About These Birds
Marbled Murrelet
Marbled Murrelet, 24–25 cm, nests on the mossy branches of old-growth forest in western North America — one of the few seabirds to nest miles inland without excavating a burrow. Threatened; dependent on old-growth Douglas-fir and redwood. Piscivore; dives for sand lance near shore. Endangered.
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.
