Cooper's Hawk

 

Cooper’s Hawks are a medium-sized hawk with the classic accipiter shape: broad, rounded wings and a very long tail. In Cooper’s Hawks, the head often appears large, the shoulders broad, and the tail rounded.

Adults are steely blue-gray above with warm reddish bars on the underparts and thick dark bands on the tail. Juveniles are brown above and crisply streaked with brown on the upper breast, giving them a somewhat hooded look compared with young Sharp-shinned Hawks' more diffuse streaking.
