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.
Breeding
They nest in a tree; the clutch consisting of 2–4 eggs which are incubated for 28 days.
