The Cooper's Hawk (Accipiter cooperii) is a medium-sized hawk that's very common at feeders. The one in our yard last year liked to sit on the fence right next to the tree where I have the finch socks.
Cooper's Hawks live year-round across the continental United States. Western birds are smaller than their eastern counterparts.
It's a crow-sized long-legged hawk that looks like its wearing pantaloons, with a long barred tail. Adults have red or orange eyes; juveniles have yellow eyes. As with many birds of prey, the female is about 1/3 larger than the male. Wings and tails are dark brown, underparts buffy with dark bars. Chest and pantaloons have reddish bars.
As you might suspect from their prevalence at feeders, the Cooper's Hawk feeds mainly on small songbirds, with some rodents added into the mix.
