About These Birds

Glaucous-winged Gull, 56–68 cm, is the common large gull of the North Pacific from Alaska to California. Distinctive pale grey wing tips (not black) give a uniform grey appearance. Omnivore; forages on rocky shores and at harbours. Hybridises with Western, Herring, and Glaucous Gulls.
Aleutian Tern
Aleutian Tern, 32–34 cm, breeds colonially in Alaska and Russian Far East, wintering in Southeast Asian waters — one of the most poorly tracked migrations among seabirds. Dark grey above, white below, black cap with white forehead. Piscivore; dives for small fish. Near Threatened.
