About These Birds

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.

Spectacled Guillemot

Spectacled Guillemot, 36–38 cm, breeds on rocky coasts and sea cliffs of the western North Pacific from Kamchatka to Japan. Sooty black with white spectacle patches around the eye; red feet. Coastal diver; feeds on fish and crustaceans near rocky reefs. Sedentary; stays close to breeding coast year-round.
