Editing Harris's hawk (section)

===Hunting===
While most raptors are solitary, only coming together for breeding and migration, Harris's hawks will [[Pack hunter|hunt in cooperative groups]] of two to six. This is believed to be an adaptation to the lack of prey in the desert climate in which they live. In one hunting technique, a small group flies ahead and scouts, then another group member flies ahead and scouts, and this continues until prey is bagged and shared. In another, all the hawks spread around the prey and one bird flushes it out.<ref>{{cite book|author=Cook, William E.|title=''Avian Desert Predators''|year=1997 |publisher=Springer | isbn=978-3-540-59262-4 }}{{page needed|date=April 2018}}</ref> Harris's hawks will often chase prey on foot and are quite fast on the ground; their long legs are adapted for this, whereas most other hawks do not spend as much time on the ground. Groups of Harris's hawks tend to be more successful at capturing prey than lone hawks, with groups of two to four individuals having ~10% higher success rates per extra individual.<ref>{{cite thesis |last1=Dawson |first1=James |year=1988 |title=The cooperative breeding system of the Harris' Hawk in Arizona |url=http://arizona.openrepository.com/arizona/handle/10150/276864 |type=M.S. |publisher=The University of Arizona |access-date=17 November 2017}}</ref>
