The Common Murre is a black-and-white auk with a long pointed bill and an upright posture on land. It spends most of the year at sea and dives for fish using its wings for propulsion. Breeding takes place in dense colonies on narrow cliff ledges. A single egg is laid directly on bare rock rather than in a nest. The pointed egg tends to roll in a circle instead of moving straight toward the cliff edge.
Locations where this species is supported by a dated first record, an unambiguous single-place outing or a reviewed assignment.
