The southernmost form (Bay-winged Hawk) remains streaked on underside and paler, streaked head even as adult, and is fairly pale on underside as juvenile.
Distribution
Sonoran desert of the southwest USA and Mexico, Baja Penisula, Gulf Coast from central coastline of Texas southward through Mexico to Chile and Argentina. This species is absent from much of eastern South America
Taxonomy
Subspecies
There are 2 subspecies[1]:
- P. u. harrisi:
- P. u. unicinctus (Bay-winged Hawk):
An additional subspecies P. u. superior in Baja California, Arizona, Sonora, and Sinaloa is not generally recognised[2].
Habitat
Sparse woodland and semi-desert, as well as marshes.
Behaviour
Diet
An unusual behavior in its family is team hunting; birds will cooperate in taking prey, often taking perches in what seems like a strategic manner to confuse and herd its prey before one of the group strikes. This allows it to take larger prey such as jackrabbits. Teams can comprise 2 to 6 individuals. Other prey includes rodents, lizards, and birds.
