resplendent Quetzal was spotted on a perch, likely having just eaten an avocado. The avocados are small (more on this later) with thin flesh over a large pit. The quetzal does not pass the pit, but regurgitates it after digesting the fruit itself. So some digestion time is required. Why fly around with a pit in your stomach (literally!) when you can find a nice perch and wait!

Picture

Below, likely the same male on a different perch 40 minutes later and 20 minutes after sunrise in better light. The coloration varies with light and position of the bird, but is almost alway spectatular! Note the long tail dcovert.

Picture
Canon R5 Mk II, RF 100-500mm at 500mm, 1/80 sec., f/8.0, ISO 2000, +0 EV. 

Below, the same male 4 minutes later. It is not clear how many avocados a quetzal consumes at one sitting, but we can thank the pits for some great photo ops! 

Picture
Canon R5 Mk II, RF 100-500mm at 500mm, 1/160 sec., f/7.1, ISO 4000, +0 EV. 

This male probably barfed up a pit when I was fiddling with my camera settings, and then flew.
More on avocados. What we call avocados are the fruit, really a large berry, of the avocado tree, an evergreen in the laurel family. The avocado tree is common in the Americas, from Mexico through Central and South America. In addition to the cultivated  avocado we enjoy in salads and guacamole, there are many wild varieties that are small, with a relatively large pit in relation to the flesh or fruit. Below, beside the tip of the quetzal's tail, a small avocado on the tree of the same name.

Picture
Canon R5 Mk II, RF 100-500mm at 400mm, 1/125 sec., f/7.1, ISO 5000, +0 EV. 

Resplendent Quetzals eat primarily fruit, especially the small avocados seen above. Like other frugivores in Central America they are important agents of seed distribution throughout the forest, facilitating new tree growth.

Below, at 6:53 am, a young male quetzal arrives in a tree close to us. He is likely digesting an avocado.

The Resplendent Quetzal is a sacred symbol in many Mesoamerican cultures, representing freedom, divinity, and rebirth. The species was deeply revered by the Maya and Aztec peoples, a significance that endures today in Guatemala where it is the national bird appearing on the flag and the currency. 

It is difficult to estimate changes in population of this elusive bird, but they are considered "near threatened" with populations declining due to loss of habitat, the cloud forests. 

For more on the Resplendent Quetzal, see eBird, or  this essay from Living Bird magazine, Costa Ricans Join Hands to Cultivate A Quetzal Community, by Alan Poole.

That's all for now! 
More on Costa Rica soon!

Fall at El Rio Preserve, Part II:  Grebes and Warblers, with a little Chat on the side . . . . .

Common Yellowthroat at El Rio Preserve, September 21, 2025

For my last post on September 27th I visited El Rio Preserve in Marana, Arizona, and focused on one food, the dragonfly, which was in plentiful supply and provided breakfast for raptors, shorebirds and songbirds alike. In this post I return to El Rio and take a focused look at the Grebe family (Podicipedidae), including a rare one for SE Arizona, the Least Grebe. 

Least Grebe   (Caution: RARE BIRD ALERT!)


Picture
Canon R5 Mk II RF 100-500mm & 1.4x Ext. at 700mm, 1/1600 sec., f/10, ISO 1600, +0.33EV.

The Least Grebe, like its cousin the Pied-billed Grebe, is a small duck-like water bird that lives on fresh and brackish water ranging from the Rio Grande Valley in Southern Texas all the way into South America. See the range map to the right.

Least Grebes live year round within their range, so it is unusual to see one in Arizona, although as one might expect, eBird has sightings in Arizona, where it is considered a "causal resident", present intermittently throughout the year. This solitary Least Grebe has been sighted at El Rio Preserve repeatedly in September and October.  See the eBird range map below for the Least Grebe sightings in our area.
Picture

In the image below our subject is fluffing up his white behind and turning it into the sun to warm up the underlying dark skin. This behavior is shared by other grebes, as well as the Greater Roadrunner (See Sweetwater Wetlands, Winter 2025).

Picture
Canon R5 Mk II RF 100-500mm & 1.4x Ext. at 700mm, 1/1000 sec., f/10, ISO 1000, +0.33EV.

Below, our solitary Least Grebe at El Rio Preserve is floating in a raft of multiple Pied-billed Grebes, all preening in the morning sun. Pictured side by side, these two grebes are in roughly the same focal plane, making it is easier to make comparisons.

Picture
Canon R5 Mk II RF 100-500mm & 1.4x Ext. at 700mm, 1/2000 sec., f/10, ISO 2000, +0.33EV.

The Least Grebe is dusky gray with a bright yellow eye and a thin and pointed bill with a light tip. In contrast, the Pied-billed is larger and browner with a thicker, stubbier bill.  Below, the two grebes are closer to each other for a better comparison, the Least Grebe on the right, the Pied-billed on the left.

Picture
Canon R5 Mk II RF 100-500mm & 1.4x Ext. at 700mm, 1/1000 sec., f/10, ISO 1000, +0.33EV.

Below, the two birds are even closer with the Least Grebe in the foreground, his eye partially closed.  

The two species seemed to get along, although I noticed that as they preened, they seemed to fluff up more when closer to the opposite species.

Pied-billed Grebe


Picture
As noted above, Pied-billed Grebes are larger than the Least, and very common in SE Arizona. Above, two Pied-billed's at El Rio, and to the right the Pied-billed range map. The Pied-billed Grebe has an extensive range, living year round in most locations, but with some populations migrating to the northern U.S. and into Canada for summer breeding. 
Picture

Below, a close up of a Pied-billed Grebe at Sweetwater Wetlands in January of 2022. Breeding adults have a vertical black stripe on the bill. This grebe is a non-breeding adult.

Below a photo of a Pied-billed Grebe swimming on one of the ponds at Sweetwater Wetlands in February of 2020. All grebes have their feet positioned far back on their bodies, a bit like an outboard motor on a rowboat. Also, they have lobed toes, seen here just to the right of the center of the photograph. The combination of leg placement and lobed toes make them great swimmers, allowing them to dive and maneuver under water for prey. However, they are not good walkers and are rarely seen on dry land.

