About These Birds
Little Gull
Little Gull, 25–30 cm, is the world's smallest gull, breeding in Eurasian wetlands and wintering on Atlantic coasts. Breeding adult has a full black hood; underwing is uniformly dark — unique among gulls. Feeds on insects over water in summer, small fish and invertebrates in winter.

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.
