The Red-Tailed Hawk is quite common in southeast Arizona. Easily identifiable by its dark head, light colored breast, light markings on the back as they are perched. The exception is the dark morph that is a solid dark color as you can see below. When they fly the red tail is quite obvious. Almost all Red-Tailed hawks we have seen have been on the top of poles or the cross bars unlike the Swainson's Hawk that seems to like to perch on the wire.

This Red-Tailed Hawk is just about to land on the wire at the insulator.
Even Red-Tailed Hawks have bad hair days.
The white markings on the back of this Red-Tailed Hawk are clearly visible from a distance and one of the ways we identify the mormal morph. From our experience its quite common.
