About These Birds
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.
Guadalupe Murrelet
Guadalupe Murrelet, 22–24 cm, breeds only on Guadalupe Island off Baja California. Very similar to Scripps's Murrelet but with more extensive white on the face. Critically Endangered; fewer than 1,000 individuals; nesting habitat threatened by feral cats and goats (now being controlled). Piscivore.
