Little Auk
Alle alle (Linnaeus, 1758)
LK
LITAU
6470
Family: Charadriiformes > Alcidae
This diminutive auk, not much larger than a Starling, is a winter visitor to our coastal waters in varying numbers.
The Norwegian archipelago of Svalbard holds around 90% of the world’s breeding Little Auks. Estimates for the world breeding population are difficult to assess but the European estimate of around 80 million individuals gives some insight into the numbers involved.
After the breeding season Little Auks head south to their wintering areas. The northern part of the North Sea is an important wintering location for Little Auks and the birds remain at sea throughout the winter months, only being seen close to shore when driven there by winter storms. Occasional reports of individuals found far inland are associated with particularly rough storms.

Identification
Little Auk identification is often straightforward. The following article may help when identifying Little Auk.
Identifying winter Auks
Summer Auks, in breeding plumage, at the shore or near to their colonies are relatively easy to identify. But in autumn and winter we tend to see them flying rapidly past, far offshore, or bobbing around in heavy seas offering poor views. When you add to this that their distinctive breeding plumage and colouring is lost, winter Auks can be a serious challenge to identify and separate.

DISTRIBUTION
Little Auks are scarce but regular autumn passage migrants and winter visitors, often driven south after strong northerly gales. Most records were from North Sea coastal squares from Shetland south to Kent, though they also occurred along the south coast of England. Little Auks are relatively scarce in west-coast and Irish waters.
