Life Span A banded Harris's hawk lived over 12 years in the wild. Captive birds can live at least 20 years. During winter months they focus on the cooperative hunting of rabbits. Reproduction Pairing is variable, but many times a female will mate with two males. Often several other birds will assist with the hunting and nesting efforts.
Clutch size is two to four white eggs.
The female incubates the eggs for 33-36 days. The primary male, and often the secondary male, are allowed to feed the nestlings along with the alpha female. After 43-49 days, young fledge and fly for the first time. Life Cycle Harris's hawks hunt in early morning and evening hours. Using their excellent eyesight, they scan for prey from a high perch such as a tree or utility pole, or while soaring high above the terrain.
