The gyrfalcon (Falco rusticolus) is an arctic dwelling species with a holarctic distribution. It is rarely found south of 60 degrees. The majority of the breeding range is found north of 60 degrees while in parts of Eastern Canada it can be found breeding to 55 degrees, mainly along sea coasts. Although gyrfalcons are non-migratory, they will disperse from the breeding range during the winter season, very rarely reaching the northern limit of the United States (Poole 1987; Wheeler and Clark 1995; Cade 1982).
