Verdin
The Verdin is a small and active songbird of the southwest United States and Mexico. In the order Passeriformes (songbirds) it is the only North American member of the penduline-tit family, Remizidae. The bird is gray with a yellow head, and a rufous shoulder patch, not often seen, but visible here, especially in the two frames below. All images captured at Sabino Canyon in December 2015.
