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.
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
