Red-tailed HawkButeo jamaicensis
18-25" (46-64 cm). W. 4' (1.2 m). A large stocky hawk. Typical light-phase birds have whitish breast and rust-colored tail. Young birds duller, more streaked, lacking rust-colored tail of adult; they are distinguished from Red-shouldered and Swainson's hawks by their stocky build, broader, more rounded wings, and white chest. This species quite variable in color, especially in West, where blackish individuals occur; these usually retain rusty tail.
