Majestic adults have blackish-brown body with white head and tail. Several stages of immature plumages aren't quite as majestic, from fully dark brown to messy and mottled with large patches of white. Look especially for white mottling on the belly on immatures. Scavenges and hunts near bodies of water. Soars with wings flat, like a large, dark plank. Head appears large in flight; projects far in front of wings. Surprisingly weak-sounding vocalization is a series of high-pitched whistles.
