About These Birds

White-winged Tern

White-winged Tern, 20–23 cm, breeds in wetlands from Eastern Europe to Central Asia and winters in sub-Saharan Africa, South Asia, and Australia. Breeding male: jet-black body contrasting with white wings. Insectivore; dips over marshes and rice paddies. Long-distance migrant.

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.
