The black guillemot is a small auk that breeds among rocks at the base of cliffs, on lower slopes, or on rocky islands; they tend to be seen in small numbers. Black guillemots eat fish and crustaceans. They dive down from the surface of the water, and swim to catch their prey. Black guillemots have been observed carrying prey in their beaks for over an hour before eating it or feeding their young. Many thousands of black guillemots breed in the UK, scattered along the coast in pairs or small groups. Not moving far between seasons, in winter, you are likely to spot them in their breeding places.
