| This Accipiter was apparently a reasonably numerous breeding species in the first half of the 20th Century, even nesting toward the coast. However, for whatever reason (DDT?), Cooper's Hawks went into a steep decline in the 1960's-1980's, especially as a breeder. Thankfully, numbers have bounced back since at least 1990, and this formerly uncommon bird is now seen more often than the smaller Sharp-shinned Hawk during the summer and in much of the remainder of the year. This species is more tolerant of humans and suburban habitats, and birds breed in a variety of forests and woodlots, occasionally in cities and towns. At other seasons, like the Sharp-shinned Hawk, it favors a mix of forests or woodlots interspersed with fields and is not normally found inside deep forests. Unlike the Sharp-shinned, Cooper's frequently perch in the open, such as in a tree in a field or on a fencepost.
In 2025, the AOS moved this species and the American Goshawk out of the genus Accipiter to now Astur; so this species is currently named as Astur cooperii. |
