The Red-legged Kittiwake breeds on islands in the Bering Sea and is recognizable by its red legs and yellow bill.
It has a white body, dark grey back and upper wings, black wing tips, red legs and a yellow bill.
Red-legged Kittiwakes breed on Buldir and St. George islands in Alaska. Brie Drummond and colleagues used geolocation loggers to compare birds from these colonies over two non-breeding periods, from 2016 to 2018. During early winter, Buldir birds moved west, while St. George birds remained around the Bering Sea and eastern Aleutians for longer.
From January through March, birds from both colonies concentrated south of Kamchatka and east of the Kuril Islands, along the Kuril-Kamchatka Trench and Western Subarctic Gyre. The tracking showed separate early-winter areas followed by a shared late-winter region. The recorded route links two distant breeding colonies to the same part of the North Pacific later in winter.
An extinction-risk assessment has not been added yet.
Birds from Buldir and St. George used separate early-winter regions, then overlapped east of the Kuril Islands from January to March.