Picture
Canon 7D Mk II EF 100-400mm at 400mm, 1/1000 sec., f/5.6, ISO 400, +0 EV.

Pied-billed Grebes eat crustaceans, small fish, and whatever is available, including frogs! 

To the right we see a Pied-billed Grebe downing a frog at Sweetwater Wetlands in January of 2016. Yes, he did manage to swallow the whole frog, head first!

For more, see the post "Grebe eats frog!", or "I can't believe he ate the whole thing!"

Clark's Grebe


Picture
Canon 7D Mk II EF 100-400mm w/ 1.4 x ext. at 560mm, 1/640 sec., f/8, ISO 320, +0.67 EV.

This Clark's Grebe was spotted at Patagonia Lake State Park in March of 2019. The bird was on the far side of the lake with a lot of moist air between us, creating a slightly fuzzy image in spite of good focus and low ISO. 

Clark's Grebes live year round in Mexico, with populations migrating north to the western U.S. and into Canada. They frequent lakes and coastlines. See the range map to the right. This bird may have been migrating north for breeding at the time of the photograph. 
Picture

Picture

Clark's Grebes are black and white with long curved necks and long pointed orange bills. They are known for a dramatic courtship display, or "rushing ceremony" on their breeding grounds.

Eared Grebe


Picture
Canon 7D Mk II EF 100-400mm at 400mm, 1/1000 sec., f/6.3, ISO 160, +0.33 EV.

The Eared Grebe has a thin bill and a bright red eye, seen here in non-breeding plumage. The  grebe pictured here was spotted at White Water Draw in December 2019. 
​
​Eared Grebes breed in colonies in shallow wetlands in the western U.S. and Canada.  In the fall, after breeding, they head by the hundreds and thousands to salty inland waters, especially Mono Lake in California and the Great Salt Lake in Utah to stuff themselves with brine shrimp before heading farther south for the winter. This coincides with their fall molt providing the high calorie intake required for new feather growth.  
​
Range map is to the right.
Picture
During this feeding phase they more than double their body weight with the digestive organs growing and the pectoral muscles shrinking to less than required for flight.  Before departure for wintering grounds the process reverses, with the digestive organs shrinking to one-fourth of peak size, and the heart and pectorals growing quickly to allow for flight. ​

In the image above, like other grebes, our subject has his "bum to the sun" to warm up on a cold December day.

Let's Wrap-up with Three Warblers and a Chat . . . .

In addition to the rare (or at least "casual") Least Grebe at El Rio, I spotted three warblers, plus a "used-to-be warbler," a Yellow-breasted Chat. Let's take a look . . . .

Common Yellowthroat

Picture
Canon R5 Mk II RF100-500mm with 1/4x Ext. at 700mm, 1/1000 sec.,f/10, ISO 1250, +0.0 EV

The male Common Yellowthroat with his bright yellow duds and black mask looks like a mysterious highwayman, but rest assured, he is only after insects and spiders from the local leaves and branches!

​The Common Yellowthroat favors the edges of marshes and wetlands, breeding throughout the northern U.S. and Canada, wintering in Mexico with year round populations in Florida and the SE U.S. 

The adult male above was spotted at El Rio on September 21st at 7:30 am, with just enough morning sun to catch a light on the eye and create a subtle shadow on the breast. 
Picture
Below, an immature male "highwayman in training,"  with a faint and patchy mask.

Yellow Warbler, Immature Male

Picture
Canon R5 Mk II RF100-500mm with 1/4x Ext. at 700mm, 1/2000 sec.,f/10, ISO 8000, +0.67 EV

In the spirit of full disclosure, I was not sure which species this bird was, and so as is often the case, I consulted the guru app Merlin, which gave me four choices of warbler, in descending order: Yellow, Nashville, Tennessee, or Orange-crowned. The apparent eye-ring was nudging me toward Nashville, but not being sure, I consulted the real expert, Jeff Babson! 
Jeff as always came through and told me that this looks like an immature Yellow Warbler. A Nashville would show more gray on the head, and the Tennesee and Orange-crowned would show an eye line. Young Yellow Warblers often have a more distinct eye ring than adults because the yellow is not as brilliant.  

Yellow Warblers are insectivores who winter in Central and South America and breed all the way from Mexico to Alaska, coast to coast! See the range map to the right. The birds pictured here are likely on their way south for the winter following the food!
Picture

Picture

The photograph below was shot 30 minutes later.  This may be the same bird, with the eye ring looking smaller because of the angle, or perhaps a female.

Picture

Yellow-rumped Warbler

Picture
Canon R5 Mk II RF100-500mm with 1/4x Ext. at 700mm, 1/2000 sec.,f/10, ISO 800, +0.0 EV

Our third warbler for the day is the Yellow-rumped Warbler, Audubon's. They have a yellow rump ("butter butt"), a yellow patch on the throat, and yellow patches ("pits") under the wings. 

Yellow-rumped Warblers have a wide range, living from the Pacific to the Atlantic and Caribbean, breeding as far north as Alaska, and wintering into Central America. They eat a wide variety of insects during the summer, as well as fruits during the winter. Unlike most warbers, their digestive tracts are capable of digesting fruit, which allows a wider range especially further north in the winter.
Picture
For more on the Yellow-rumped Warbler see this page:  Yellow-rumped Warbler.

And Finally, a Yellow-breasted Chat!

Picture
Canon R5 Mk II RF100-500mm with 1/4x Ext. at 700mm, 1/500 sec.,f/7.1, ISO 12800, +1.0 EV

For years the Yellow-breasted Chat was in the warbler family, Parulidae, but in 2017 it was given its own family, Icteriidae based in part on its large size and complex and varied vocalizations. Although wide-spread, it is generally only seen in the spring when singing, and is otherwise skulking in the shadows of dense thickets and therefore tough to spot. I spotted this bird briefly, and only once, at sunrise, 6:30 am, on September 21st, and in the shade! Once the sun was up, he was gone! 
Picture
Yellow-breasted Chat's eat insects, as well as fruits and berries. 

