About These Birds

Caspian Gull

Caspian Gull, 56–68 cm, breeds around the Black Sea and Caspian Sea, wintering to the Middle East and East Africa. Long parallel-sided bill, rounded head, pale eye with yellowish orbital ring, pinkish legs. Omnivore; scavenges at landfills and forages in agricultural fields. Partially migratory.

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.
