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.
Long-billed Murrelet
Long-billed Murrelet, 26–28 cm, breeds remarkably far inland in old-growth forests of Siberia, nesting directly on mossy tree branches — no burrow. Sea-going for the rest of the year, wintering off eastern Asian coasts. Piscivore; dives for small fish. Near Threatened; nesting ecology unusual for alcids.