That's a wrap! Four grebes, three warblers, and a chat!

El Rio Preserve is Now Serving Dragonflies for Breakfast!

Immature male Vermilion Flycatcher with a Dragonfly, El Rio Preserve, Sept. 20, 2025.

September 20th and 21st my wife and I ventured to El Rio Preserve in Marana* to see which of our avian friends were there to welcome the first day of fall**.  We started as early as possible, making it to pond-side by 6 am on the 21st (not so early on the 20th).  There was an abundance of insects, especially Dragonflies. So many in fact, that they made it to the top of the morning menu. Here are three species shifting their diets ever so slightly in the dragonfly direction that morning.

* Here is a link to a prior post on El Rio: El Rio Preserve: Fall 2024
** September 22nd at about 11am in Tucson.

An American Kestrel Grabs Some Take-out . . .


Picture
Canon R5 Mk ii, RF 100-500mm with 1.4x Ext., at 700mm, 1/2000 sec., F/10, ISO 1600, +0.33 EV.

American Kestrels* are raptors, North America's smallest falcons, about the size of Mourning Doves. They commonly perch on high branches or telephone wires, diving to the ground after rodents, or grabbing insects in the air. They favor open areas with short ground vegetation and sparse trees, including meadows, grasslands, farm fields and parks. They are regulars at El Rio Preserve.

The female kestrel above was perched on a high snag over the lake, just north of the main viewing deck near the parking lot. After I captured this image she took off to the east, to my right as I was standing, and disappeared into the wetlands. As she flew back to her perch I was able to get her in my viewfinder and shoot ~16 frames before she landed.

Below, she is in mid-air on her return flight.


* For more posts on American Kestrels see: New Year's Day 2018 at Fort Lowell Park.

Picture
Canon R5 Mk ii, RF 100-500mm with 1.4x Ext., at 700mm, 1/4000 sec., F/10, ISO 2500, +0.33 EV.

Female Kestrels are rusty overall with black barring on the wings.  Males have slate blue wings with a more pronounced blue crown. In this image we can see that she is carrying something in her talons. 

In the image below the wings are up and we can see she has probably two dragonflies in her talons. Her rusty tail is in good light.

Picture

Below, we see more detail of her prey, including what looks like a blue body. She appears to be carrying her prey with one talon, leaving the other free for a safe landing. 

Picture

Below, the kestrel has landed!

American Kestrels are raptors with sharp, hooked bills. She will likely eat the whole dragonfly starting with the head. 

To see a kestrel lunching on a songbird at Ft. Lowell Park, go to the post Lunch time in Ft. Lowell Park. Caution: This post show a kestrel eating what is probably a Lark Sparrow piece by piece including the feet!

A Black-necked Stilt Swallows Them Whole . . . .


Picture
Canon R5 Mk ii, RF 100-500mm with 1.4x Ext., at 700mm, 1/2000 sec., F/10, ISO 3200, +0.67 EV.

Black-necked Stilts are stately shorebirds with year round populations in North and South America, as well as breeding grounds in the western U.S. They are short to long distance migrants, and Tucson is in their migration range. For more on Black-necked Stilts, and to see them in flight at Canoa Ranch, see my prior post: Historic Canoa Ranch April 2022.

As wading shorebirds, Black-necked Stilts eat aquatic invertebrates, small crustaceans, amphibians, snails, and tiny fish. They also prey on larval mosquitoes, soldier flies, brine flies, caddisflies, dragonflies, mayflies, crickets, grasshoppers, beetles (including weevils), water-boatmen, crayfish, brine shrimp, tadpoles, and very small frogs and fish. (Ref: All About Birds). 

Here we see a Black-necked Stilt working on a dragonfly, paring it down to size for the "big gulp."   

Images above and below, lifting the prey from the water in the process of meal prep! 

Picture

Picture

I have probably caught this stilt somewhere in the process of disassembling his breakfast. Above and below, the dragon fly still has sizable wings.

Picture

Below, this dragonfly had four wings when still flying, now apparently down to two. 

Picture

Picture

Above and below the stilt whips the dragonfly back and forth . . .

Picture

Picture

Male and female Black-necked Stilts look alike, but I will assume this is a female. After a few shakes of the dragon fly she dunks it back in water and continues her food preparation. 

In this case playing with your food is not only okay, but an important part of the meal.

Picture

Picture

Picture

Picture

We see a bit more of the dragonfly itself in these frames. The wings don't come off easily!

Picture

Picture

Picture

Above, she drops the dragon fly.  She picked it up again (not shown), and repeats the whole process. The second round took about a minute and occupied ~35 frames, none of which are shown here (mercifully!) 

Below, after the second round she is finished pounding her prey and considers actually eating!

Picture

Below, our subject has taken the dragon fly into her mouth and turns 180 degrees. There is subtle bulge in the neck

Picture

Below, she takes a big gulp. We can see just a bit of dragon fly wing sticking just above the bill . . . 

Picture

seen more clearly on the cropped image below! 

Picture

Bird species that live on the water eat a wide variety of food, including some large prey.  As an example, below is a link to a prior post:
From 2016, a Pied-billed Grebe downs a bullfrog at ​Sweetwater Wetlands.

Canon R5 Mk ii, RF 100-500mm with 1.4x Ext., at 700mm, 1/4000 sec., F/10, ISO 1250, +0 EV.

Vermilion Flycatchers are year round residents of SE Arizona, and one of the most colorful flycatchers to watch. They are "sit and wait" predators, sitting on a perch, flying out for prey, then returning. Most of their diet consists of small flying insects. However, research (Ref: Birds of the World) has shown that they will capture grasshoppers and butterflies, which they bring back to their perch and beat before eating. There is no mention specifically of dragonflies. My guess is that this immature vermilion will take his catch to a larger perch nearby and eat  at least portions of it in pieces. Or, maybe he will just drop it!

That's all for now! 
More coming soon.

