The Harris hawk is an interesting bird. While most raptors are solitary except for mating and migration Harris hawks often live in groups of up to seven birds. These groups consist of both juvenile and adult birds of both sexes. They will often hunt cooperatively also. Harris hawks hunting as a pack are more successful then birds that hunt individually. Hunting in a group allows them to employ different strategies then would be possible for a lone bird, such as having one or two birds chase the prey while others wait ahead in an ambush. It is believed that this cooperative behavior may have developed because of the harsh desert climates where these bird are usually found, such as the south western United States, Mexico as well as parts of Central and South America.
