What is the ferruginous hawk?
The ferruginous hawk (Buteo regalis) is a large bird of prey and belongs to the broad-winged buteo hawks. An old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk (B. lagopus).
The generic name buteo is Latin for 'buzzard'. The specific epithet regalis is Latin for 'royal' (from rex, regis, 'king'). The common name 'ferruginous' means 'rust-colored' or 'reddish-brown'.
This species is a large, broad-winged hawk of the open, arid grasslands, prairie and bush steppe country; it is endemic to the interior parts of North America. It is used as a falconry bird in its native ranges.
