Range and Habitat

The Cooper's Hawk inhabits most of the United States, Mexico and southern Canada. Except for those residing in the southern portion of their range, the Cooper's Hawk is a migratory bird. They inhabit the forests, preferring the cover of trees to hunt and breed.

Mating and Nesting

The Cooper's Hawk return to the same breeding area year after year, but they build a new nest in a new site every year. The mated pair will stay together for the season but often change mates the following year.

They build a stick nest high in the trees, usually in the crotch of a deciduous tree. The clutch is usually two to five eggs and are incubated for 30 to 36 days. The hatchings are small and covered with white down. The female broods while her mate hunts. The hatchings fledge around four weeks of age but return to the nest to be fed for another four weeks. The young reach breeding age the following year.

The Cooper's Hawk is often referred to as The Chicken Hawk. He's not a popular bird with the farmers.

Amazon.com Review
Few people, writes Scott Weidensaul, are apathetic toward raptors. Once you've seen a hawk or a falcon or an eagle in action, you're likely to take an interest in how these great birds of prey make their homes in the world. The Weidensaul's encyclopedic guidebook to the world's principal raptor species, well illustrated with photographs, maps, and charts and full of detailed information, is an ideal companion.
