Guillemot
Uria aalge
Common Guillemots nest on narrow cliff ledges in dense, noisy colonies. Adults stand upright and have slim, dark heads with white underparts. They awkwardly shuffle on ledges but are strong, streamlined swimmers at sea. In the Channel Islands, they breed on some of the more rugged cliffs (particularly around Alderney and Sark). Occasionally spotted out at sea from the coast of Lihou.
