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.
Ancient Murrelet
Ancient Murrelet, 24–27 cm, breeds in burrows on North Pacific islands from British Columbia to Japan. Black hood, grey back, white underparts with yellow bill. Nocturnal at colonies to avoid predators. Chicks lead-march to sea within days of hatching — abandoning the nest very early. Planktivore and piscivore.
