Glaucous Gull

Glaucous Gull
Larus hyperboreus
Gull-like Birds | Family: Gulls and Terns, Laridae

An estimated 5% of the species' North American breeding range lies within the Boreal Forest.



The Glaucous Gull is uncommon south of Canada; it is usually found with flocks of other gulls when it visits the United States. This is one of the most predatory of gulls, capturing and eating auks, plovers, small ducks, ptarmigans, and songbirds as well as lemmings and fish. It is also a scavenger, feeding on garbage, dead animal matter, and even bird droppings.
