Scientific name: Uria aalge
Nature Stars: 60
About: A medium-sized seabird, about 45cm long. Guillemots are chocolate brown above and white below. In the winter they have white faces. Guillemots nest on ledges on cliffs, in tightly packed colonies. They feed on fish, crustaceans and molluscs, by diving into the sea. At three weeks old the chick plunges into the sea with its father, who will care for it at sea until it is independent - wow!
The other species of guillemot found in the UK is the black guillemot.
How to identify: Guillemots can be told from razorbills as they are brown rather than black above and they have a longer, narrow, all dark bill. Guillemots nest on the narrow ledges on cliffs, while razorbills nest lower down where it is more rocky.
Where: Nests on coastal cliffs. Can be seen around most of our coasts during migration.
Fantastic fact: Guillemot eggs are very narrow and pointed at one end, to stop them rolling off the cliff ledges!
