Harris hawks have dark brown plumage, with white on the base and tip of the tail and shoulders and thighs that are chestnut-red in colour. Their legs are long and yellow in colour, just like their cere and they have a black beak.
Harris hawks are one of the most social birds of prey, living in in groups that consist of a dominant, mature breeding pair, and their offspring. The males will stay with their parents for a number of years whereas the females will leave to begin their own groups, after approximately a year. The group will hunt work together hunt, carrying out carefully orchestrated hunting techniques.
They not only work together while hunting, but individuals will help with all aspects of raising their younger siblings, from nest building to protection and feeding.
