Buteo swainsoni (Swainson's Hawk)

Language: French; Spanish

Wikipedia Abstract

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.
