SPECIES INFO

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 huge 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.

Little Auk in winter plumage

This is the only Atlantic auk of its size, half the size of the Atlantic Puffin at 19-21 cm in length, with a 34-38 cm wingspan. Adult birds are black on the head, neck, back and wings with white underparts. The bill is very short and stubby. They have a small rounded black tail. The lower face and fore neck become white in winter.

The flight is direct, with fast whirring wing beats due to the short wings. These birds forage for food like other auks by swimming underwater. They mainly eat crustaceans especially copepods, but also other small invertebrates along with small fish. They collect in large swarms before leaving their breeding rocks to head out to sea for food as well as when they return.

Little Auks on Svalbard

Little Auks produce a variety of twitters and cackling calls at the breeding colonies, but are silent at sea.

Large numbers of Little Auks have been killed in several oil-spill incidents. Over-fishing has little effect, because their prey is mainly crustaceans, but climate changes (warming) in Southern Greenland and Iceland seems to be the reason for the decreasing populations there. The Glaucous Gull and the Arctic Fox are the main predators on Little Auks, and in some cases the Polar Bear has also been reported to feed on their eggs (Isaksen & Gavrilo 2000).
