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.
Marbled Murrelet
Marbled Murrelet, 24–25 cm, nests on the mossy branches of old-growth forest in western North America — one of the few seabirds to nest miles inland without excavating a burrow. Threatened; dependent on old-growth Douglas-fir and redwood. Piscivore; dives for sand lance near shore. Endangered.
