About These Birds

Heermann's Gull

Heermann's Gull, 46–51 cm, is distinctive — dark grey body, white head (breeding), red bill. Breeds almost entirely on Isla Rasa in the Gulf of California, then disperses north along the Pacific coast to British Columbia. Kleptoparasite; steals fish from Brown Pelicans. Near Threatened; range highly restricted.

White-cheeked Tern

White-cheeked Tern, 32–34 cm, breeds around the Red Sea, Persian Gulf, and Indian Ocean coasts from East Africa to Pakistan. Grey above and below in breeding plumage, white cheek patch below the black cap. Piscivore; plunge-dives in coastal waters. Some movement to winter quarters in East African coasts.
