About the Cooper's Hawk

The Cooper's Hawk is the bird-feeder hawk — a crow-sized, short-winged, long-tailed raptor built to thread through branches at full speed in pursuit of songbirds. Adults are handsome: blue-gray above with a black cap, rusty barring below, and a banded tail rounded at the tip. Once a shy forest bird, the Cooper's has moved to town, and Michigan neighborhoods now host more of them than the deep woods do.

A Cooper's hunting run is explosive ambush — a gray blur around the hedge, a puff of feathers, and silence at the feeder for the next half hour. It can feel brutal, but it's native predator and native prey, a food chain functioning in plain view.


Diet

Small to medium birds

Medium-sized birds — doves, starlings, robins, jays — taken in high-speed ambush, plus chipmunks and squirrels. The feet do the killing; the long tail does the steering.

Questions birders ask

A hawk is picking off birds at my feeder — should I do something?

If it bothers you, take feeders down for a week or two; the hawk moves on and the songbirds return quickly. It's a natural predation, and the hawk is federally protected either way.

How do I identify a Cooper's Hawk?

Crow-sized with short rounded wings, a long banded tail with a rounded tip, and adult blue-gray back with rusty-barred chest. The very similar Sharp-shinned Hawk is jay-sized with a squared tail — size is the quickest field mark.

Why do Cooper's Hawks do so well in cities?

Suburbs concentrate their prey (doves, starlings, feeder birds) and offer plenty of nest trees. Studies show urban Cooper's Hawks now often outnumber and out-produce their forest cousins.

Do Cooper's Hawks stay in Michigan all winter?

Yes — Cooper's Hawks are present in Michigan in every month of the year. Numbers stay fairly steady from month to month. Birds are easier to detect in the breeding season, when they are singing and displaying, so a quiet winter month can feel emptier than the population actually is.

How do I tell a juvenile Cooper's Hawk?

Juveniles are brown above with crisp brown streaking on a white breast and yellow eyes, quite unlike the adult's blue-gray back, rusty barring, and red eyes. Most backyard 'hawk at the feeder' sightings in late summer and fall involve these young birds.
