About These Birds

Least Auklet

Least Auklet, 15–16 cm, is the smallest auk, breeding in immense colonies (millions) on rocky Aleutian and Bering Sea islands. Dark above, streaked white below; a tiny white plume above the eye. Planktivore; sieves copepods and euphausiids at sea. Makes loud buzzing display choruses at colony.

Horned Puffin

Horned Puffin, 36–41 cm, breeds on rocky cliffs and talus slopes of Alaska and the Russian Far East. White face, massive orange-red bill, fleshy dark 'horn' above eye — striking in breeding plumage. Piscivore; dives for capelin, sand lance, and herring. Pelagic in winter across the North Pacific.
