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.
Common Murre
Common Murre, 38–46 cm, is among the most abundant seabirds in the North Atlantic and Pacific. Breeds on cliff ledges in huge colonies; single pear-shaped egg rolls in a circle rather than off the ledge. Piscivore; dives to 180 m for fish. Flies with rapid wingbeats; waddling gait on land.
