Range and Habitat
Cooper's Hawk: Breeds from southern Canada to southern U.S. Prefers patchy deciduous and mixed forests.
the Cooper's Hawk has a very large range, estimated globally at 8,400,000 square kilometers. It is native to North America, Belize, Colombia, Costa Rica, Honduras, Nicaragua, and Guatemala and has been spotted in Bermuda. This bird prefers forest and shrubland areas and can also reside in urban areas or rural gardens. It has an estimated population of between 100,000 and 1,000,000 individuals. Because there are no signs of significant population decline, this bird does not qualify for inclusion on the IUCN Red List. Cooper's Hawk currently has an evaluation level of Least Concern.
It captures a bird with its feet, and will squeeze it repeatedly to kill it, instead of biting the prey to kill it in the fashion of falcons. It has also been known to drown its prey.
The Cooper’s Hawk was first described in 1828 by Charles Bonaparte, a French naturalist and ornithologist who was the nephew of Napoleon. It was named after William Cooper, who collected the first specimen.
They capture prey from cover or while flying quickly through dense vegetation. This can be dangerous, a recent study found that 23 percent had healed fractures in the bones of the chest, especially of the furcula or wishbone.
A group of hawks has many collective nouns, including a "boil", "knot", "spiraling", "stream", and "tower" of hawks.
