About These Birds
Iceland Gull
Iceland Gull, 50–64 cm, breeds in Greenland and winters on both sides of the North Atlantic to Great Lakes. White wing tips (like Glaucous Gull but considerably smaller), pink orbital ring. Omnivore; scavenges at harbours and landfills in winter. Two subspecies often treated as separate species.
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.
