The Vermilion Flycatcher is one of 37 species of Tyrant Flycatchers in the Family Tyrannidae, Order Passeriformes. They are regular residents of SE Arizona, with a range well south into Mexico and Central and South America. They are beautiful birds, easy to spot and fun to watch as they feed. The male spends much of his time perched, looking for insects and running a route that often includes one or more perches. The male's bright color and hunting habits make him easy to photograph - although so much red in bright sun is a challenge in post-production processing.
