Range and Habitat
Glaucous Gull: Breeds in Alaska and northern Canada. Spends winters along the coast south to California (rarely) and Virginia; rarely found in the Great Lakes and the Gulf coast. Preferred habitats include shores of lakes, rivers, and coast, as well as refuse dumps and sewage outflows.
First- and second-year Glaucous Gulls appear to move farther southward than adults, and most individuals seen in the southern portion of the winter range are immatures.
It is an active predator at seabird nesting colonies. It will walk into colonies and take eggs and chicks left unprotected, and will fly above a foraging arctic fox or person disturbing the colony and take eggs and chicks that are exposed during the disturbance.
