About These Birds

Kittlitz's Murrelet, 23–25 cm, is an enigmatic auk that nests on rocky tundra above the tree line in Alaska and eastern Russia, often near glaciers. Mottled brown in summer, white in winter. Critically dependent on glacial outwash for foraging; Vulnerable as glaciers recede. Piscivore.
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.
