This gull nests on offshore islands, rocky coastal cliffs, and sometimes in grass on level parts of headlands. It forages in the marine and intertidal environments.

Glaucous-winged gulls eat just about any animal material they find. They take small fish, barnacles, molluscs, sea urchins, bird eggs, carrion and animal waste discarded from fishing boats.

It is rare but regular along the coast and the Columbia River; local and rare in the Willamette Valley. In can be uncommon midwinter at Sauvie Island. Most Glaucous-winged gulls in Oregon nest in the mouth of the Columbia River.
