Red-tailed hawk [SEP] Distribution and habitat
The red-tailed hawk is one of the most widely distributed of all raptors in the Americas. It occupies the largest breeding range of any diurnal raptor north of the Mexican border, just ahead of the American kestrel ("Falco sparverius"). While the peregrine falcon ("Falco peregrinus") has a greater latitudinal distribution as a nester in North America, its range as a breeding species is far more sporadic and sparse than that of red-tailed hawks. The red-tailed hawk breeds from nearly north-central Alaska, the Yukon, and a considerable portion of the Northwest Territories, there reaching as far as a breeder as Inuvik, Mackenzie river Delta and skirting the southern shores of Great Bear Lake and Great Slave Lake.