Rufous Hummingbirds: Fall Visitors on Their Way South

9/18/2025

0 Comments

 
Picture

This post focuses on a single species, the Rufous Hummingbird, with a special section in the second half just for all you photo geeks out there who want to learn more about using fill flash for your hummer photography at shutter speeds up to 1/8000th second, also know as "High Speed Sync (HSS)."  (If you love birds, but not cameras, don't quit in the middle, there are lots of fun photos in second half!)

Rufous Hummingbirds are feisty long distance migrants who make a regular stop on Mt. Lemmon in the summer and fall. Every spring they fly from their wintering grounds in southern Mexico or the gulf coast all the way north to the Pacific Northwest (2700 miles one way),  or western Canada and Alaska (up to 4,000 miles) for breeding, then back again! We see them on their way south.

The image above was captured in Summerhaven on August 23, 2025. We see three females or immature males creating a bit of a ruckus at a nectar feeder. Every summer the males are the first to migrate south, arriving in Summerhaven in early July, followed by females and immature males. By early September the gang has moved south into Mexico. 

Below, a picture of a male Rufous captured on March 16, 2018 at Battiste Bed, Breakfast and Birds in Hereford, Arizona.  Tony and Julie Battiste run a fantastic B&B with a large backyard feeding/viewing area, including a photo blind. This Rufous male was on his way north to breed, and stopped to get breakfast at their feeders. 

Male Rufous are orange on the back and belly, with with a mix of white on the throat and a vivid iridescent-red gorget that varies in color and intensity depending on the angle of the light.

In the spring Rufous Hummingbirds leave their wintering grounds to migrate north up the Pacific Coast, following the food (flowers and insects) up to the Pacific Northwest  and Canada/Alaska.

Males mate and take off early for the south, this time traveling down through the Rocky Mountains following meadow flowers. SE Arizona is one of their stops on the way to Mexico.

​The females and new offspring follow the males on the same route, arriving in Summerhaven usually in August.

The photographs above and below show the variation in color of the gorget depending on the angle to the sun and in this case, my speedlite. In the absence of good light the gorget looks dark brown.

Rufous Hummingbirds are very aggressive at feeders, both with other species and with their own. Below we see what appears to be three females/immature males facing off near a feeder, with two other birds perched on the tray. This is a wider angle view of the image that leads this post.

​One Rufous, often a male, may work to dominate several adjacent feeders at the same time, claiming them as "his" and shooing off other hummers. The only species I have seen that ignores the Rufous is the Rivoli's Hummingbird, one of the largest hummers in North America, and clearly bigger than a Rufous. ​
Below, from July 29, 2020, a Rivoli's Hummingbird sitting on the left at the nectar feeder, with an immature male Rufous gingerly landing on the opposite side. This is one of ~10 images that showed the young Rufous circling and approaching the Rivoli's, while the larger and clearly more dominant Rivoli just sat and drank, ignoring the Rufous.

You need a lot of calories to fly ~5,000 to 6,000 miles a year. Staking out and defending food sources along the way is essential.

For the photo-geeks: As promised in the intro, here is more on the use of fill-flash for hummingbird photography using high-speed sync, or HSS. If you are not a photo-nut, don't leave now, the images that follow show more fun hummer aerobatics! 

Back in the day of  mechanical shutters, one could not use flash, even with high tech strobes, with shutter speeds over ~1/250 second. If you could, the shutter would not synchronize with the flash burst, resulting in only portions of the frame being illuminated. This restriction made the use of fill flash, putting in just enough light to "fill in"  darker portions of the photo, difficult for fast moving objects. I have used fill flash for hummingbirds at shutter speeds of 1/200 second, and if the bird was hovering in a stable position, I could get the eye and bill sharp, with blurring of the wings, which can look really cool. However, if the bird was darting here and there, which is often the case, everything gets blurred. 

I recently discovered that high speed sync was introduced in 1995, but it has taken me 30 years to discover it. (Only the newest, hottest stuff on this blog!)  Oh well . . .

In all fairness, it took the advent of  electronic shutters ~ 7 years ago, to make HSS more practical. And for action photography, it took stacked sensors and rapid readout to minimize rolling shutter on electronic shutters, necessary for high speed subjects like race cars and hummingbirds.  So, the manufacturers are now able to pair their speedlites (strobes) with their cameras to create a burst of rapid flashes that allows the photographer to use higher shutter speeds with flash and get even and predictable light on the subject, with minimal rolling shutter.

The image above, and the ones below, as well as a few in the preceding section, were all taken with a Canon R5 Mark II with a 580 EX II Speedlite set to HSS. 

Picture
Canon R5 Mk II, RF 100-500mm at 400mm, 1/2000 sec, f/8, ISO 3200, +0 EV,  flash fired in HSS mode.

In regard to set up, I can only speak to my Canon gear. Note that HSS is available in several other brands. 

​For a Canon R5 Mk II, first put a compatible speedlite on the camera. I have an aging 580 EX II, and it works.  Turn on the speedlite.  Turn on the camera, then go to the Red Menu (little camera icon) , second tab (2/9), and click on External Speedlite Control.  Scroll down to Flash Function settings and click on it. You will see the screen  below, left.
Picture
Picture
Select the box at the lower left (red on the screen) which takes you to the Shutter synchronization screen, above on the right. Click on the far right box, High-speed synchronization. A little High Sync icon lights up on the speedlite LCD screen (not shown). Note that the camera/speedlite combination stays in HSS mode even if both the speedlite and camera are turned off and then on again, but it loses the setting if the batteries of the speedlite are changed. If the batteries run low and you need to change them out for fresh ones, you will need to repeat the set up above.

Picture
Canon R5 Mk II, RF 100-500mm at 400mm, 1/2000 sec, f/8, ISO 3200, +0 EV,  flash fired in HSS mode.

Final steps: add a Better Beamer to the speedlite, set the speedlite in manual mode at ~1/15 power. I usually shoot at 1/2000 to 1/4000 second, hand held.  Although I usually shoot birds in manual mode with the ISO on Automatic, for HSS I got more predictable results setting the ISO at a fixed value, in most cases between 2000 and 4000. Check your exposure and adjust settings as needed.

