Red-shouldered Hawk

A medium-size buteo with rounded wing tips that do not reach the tip of the tail. Adult: brown above with lighter feather edges and some streaking on head. Rufous on the upperwing coverts gives the “red shoulders.” The primaries are barred or checkered black and white, the dark tail has 3 white bands. Underparts are rufous with white barring. Juvenile: mostly brown above, with less rufous on the shoulders than an adult. Undersides are buffy with variable dark streaks, the brown tail has multiple narrow bands. Flight: all ages show a distinct light crescent at the base of the primaries. Soars on flat wings held forward, glides with wings cupped, giving a “hunched” appearance. Wingbeats are quick and shallow, interspersed with quick glides.
