About These Birds
Little Auk
Little Auk (Dovekie), 17–19 cm, is abundant in the High Arctic, with hundreds of millions breeding in Greenland and Svalbard — one of the world's most numerous seabirds. Tiny, black and white, stubby-billed. Planktivore; dives for copepods. Winters at sea in the North Atlantic, often far offshore.
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.
