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.

Saunders's Tern, 22–24 cm, is a small coastal tern of the Red Sea, Persian Gulf, and Indian Ocean coasts. Very similar to Little Tern; separated by darker outer primaries and slightly smaller size. Piscivore; hovers and dives in shallow coastal waters and tidal mudflats.