On many of my usual hummer shots the birds are side-lit or back-lit, creating shadows that are hard to deal with.  The speedlite with the Better Beamer puts just enough light on the bird to get the colors and feather detail to "pop" and add a highlight off of the eye. 

Picture
Canon R5 Mk II, RF 100-500mm at 500mm, 1/2000 sec, f/8, ISO 2000, +0 EV,  flash fired in HSS mode. This bird was lit mostly from behind. The flash filled in the chest and tail, and lit up the spot on the gorget.

Below, a female/immature male coming in for a landing at the feeder. I love the landing pose; feet out, wings back, tailed flared and bill open just a smidge. The flash fills in the detail on the chest and throat, and adds a highlight to the eye. In fact, the bird appears to have two highlights, perhaps one from the flash and the other from incident light.  Full disclosure: I did use the Remove tool in Lightroom to take out part of the nectar bottle in the upper right corner.

Above and below, additional shots of the Rufous in flight competing for time at the feeder which was off frame to the right of these images.

One remaining challange: Depth of field. In the image above the Canon R5 Mk II does a good job of locking onto the eye of the lower bird in the frame, but the upper bird is just out of the range of focus. I was shooting at f/8.0, and at f/11 or higher, I might have had both birds in focus. At high f-stops the depth of field increases, but there is less light hitting the sensor, so the ISO goes up. For the most part in 2025 high ISO's can be corrected for with post-production noise reduction software such as Topaz De Noise. 

For a great video on autofocus in Canon cameras, especially the R5 Mk II, see Rudy Winston and canon autofocus explained.

Picture
A female Anna's Hummingbird sitting at a breakfast buffet at 7:20 am, August 7th at Sweetwater Wetlands . . . 

Hummingbirds are small highly active birds with high energy demands who consume large amounts of nectar during the day. However, they also need protein which is supplied by insects.  We are accustomed to seeing hummers at feeders and flowers, but they also are on the prowl for bugs . . .   

Above, a female Anna's sitting on a branch, which in fact, is her early morning breakfast buffet!  Below a close up of the entrees . . . .

Picture

It is unclear what type of insects these are, or whether they are in a breeding habitat, or have become ensnared in a type of cobweb. 

Below, our subject looks up, then to the right, likely looking for flying insects. Hummingbirds will "hawk,"  alighting from a branch to catch an insect in flight.

In the sequence below, she looks to the left, then down, where she spots the small insects ensnared on the branch.

Picture

Picture

Mouth open, she reaches down for breakfast . . .

Picture

Above, she grabs her prey, and below, pulls it up, along with some sticky webbing.
​For the Photo Geeks:  It was 7 am at Sweetwater Wetlands and I was walking on the south side of  the eastern ponds when I spotted this Anna's perched on a branch. Hand holding my Canon R5 MkII with a 100-500mm zoom and 1.4x extender, I set a high frame rate and waited for the bird to take off, hoping for inflight photos. My shutter finger was more active than the bird, and as expected, I got dozens of  perched bird photos! When I got the images home on my computer, I discovered this sequence, and was just able to make out the bugs on the branch! ​

Picture

Bugs in webbing, like a sticky-bun, can be a bit of a mess first thing in the morning . . 

Picture

Bug and webbing free of the branch, she scarfs them down! Always careful, she closes her eyes as she catches her prey.

Below, she is back to her foraging position, then looks down again.

Picture

Yup, there is more . . .

Picture

Yum yum, more goodies . . .

Picture

She snags her bugs and webbing, and in the sequence below seems to use her tongue to scarf down the insects.

Picture

Picture

Picture

Picture

More for the Photo Geeks: The sun was to my right and a bit in front of me, with an early morning milky sky in the background. The webbing and the sky are a similar grey color. Post-production I used a brush in Adobe Lightroom to increase the contrast between the webbing and the sky. I am assuming that the lighting resulted in the bird's tongue appearing white.

Above, she looks left again, then right, the decides to take off for the next stop on her early morning "cafe crawl . ."

Male Anna's Hummingbird at a feeder, Patagonia, Arizona, February 2, 2018.

Anna's Hummingbirds live year round on the Pacific Coast from Baja to Canada, including southern Arizona. See the range map to the right. To see a recent post on Anna's, including feeding at flowers in Tucson, see Anna's Hummingbirds in the Valley, or click on the photograph above.

Anna's Hummingbirds have been extensively researched. For an excellent list and description of all prior research, see Birds of the World (subscription required).  Of interest, observational research in the 1970's showed that male Anna's spent ~10% of their daylight hours feeding on nectar, and ~1% feeding on insects. 
Picture
So, if you see a hummingbird feeding, odds are 10:1 it will be at a flower or a feeder. It is also easier to spot a hummer hovering at a feeder than darting midair hawking flies! 
​
​A separate study estimated that an Anna's requires 38 mg of protein a day, which can be met by consuming 38 "average flies", assuming each fly is 60% protein and 80% of the protein is utilized. Kind of like catching an occasional 'burger amid a steady diet of snow-cones! 

That's all for now!

July 2025: Summerhaven on the way to Marshall Gulch, a Raptor and Three Songbirds!

Virginia's Warbler, Summerhaven, July 13, 2025.

American Goshawk


Picture
Canon R5 Mk II, RF 100-500mm with 1.4x Ext. at 700mm, 1/2000 sec., f/10, ISO 2000, EV +1.0.

My wife and I went birding with our friends Jim and Marty on Sunday morning July 13th, walking down Sabino Canyon Parkway toward Marshall Gulch. Just south of the water department we spotted a raptor on one of the trees recently burned in the Bighorn Fire. The bird was really far away, uphill, and well,  since common birds are common, we suspected it was a Cooper's Hawk, and kept on walking! As always, I took photos . . . 

I downloaded the photographs to my computer on Monday.  To confirm the species,, I took a photo of the computer screen for Merlin Bird ID (Cornell). Merlin was very persistent, telling me more than once that this was not a Cooper's Hawk, but an American Goshawk, one of three related accipiter* species in the U.S.

