Both sexes of the Waved Albatross are generally alike, although males are larger than females. Their plumage is mainly grey-brown with pale head and neck, and the back of the neck is tinged yellow. The underwings are white with dark trailing-edge. The bill is large and yellow.
The Waved Albatross is a great flier, gliding for prolonged periods without flapping their wings, particularly in windy conditions. They feed from the surface, usually far out to sea.
