About These Birds
Lesser Black-backed Gull
Lesser Black-backed Gull, 48–56 cm, breeds across Northern Europe and Iceland, undertaking one of the longest migrations of any large gull — to winter quarters in East Africa, India, and the Gulf. Slate-black mantle, yellow legs, yellow bill with red spot. Omnivore; increasingly winters in North America.
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.