*Don't click on your dictionary app, I will explain "accipiter" below.

Picture

The American Goshawk, formerly know as the Northern Goshawk, is an accipiter like the Cooper's and Sharp-shinned, but a bit larger. The American Goshawk lives and breeds away from human populations and is very protective of their nests and aggressive towards people or animals that get too close!  Therefore, spotting one it is a relatively rare occurrence. One of the distinguishing field marks is the bold white eye-line above the eye, seen in the photo above.

Below, the Goshawk crouches and takes off. 

Picture

Picture

The Goshawk is larger than either the Cooper's or Sharp-shinned, and and like all the accipiters the females are larger than the males. 

Picture

Below, a view of the extended right wing. The accipiter wing has a low aspect ratio, being short in relation to its width. More on this in a minute.

Picture

SE Arizona is in the American Goshawk's territory, but we are unlikely to spot them often given their aversion for people. Mating pairs in the west will build nests high in the largest trees, usually firs or pines. Clutch size is 2-4 eggs. 

The American Goshawk is in the Order Accipitriformes along with ospreys, hawks, eagles, kites, and vultures. 
Picture
​Of the 4 Families in this order, the Goshawk is in the Family Accipitridae. Within this Family there are several Genera, with the goshawk being in the Genus Accipiter, along with the Cooper's and Sharp-shinned hawks. 

​Accipiters (the Genus) are slender with short, broad, rounded wings and a long tail. They often ambush their prey, mainly small birds and mammals, capturing them after a short chase. The typical flight pattern is a series of flaps followed by a short glide. They are commonly found in wooded or shrubby areas. (Wikipedia).


Buteo is another Genus in the Family Accipitridae,  and includes the hawks we commonly see in SE Arizona, including the Red-tailed, Zone-tailed, Swainson's, and Ferruginous. 

So, Goshawks, Cooper's and Sharp-shinneds are commonly referred to as "Accipiters," and Red-tailed and Zone-tailed as "Buteos," after their respective Genera.  In the field these two Genera look and fly differently, with Accipiters flapping and gliding, and Buteos commonly soaring.  
In flight accipters and buteos look different. As previously noted, Accipters have lower wing aspect ratios (length/width) compared to buteos. For illustration, below are two images, on the left the Goshawk we saw on Sunday July 13th, and on the right a Red-tailed Hawk captured on Mt Lemmon in October of 2023. 
Picture
Picture
The goshawk has shorter and wider wings. These wings are good for quick maneuvering in tight spaces, making catching birds in flight easier.
The Red-tailed Hawk has longer more narrow wings (higher aspect ratio) good for efficient souring on thermals, in search of prey on the ground.

Although we did not see other accipiters on Sunday, this is a great time to reach into the archive and catch up on the other two accipiters we do see in the U.S., Cooper's and Sharp-shinned Hawks.

Cooper's Hawk


Picture
Canon 6D, Sigma 150-600mm at 600mm, 1/640 sec., f/9, ISO 200, EV +0.

Cooper's Hawks live throughout North America and into  Central America. Unlike Goshawks, Cooper's are comfortable around people, and often nest in trees in close proximity to houses. They are skillful in the air, chasing birds or making tight turns around buildings to attack a back-yard feeders, often forcing prey into windows. 

The photograph above was captured at Whitewater Draw in McNeal, Arizona, in December of 2015, the image below at Sweetwater Wetlands in Tucson in January of 2021.  
Picture
Note that the eye color of the Cooper's varies from blue to blue-gray as a nestling to yellow as juveniles, then to yellow/orange or red as adults. (Ref: Avian Recon.)  The bird above is likely a juvenile, the one below an adult.

The image below was captured a week later, June 8, 2017. The nestling is now a fledgling, sitting on an adjacent branch, left leg down, right leg tucked up. Note that the eyes are grey/yellow.

Sharp-shinned Hawk


Picture
Canon R7, RF 100-500mm at 500mm, 1/4000 sec., f/7.1, ISO 3200, +0.67 EV.

Sharp-shinned Hawks are the smallest of the accipiters we see in the U.S. Their flying and hunting behavior is similar to the Goshawk and Cooper's, employing flap and glide technique with tight turns to catch birds in flight, usually the size of an American Robin or smaller. They breed in Canada, building a broad flat nest high in conifers, and winter to the south, although there are many regions with year round populations. See the range map to the right. In SE Arizona we will see them during the winter, but being close to year round populations we may see them during the summer breeding season as well.
Picture
​Sharp-shinned's are similar in appearance to Cooper's, but in flight the Sharp-shinned has a short wide neck with the head in-line with the wrist joints on the wings, evident in the image above.The tail is long and squared off, whereas the Cooper's has a more curved tail. Sharp-shinned's are commonly spotted at hawk watches in the fall. 

The image above was captured at Agua Caliente in December of 2023.

In addition to the American Goshawk, we spotted some songbirds, including this Virginia's Warbler. ​
Virginia's Warblers winter in southern Mexico and breed in the forests of Arizona, New Mexico, Nevada, Utah and Colorado. They are ground nesters, favoring steep slopes below clumps of vegetation. (Ref: All About Birds) . 

Virginia's Warblers eat insects, favoring caterpillars, spiders, ants, weevils, stinkbugs and flying insects. 

In the images here we see a Virginia's Warbler looking for breakfast in the understory adjacent to Sabino Canyon Parkway in Summerhaven.  

​
Picture
Virginia's Warblers are gray with yellow at the tail and on the breast, and a bold round eye-ring, which we can see in the images above and below.

Western Flycatcher, AKA Cordilleran . . 


Picture
Canon R5 Mk II, RF 100-500mm with 1.4x ext. at 700mm, 1/500 sec., f/10, ISO 3200, +0.67 EV.

In 1989, the Western Flycatcher was split into two separate species, the Pacific Slope and the Cordilleran. So, for the past 30 years we have been seeing the Cordilleran Flycatcher, considered the mountain cousin of the Pacific Slope, nesting in Summerhaven.

