The Laughing Gull is not the most efficient fisherman, and often steals food from pelicans or terns after they have made a catch. The Laughing Gull also gets food from man-made sources such as garbage, sewage, refuse from fishing boats, and anything tossed to them by humans. Reproduction The Laughing Gull is a colonial breeder that may nest with other gulls or terns. Nests are found primarily along coastal bays, salt marshes, and estuaries. Sometimes they can be found near agricultural and industrial areas.
Nests are five centimeters high and eight centimeters wide, and are constructed of sticks and grass.
Laughing Gulls have a typical clutch consisting of one to three olive-brown eggs with dark brown spots. The length of incubation is 20 days, and the Laughing Gull takes 35 days to fledge. The Laughing Gull only has one brood per breeding season. Behavior Laughing Gulls are noisy, aggressive, quarrelsome birds who often steal the prey of other birds. They also feed on the eggs and young of other birds, including those of their own kind.
