Adult: head, neck and lower body white, upper body and two wings gray-brown, flight feathers black-brown, under-wing coverts white, tail against the base 2/3 is dark gray, the rest is white. Subadults: light brown replaces white in adults, dark brown replaces grayish brown. Tail is wedge-shaped. Beak and wax membrane gray, bare tarsals and feet light gray. Inhabits shores, trees near water, or rocks. Elegant when soaring or gliding high in the air, flying at an angle with slow, strong wingbeat. It dives into the water to catch surface fish.
