About These Birds
Slender-billed Gull
Slender-billed Gull, 37–40 cm, breeds in Mediterranean and Black Sea saltmarshes and lagoons, wintering on West African coasts. Distinctive long slender bill gives a front-heavy profile; white head lacking hood, pinkish-white underparts. Feeds on fish and invertebrates in shallow coastal waters.
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.
