About These Birds
Crested Auklet

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.
