[5] These are medium-sized birds with mainly black plumage in the breeding season, thin dark bills and red legs and feet.

The breeding habitat is rocky shores and islands on the coasts of the northern Atlantic and Pacific Oceans.

They mainly eat fish and crustaceans, also some molluscs, insects and plant material.
