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.
Black Guillemot
Black Guillemot, 30–32 cm, is a compact North Atlantic alcid, distinctive in summer: entirely black with bold white wing patches and vivid red feet. Resident on rocky Arctic and boreal shores year-round; does not undertake long pelagic migrations. Dives to 50 m for blennies and sand eels near shore.
