A large eagle with rich brown plumage, wide wings, and seven well-splayed “fingers” at the wingtip. Adults are entirely dark brown; juveniles and immatures at rest show a distinctive wide white band bordered with black on the wing. In flight, this transforms into a white traverse band on the underwing that forms the base of the primary and secondary feathers. Birds take about four years to attain adult plumage. Frequents open grasslands, deserts, scrub, wetlands, and mountains, and is a regular carcass feeder along with vultures.
