Which hawk is raiding the bird feeder?

Sharp-shinned Hawk
Accipiter striatus

The quick tell

Forget size first - a big female Sharp-shinned overlaps a small male Cooper’s. Look at the head and tail instead. Cooper’s: a big head that juts well ahead of the wings, a dark cap contrasting with a pale nape, and a rounded tail tip with a wide white band. Sharp-shinned: a small, tucked-in head with a full dark hood, pencil-thin legs, and a squared-off tail tip.

Common questions

A hawk killed a bird at my feeder - which was it?

Both accipiters specialize in songbirds and both hunt feeders. Suburban feeder ambushes are increasingly Cooper’s Hawks, which have adapted to towns; Sharp-shinned are a bit more woodland-bound. Check the head projection and tail tip on your photo.

Should I take my feeder down when a hawk shows up?

A one-week pause disperses the songbirds and usually moves the hawk along. It is also normal predation - an accipiter at the feeder is native wildlife doing exactly what it evolved to do.
