The Ferruginous Hawk is a charismatic raptor endemic to western North America. Breeding in the western Great Plains, Rocky Mountains, and Great Basin in the US and Canada, the species typically moves south for the winter, with as much as 20% of the population wintering in northcentral and northwestern Mexico. Ferruginous Hawks are variable with both light and dark morphs, though light birds are much more abundant than dark birds. This is a large, long-winged buteo that often holds its wings in a dihedral or modified dihedral when it flies. Ferruginous Hawks feed primarily on small- and medium-sized rodents such as ground-squirrels and rabbits.
