Swainson's hawk (
Buteo swainsoni), is a large
Buteo hawk of the
Falconiformes, sometimes separated in the
Accipitriformes like its relatives. This
species was named after
William Swainson, a British naturalist. It is colloquially known as the
grasshopper hawk or
locust hawk, as it is very fond of
Acrididae (locusts and grasshoppers) and will voraciously eat these
insects whenever they are available.
