About These Birds

Common Gull

Common Gull, 40–46 cm, is a medium-sized gull breeding across boreal Europe and Asia, wintering on Atlantic and Pacific coasts. Smaller and more dove-like than Herring Gull; yellow-green bill without red spot. Omnivore; follows ploughs, forages on shorelines and playing 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.
