About These Birds

Grey-headed Gull

Grey-headed Gull, 39–42 cm, breeds across sub-Saharan Africa and coastal South America. Pale grey hood in breeding plumage, red-orange bill and legs. Omnivore and piscivore; frequents large lakes, rivers, and coasts. Partially migratory, dispersing broadly outside breeding season.

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.
