North and Middle America. There are many races (twelve) but the species breeds from central Alaska, the Yukon, and the Northwest Territories east to southern Quebec and the Maritime Provinces of Canada, and south to Florida, the West Indies, and Central America. In much of the USA the species is resident but the Canadian population moves southwards.
There is a specimen in the Natural History Museum, Tring (BMNH 19184.108.40.20688) said to have been obtained in Kirkwall. Orkney, on 16 March 1919. The identification is accepted, but the stated origin is doubtful. Presumed or confirmed escapes reported from Northumberland, East Yorkshire, Suffolk, Hants, Manchester, Durham, Notts and Norfolk. Has bred but hybridisation with Common Buzzard is frequent. The most recent recorded attempt (with Common Buzzard) was in 2006 in Nottinghamshire.
