Female Harris’s hawks mate with two males, both of whom contribute food and help raise the young. Sexual dimorphism in this species is pronounced—females are much larger than the males.
As with all birds of prey, Harris’s hawks find prey by using their exceptional vision. Unlike other raptors, however, Harris’s hawks are known to hunt cooperatively, especially in arid areas. This behavior increases the chance of a successful hunt. One bird typically flushes the prey out of hiding and the others pursue it. Harris’s hawks living in the savanna areas of South America behave more like typical raptors and hunt alone.
