Discussion North America's largest accipiter (Buteo-sized). Feeds on medium-sized birds and mammals, caught in agile surprise attacks. In flight, broad, rounded wings and relatively long, broad and barred tail are noticeable. Fanned tail (seen when soaring) looks rounded, with striking white, fluffy undertail coverts. Close view of perched bird reveals differences from appreciably smaller Cooper's: large head and striking pale supercilium, and pale gray (not rufous) underparts. Sexes are similar; female is larger than male.
