Gulls and Terns
LaridaeCharadriiformes
Description
The family Laridae is made up of birds closely associated with water. Distributed throughout the world, representatives of this family nest on every continent, including Antarctica. Most are long-lived birds, many of which do not breed until they are three or four years old. Most are colony nesters and nest on the ground. Clutch size is generally small, varying from one to four eggs. Both parents incubate the eggs and help feed the young. The young typically hatch covered with down and stay in the nest for a few days, after which they leave the nest but stay nearby. Most, especially in Washington, raise a single brood a year. This group is known for its elaborate displays in the air and on the ground.
The Washington representatives of this family can be split into two groups, or subfamilies. The adaptable gulls are the most familiar. Sociable in all seasons, they are mainly coastal, but a number of species also nest inland. Many—but not all—are found around people. Gulls have highly variable foraging techniques and diets. Terns forage in flight, swooping to catch fish or insects. They dive headfirst into the water for fish. Although they are likely to be near water, they spend less time swimming than gulls.
