Harris's Hawk (Parabuteo unicinctus) lives in desert scrub across South America, North America. It feeds on small mammals birds. Its conservation status is Least Concern.
Fascinating facts about the Harris's Hawk
- Harris's hawks hunt in cooperative packs of two to six, a rarity among raptors. Their groups use a scouting system where one bird flies ahead, another follows, and the process repeats until prey is located and shared. They also spread around a target and flush it out, often chasing the animal on foot thanks to their long legs. This teamwork raises capture success, with groups of two to four achieving about ten percent higher success per extra bird.
- Within a Harris's hawk group a clear dominance hierarchy exists: the mature female is the top individual, followed by the adult male and then the previous-year's offspring. These hierarchies are maintained in relatively stable groups that usually contain two to seven birds. The social order helps coordinate their cooperative hunting and nest-defence activities, reinforcing the species' unusual group dynamics among raptors.
- A Harris's hawk pack can bring down an adult black-tailed jackrabbit weighing more than 2,000 g. In the north of its range the birds also target desert cottontails, usually about 800 g, using the same cooperative tactics.
- In the wild a Harris's hawk typically lives only ten to twelve years, a relatively short span for a medium-large raptor. When cared for in captivity, individuals have been known to survive far longer, with some reaching twenty-five years of age. This dramatic extension shows how protected conditions and regular feeding can greatly increase their longevity.
- Trained Harris's hawks are now a practical tool for urban pest control, having been released to disperse pigeon roosts in London's Trafalgar Square and on the tennis courts at Wimbledon. Falconers also employ them at airports, resorts, and landfill sites in North America.
