About These Birds
Common Gull-billed Tern
Common Gull-billed Tern, 35–38 cm, wingspan 76–86 cm, has a broad global range across Europe, Asia, the Americas, and Australia. Stout black bill adapted for catching crabs, insects, and small vertebrates — atypically terrestrial for a tern. Summers in marshes and steppes; winters on tropical coasts.
Andean Gull
Andean Gull, 45–48 cm, breeds at high-altitude Andean lakes from Colombia to Argentina, typically above 3000 m. Black hood in breeding plumage; white below with grey mantle. Largely insectivore, following cattle or foraging at lake edges. Partial altitudinal migrant descending to Pacific and Atlantic coasts in winter.