However, in 2023, the two species were reunited (if they had a party, I was not invited!) as the Western Flycatcher. So, all you Cordilleran fans are now looking at, and loving, Western Flycatchers. Yahoo ! 
Picture
Above and below, images of a Western Flycatcher near Sabino Canyon Parkway on July 13th. Note that this bird has a yellow band on the left leg, and a metal band with ID number of the right leg (metal band just barely visible, ID number is not).​

Picture

Western Flycatchers are small flycatchers in the genus Empidonax (Empids) that winter in Mexico and return to mountain riparian habitats to nest each year. They are greenish brown above, and pale below with a large head and a straight bill, wide at the base. They eat insects and nest on flat areas, including platform nests built especially for them. 

Picture

In 2019, Dr. Charles Van Riper III moved his summer research on the Cordilleran Flycatcher (COFL) from Colorado to Mt. Lemmon. He worked with Dr. Harold F. Greeney, the two of them shown at the right taking a break from banding and tracking COFL's in Summerhaven in 2019.

​Unfortunately we lost Charles this past winter after a short illness. Everyone here on the mountain who were part of his "COFL Network" miss him dearly. Summer on the mountain does not seem right without him. 
Picture
The bird shown above was likely banded by Charles or Harold in prior years. Charles' research has demonstrated that the birds he banded tended to return to Summerhaven to nest in subsequent years, sometimes in exactly the same spot. 

Below, a platform nest built especially for the Western Flycatcher with a female sitting on the nest on July 13th. It is not clear if she is incubating eggs or not. Mid-July is a bit late for breeding, and this could be a second try for this season.

Mt. Lemmon, July 2025: On the Edge of the Monsoon . . . .

7/6/2025

Red-breasted Nuthatch, Bear Wallow, Mt. Lemmon, June 27, 2025.

I sit down to write this on Saturday, June 28, 2025, hopefully at the end of a very dry spell! Weather maps show a high pressure area moving toward four corners, with a prediction of monsoon rains beginning this Tuesday, July 1st. However, the hope of rain is not the same as water, and things are really dry up here today! 

Birds are here, but not in much evidence. This past week my wife and I walked Marshall Gulch and Bear Wallow*, with the greatest activity around a puddle (literally!) in a stream bed on the way from Bear Wallow to Mt. Bigelow. We then capped off June at the Meadow Trail on Sunday the 29th, a pause from writing this blog! 

One of our finds (thanks to a fellow birder!) was a somewhat scruffy looking Red-breasted Nuthatch in Bear Wallow. Makes me want to go nuts over hatches . . . (groan!).

​So let's take a look at Nuthatches!

*My thanks, as always, to Jeff Babson, ace naturalist, who led one of his classic  birding expeditions to Bear Wallow on the 27th!  Thanks Jeff!

Mixed Nuthatches: Red, White, Brown, and  Oh, Yes, the Tiny Ones, Pygmy!

Granted, not all these nuthatches were in Bear Wallow on June 27th, but I could not resist the lure of "mixed-nut hatches . . "  Bear with me (in Bear Wallow . .  LOL!!). And only one cup of coffee so far this morning . . . 

Red-breasted Nuthatch


Picture
Canon R5 Mk II, RF 100-500mm w/ 1.4x Ext. at 700 mm, 1/500 sec., f/10, ISO 5000, EV + 1.67.

Red-breasted Nuthatches live in the north woods and western mountains, living year round or migrating short distances. They are one of what is known as irruptive species, those that move outside their usual range in great numbers in years when local food  is scarce. Red-breasted Nuthatches eat insects during summer breeding, but switch to conifer seeds in the fall and winter. In years with low cone production they will move outside their usual range looking for seeds. This accounts for the very wide area of non-breeding regions on the range map to the right. 
Picture
This irruptive behavior tends to occur on a two year cycle. For the bird observer this means that there will be years with no Red-breasted Nuthatches in the local neighborhood, and others where they will suddenly be seen in large numbers, especially in regions of the southeast. A bird of the Northwoods may suddenly appear on the Gulf Coast.​

Picture

Above and below, a Red-breasted Nuthatch in Bear Wallow on June 27th looking for insects. In typical nuthatch fashion, they will hang upside down as they forage. Red-breasted Nuthatches have a sharp bill, a short tail, a black crown with a white eyebrow and a black eyeline. They are blue-gray above and rusty below. This bird may be a female or juvenile, with paler underparts. 

Picture

The two images below are a Red-breasted Nuthatch caught on the Meadow Trail, Mt. Lemmon, in August of 2021. I have included the images here to show what is likely a male with brighter rusty underparts.

In May of 2023, with a lot of help from birding buddies Marty and Jim Herde, I was able to spot and capture a male Red-breasted Nuthatch digging a nest in a dead tree near the Mt Lemmon SkyCenter.  The males will often dig out up to 4 nests, and let their mate pick the nest she wants!  In this case, the female passed on this nest, which was then occupied by a pair of Pygmy Nuthatches a few weeks later. (More on this as the post progresses, keep reading!)

For the post on this sequence of events, with some great images of the male blowing wood chips to the wind, see Spring Nesting 2023, Part 2  . . ., or click on the image above. 

Next, White, Brown, and Pygmy! 


White-breasted Nuthatch

White-breasted Nuthatches eat mainly insects, as well as seeds and nuts. The species gets its "nuthatch" name from gathering large nuts that are too big to eat, then jamming them into tree bark, and "hatching" out the insides for consumption. They are black, gray and white, with a white breast that extends above the eye. The black cap is grayer in the female.

The bird above could be a female, caught in Madera Canyon in January of 2021. She appears to have a fuzzy caterpillar in her bill. 

Below, perhaps a male, caught in Hereford in January of 2017. Nuthatches will climb down trees head first foraging for insects. It is thought that climbing down a tree from top to bottom gives the bird a view of insects other birds may have missed when going from the base to the top (Ref: Woodland Woman).

