Rough legged hawk (Buteo lagopus)
A hawk of the North, the Rough-legged Hawk breeds in Arctic tundra and taiga regions around the northern hemisphere. Both dark and light forms are common, with many birds intermediate between the extremes.
The name “Rough-legged” Hawk refers to the feathered legs. The Rough-legged Hawk, the Ferruginous Hawk, and the Golden Eagle are the only American hawks to have legs feathered all the way to the toes.
