Adults weigh approximately 10 kilograms (22 pounds) and have a wingspan up to 2.9 meters. Adults have a bare, orange or yellow-orange head and neck, and a white bill. Both sexes of this species have similar coloration (Brown 1997). Its head and neck are bare of hair or feathers, except on the forehead which is covered with stiff, black feathers. There is a prominent ruff of lanceolate feathers around the neck. The condor's back, wings, tail, and under parts are black. The underwing coverts and axillaries are white. Its bill and feet are gray horn colored, with a small patch of red on the knees (Palmer 2001). Immature condors have a dark head and neck that are covered with gray down. The underwing patch may vary from mottled white to nearly all black. The color of the head and neck turns orange and the underwing patches become white (Brown 1997).
