About These Birds

California Gull

California Gull, 46–55 cm, breeds at inland lakes of western North America and winters on the Pacific coast. Yellow bill with red and black spot, greenish-yellow legs. Omnivore; famous for saving Utah crickets crops in 1848 — commemorated as Utah's state bird. Strongly 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.
