Crow-sized, with an all-black football-shaped body, this species is unmistakable in breeding plumage. Unique triangular bill is very deep, reaching from the crown to the chin. It is bright orange on outer two-thirds and mostly yellow on the basal third. This colorful bill, the white face, long pale yellow plumes, and bright reddish orange feet are recognizable even at a distance. Young birds and winter adults are more dusky, with a gray face and muted tufts. Sheds some bill sheathing after breeding, leaving a slightly smaller and less brightly colored bill. Immatures have a much thinner bill that is dusky yellow-green, and might be mistaken for a basic-plumaged or immature Rhinoceros Auklet.
Length: 38 (cm) Wingspan: 64 (cm)
