About These Birds

Belcher's Gull

Belcher's Gull, 49–52 cm, is endemic to the Humboldt Current coast of Peru and northern Chile. Black mantle, white body, yellow bill with red and black band. Piscivore and scavenger; closely associated with fishing ports and anchovy-rich upwelling waters. Resident along its narrow coastal range.

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.
