Kittiwake - Rissa Tridactyla
Juvenile
Yorks
Kittiwakes are coastal breeding birds ranging in the North Pacific, North Atlantic, and Arctic oceans. They form large, dense, noisy colonies during the summer reproductive period, often sharing habitat with murres. They are the only gull species that are exclusively cliff-nesting. A colony of kittiwakes living in Newcastle upon Tyne and Gateshead in the north east of England has made homes on both the Tyne Bridge and Baltic Centre for Contemporary Art. This colony is notable because it is the furthest inland colony of kittiwakes in the world.
The black-legged kittiwake is one of the most numerous of seabirds. Breeding colonies can be found in the Pacific from the Kuril Islands, around the coast of the Sea of Okhotsk throughout the Bering Sea and the Aleutian Islands to southeast Alaska, and in the Atlantic from the Gulf of St. Lawrence through Greenland and the coast of Ireland down to Portugal, as well as in the high Arctic islands. In the winter, the range extends further south and out to sea.
In sharp contrast, the red-legged kittiwake has a very limited range in the Bering Sea, breeding only on the Pribilof, Bogoslof and Buldir islands in the United States, and the Commander Islands in Russia. On these islands, it shares some of the same cliff habitat as the black-legged kittiwake, though there is some localized segregation between the species on given cliffs.
