Identification of the large pink-footed gulls (Herring, Thayer's, Glaucous-winged, Western and Glaucous) along the West Coast is difficult.

They are a common migrant and winter visitor offshore. Moderate numbers also winter in the Willamette Valley, concentrating with other gulls and landfills and other food sources and are most common around Portland and Eugene.
