Cooper’s and Sharp-shinned Hawks

Cooper’s and Sharp-shinned hawks pose a real ID challenge, even for longtime birders. Throughout the year, there is great variation in plumage and in size for these two species. They look so much alike that no single field mark stands out to help bird watchers easily tell one from the other.

Size is the defining factor, but that’s sometimes hard to judge with a single bird. The rule of thumb is that a Cooper’s Hawk is about the size of an American Crow and the Sharp-shinned Hawk is more the size of a jay.

Below are a few ID guidelines that may help–at least some of the time! Clicking on the bird name will also take you to more information in our Online Bird Guide.
