The Brunnichs Guillemot (Uria lomvia) is similar to the Common Guillemot. The main difference is a shorter beak with a white beak line and the sides that are whiter. It breeds in big bird colonies in ocean cliffs. No care is taken in the nest making and they lay their eggs on bare rock ledges.
Látrabjarg and other ocean cliffs in the Westfjords are the main nesting places for the Brunnichs Guillemot. There are around 300,000 breeding pairs in Iceland. The Brunnichs Guillemot is one of the species whose numbers have been decreasing in the last decades.
