Swainson's hawk (
Buteo swainsoni), is a large
Buteo hawk in the Accipitriformes order. 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.
