About These Birds
Parakeet Auklet
Parakeet Auklet, 23–25 cm, breeds on rocky islands and cliffs of the Bering Sea and North Pacific. Upturned bright orange-red bill, white facial plume. Unlike most auklets, feeds on jellyfish, medusae, and crustaceans rather than euphausiids. Winters far offshore in the North Pacific.
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.
