Description
Adapted for sustained, soaring flight, the black-billed gull has a compact body with long wings and a fan-shaped tail to help control movement in strong winds. With typical colouration for a gull, the black-billed gull can be distinguished by its black bill, legs, feet and wing tips, against a background of grey on the wings and back and white on the head, neck, breast, underside and tail (2) (3).
