Parabuteo unicinctus is a medium-large bird of prey that breeds from the southwestern United States south to Chile, central Argentina, and Brazil. It contains two subspecies, the Harris's hawk (P. u. harrisi) and the bay-winged hawk (P. u. unicinctus). The species is also occasionally referred to as the dusky hawk and known in Latin America as the peuco. Harris's hawk is notable for its behavior of hunting cooperatively in packs consisting of tolerant groups, while other raptors often hunt alone. Wikipedia →
