(wingspan: 46’’-54’’) Swainson’s Hawks have a slim body with slightly pointed wings. The adults are white on the chest with a reddish bib and a white throat and face patch. The underside of the wings have white lining and dark flight feathers. Their tail is grayish-brown with black bands. Juveniles are generally buffy in overall color with darker brown markings.
These birds are often spotted on the ground hunting larger insects such as grasshoppers and crickets. They also prey on rodents and other small vertebrates.
From mid-September to mid-October, Swainson’s Hawks leave Colorado to fly down to Argentina. They return the following spring in time for breeding season.
Mating pairs tend to be monogamous and re-use the same nest with a little renovation. They will have two to four eggs per brood and young will fledge the nest about seven weeks after hatch.
