About These Birds
Crested Auklet
Crested Auklet, 23–26 cm, breeds in huge colonies on Aleutian and Bering Sea islands, forming spectacular wheeling flocks. Elaborate forward-curving crest, small orange bill. Males emit a citrus-tangerine scent from nape used in courtship. Planktivore; dives for euphausiids and copepods in icy waters.
Great Auk

Black above, white below with a white oval eye patch; vestigial wings. Spent most of its life at sea; bred colonially on Atlantic islands and rocks.
