Large, pale-chested Buteo with

on sides. Wings dark brown with Greater secondary coverts edged in rust. Face
pale with rusty line running behind the eye and joined in back of the head,
whitish eyebrow stripe and rusty-streaked crown. Mouthparts yellowish, and noticeable wide
gape at mouth. Undertail pattern pale
with dark brown bars, especially towards tip. |

Similar species: |
Red-tailed
does not have feathered tarsi, also averages smaller. Wide gape at mouth is diagnostic for
Ferruginous. When in flight, white
wing panels and tail pattern eliminate Red-tailed. White-tailed Hawk has smaller feet, longer
primary projection and lack “mass” of Ferruginous. White-tailed does not exhibit white panels
in the primaries and secondaries. |
