The little auk, or dovekie (Alle alle), is a small auk, the only member of the genus Alle. It breeds on islands in the high Arctic. There are two subspecies: A. a. alle breeds in Greenland, Iceland, Novaya Zemlya and Spitsbergen, and A. a. polaris on Franz Josef Land.
Their breeding habitat is coastal mountainsides, where they have large colonies. They nest in crevices or beneath large rocks, usually laying just one egg. They move south in winter into northern areas of the north Atlantic. Late autumn storms may carry them south of their normal wintering areas, or into the North Sea. The species is also commonly found in the Norwegian Sea. source
