17.5–39.5 in long (45–100 cm) — a medium to large raptor (typical for the family)
Habitat
Open country, woodlands, cliffs and wetlands, hunting from the air or a high perch.
Diet
Live prey — small mammals, birds, reptiles, fish and large insects (carrion for vultures).
Range
Recorded on 405 Breeding Bird Survey routes across 25 states, most concentrated in the Northern Rockies.
Family
