About

Heermann's gull is a gull resident in the United States, Mexico and extreme southwestern British Columbia, nearly all nesting on Isla Rasa in the Gulf of California. They are usually found near shores or well out to sea, very rarely inland. The species is named after Adolphus Lewis Heermann, nineteenth-century explorer and naturalist.

Fun Fact

The only known active breeding colony of Heermann's gull in the continental United States is located in Seaside, California, when a small number of gulls were observed nesting on artificial fill islands on Roberts Lake as of 1999.
