Life Cycle

Red-legged Kittiwake The red-legged kittiwake nests in huge colonies that can include thousands of birds. The red-legged kittiwake male returns to the same nesting site year-after-year. Male and female pairs may mate for more than one season. The nest is cup-shaped and made of moss, seaweed, and mud. The nest is placed on the top or side of a cliff or ledge. The female lays 1-3 eggs. The male and female both incubate the eggs. The chicks hatch in about 27 days. Both parents care for and feed the chicks. The chicks fledge when the are about 40 days old.


Red-legged Kittiwake It is estimated that over 75% of the world's population of red-legged kittiwakes nest on St. George Island in the Pribilof Islands in Alaska. During the breeding season, the ledges of the island are packed with tens of thousands of kittiwakes and other nesting birds.
