Long-distance migrant. Broad-winged Hawks migrate in large flocks or “kettles” that may contain several individuals or thousands, often soaring on thermal air currents. In the fall many of them pass by the northern and western shores of the Great Lakes and then turn southwest to skirt the Gulf of Mexico. Spring migration is more dispersed, though they concentrate along the southern shores of the Great Lakes and in southern Texas. Some subspecies stay year-round on Caribbean islands.
