Is it a “Sharpie” or a ”Coop”?
Both Cooper’s Hawks and Sharp-shinned Hawks are found throughout most of North America and often visit our yards in search of a warm meal.
Both species are frustratingly similar in appearance. Both birds have slate-grey backs and barred rust-colored chests with long banded tails and relatively short rounded wings. The major discernible difference between them is size. A “Sharpie” is a little larger than a robin; a “Coop” is about the size of a crow. To further complicate matters, in each species the female is notably larger than the male. Thus, a female Sharp-shinned Hawk can be as nearly as large as a small male Cooper’s Hawk.
The most reliable field mark may be the tail, which is rounder in the Cooper’s (think “oo” as in Cooper) and squared off (think “s” for Sharp-shinned and squared). Eye placement may also help – eyes appear more forward in the “Coop” than in the “Sharpie”.
