About These Birds
Least Auklet
Least Auklet, 15–16 cm, is the smallest auk, breeding in immense colonies (millions) on rocky Aleutian and Bering Sea islands. Dark above, streaked white below; a tiny white plume above the eye. Planktivore; sieves copepods and euphausiids at sea. Makes loud buzzing display choruses at colony.
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.