Brown-headed Nuthatch

Brown-headed Nuthatches are the southern cousins of the other three, social birds traveling in noisy family groups throughout the southeast. See the range map to the right. They make their year round home in pine forests, eating insects and nesting in dead trees. Like other nuthatches, in cold months they will eat seeds mostly from pine cones.

​They have a brown cap, blue-gray back, and whitish underparts.

The photograph below was captured toward the northern part of their range in Cape May, New Jersey, October 2021.

Pygmy Nuthatches live year round in long-needled pine forests, primarily ponderosa pines, in the western U.S. They are cavity nesters, usually breeding in large groups in forests not affected by logging or dead wood removal. They are one of the few songbirds in North America that breed cooperatively, with a third of breeding pairs having 1-3 male helpers, often progeny or other relatives. During the winter, family groups will flock with other family groups, with up to 150 birds roosting together in one cavity in formations of squares, oblongs, triangles, diamonds, wedges, and tiers. 
Picture
The Pygmy Nuthatch has been the subject of extensive research. For more, see All About Birds, or Birds of the World.

The two photographs above and one below were captured on the Meadow Trail at ~9000 feet in July of 2021. Here an adult Pygmy Nuthatch, male or female, is lunching on a Lady Bug.

Below a female is showing mating behavior next to a nest on the Meadow Trail in 2023. This is the same nest dug out by the Red-breasted Nuthatch shown earlier in this post (see, I told you to keep reading!). For more on the Pygmy's mating behavior see Spring Nesting 2023: Part 2: At 9000 feet dead trees make great homes!  or click on the image below.

Pygmy Nuthatch vs. Black-headed Grosbeak, "mano-a-mano."

Research on the Pygmy Nuthatch shows that they are very aggressive toward other birds encroaching on their nesting territory. The sequence here was shot adjacent to our cabin in Summerhaven on June 26, 2025, well within the date range for active broods in the communal nests of Pygmy Nuthatches. 

Above, a Black-headed Grosbeak sits on a seed block along with a Pygmy Nuthatch, both are likely in their breeding territory and looking for food. Below the grosbeak makes threatening moves toward the nuthatch. 

All birds are descendants of dinosaurs, and here the grosbeak is doing a very good Tyrannosaurus Rex impersonation!

In the series that follows, the two birds face off, the Pygmy Nuthatch holds his ground, in spite of his much smaller size and smaller bill.

Picture

Picture

Above, if birds could snarl, the grosbeak is clearly snarling!  The nuthatch raises up his wings, and in the frame below, the feathers on his head are raised. 

Picture

Below the grosbeak takes a more aggressive stance, jaws open wide. The nuthatch pulls back, but does not flee. 

Picture

Picture

Above, the nuthatch, crown feathers up, hold his ground, and spreads his jaws slightly. Below, the nuthatch goes on the offensive, putting his bill entirely into the mouth of the grosbeak, with the tip of the grosbeaks bill indenting into the feathers on the head of the nuthatch. 

Picture

Below, detail of the image above. The nuthatch's bill is very sharp, and I suspect the grosbeak feels it! Note that the nuthatch has closed his eyes. 

Picture

Below, both birds pull back. 

Picture

The standoff continues. The frame below is the last frame I shot. I assume the ruckus subsided, since I did not find any stray bird parts on the feeder! 

Picture

During breeding there is intense competition for food (feed yourself and your young) as well as the risk of nest predation. Many smaller bird species will take on larger ones, as we see above, when the stakes are high! 

Let's finish up with a burst of color . . . .

In Closing, a Western Tanager at 9,150 feet!

This Western Tanager was greeting the morning sun on a pine branch on the Meadow Trail, close to the Sky Center on June 29th.* 

​Western Tanagers winter in Mexico and Central America and summer on their breeding territories from the Rocky Mountains west to the Pacific Coast and north into Canada, all the way up to Alaska. SE Arizona is in the very southern portion of their breeding range, and I would guess a lot warmer than Alaska! 

*My thanks to Jim Herde for spotting this male.
Picture
​Western Tanagers are member of the Cardinal family. Males are bright yellow with an orange-red head and black wings, back and tail.  Females are a somewhat more muted yellow-green and black.  
​
Most red birds get their red color  from dietary plant pigments known as carotenoids. However, the Western Tanager gets its scarlet from a rare pigment called rhodoxanthin, also acquired in the diet probably from insects.  

Western Tanagers live in open woods and eat predominantly insects, especially during breeding season, but are able to shift to fruit in fall and winter.
 They are tree nesters with  the female building the nest.  The male is attentive throughout the breeding cycle sometimes feeding her and sharing the responsibility for chasing away intruders. 

Tanagers are limited to the Western Hemisphere. Most tanager species live in Central and South America, but five species live or wander into the U.S.  In addition to the Western Tanager, we might spot the following four species in the U.S.: 
​​
  • Hepatic Tanager: Winters from Mexico to South America, breeds in Arizona and New Mexico. A regular at the feeders in Madera Canyon. Photograph to the right, Madera Canyon, February 2022.
Picture
  • Summer Tanager: Winters from Mexico to South America, breeds in the U.S. from the Carolinas to SE California, including southern Arizona. Photograph to the right, Cave Creek Canyon, Portal, AZ, April 2021.
Picture
  • Scarlet Tanager: Winters in South America, breeds in the NE U.S. from Minnesota to Maine and into Canada. Not a regular in SE Arizona, although ebird reports sightings scattered throughout the western states, including the Tucson area.  Photograph to the right, Northwest Ohio during spring migration, May 2022.
Picture
  • ​Flame-colored Tanager:  A  year round resident of the mountain forests of Mexico and Central America. eBird reports sightings in SE Arizona in Sierra Vista as well as Portal. I spotted one in the mountains of Panama in March of 2024.​ Photograph to the right, Panama, March 2024.
Picture

Well, it is time to post, July 6, 2025.  Yes, the monsoon did come!  Wednesday saw almost 2 inches of rain in Summerhaven. We are all looking forward to more! 

Stay tuned! 
​Happy trails!
