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.
Black Guillemot
Black Guillemot, 30–32 cm, is a compact North Atlantic alcid, distinctive in summer: entirely black with bold white wing patches and vivid red feet. Resident on rocky Arctic and boreal shores year-round; does not undertake long pelagic migrations. Dives to 50 m for blennies and sand eels near shore.
