Iceland Gull

Larus glaucoides

A pale northern gull, about the size of Herring Gull but more graceful and maneuverable in flight. Despite its name, it occurs in Iceland only during the winter. The typical white-winged form nests only in Greenland, while the "Kumlien's" form, with gray in the wingtips, nests in northeastern Canada. Very closely related to Thayer's Gull, and probably should be considered the same species. The "Kumlien's" form seems to intergrade with Thayer's where their nesting ranges come in contact in the Baffin Island region of Arctic Canada.
Conservation status Mostly remote from effects of human activities. Populations apparently stable or perhaps increasing. Numbers wintering in New England seem to have increased during the last century or so.
Family Gulls and Terns
Habitat Coastal, less frequent inland. During most seasons found in coastal regions, both in protected bays and estuaries and well offshore. Some occur in winter on Great Lakes and other large bodies of water inland. Nests on rocky cliffs, mostly in protected bays and fjords rather than on exposed coastline.

Feeding Behavior

Forages in flight by dipping to surface of water to pick up items or by plunging to just below surface; also feeds while swimming or walking.


Eggs

2-3. Buff to olive, blotched with darker brown. Incubation is probably by both sexes; incubation period unknown. Young: Both parents probably feed young. Age of young at fledging not known.


Young

Both parents probably feed young. Age of young at fledging not known.

Diet

Mostly fish. Aside from a variety of small fish, also feeds on mollusks, crustaceans, carrion, berries, seeds. Around colonies of smaller seabirds, may take eggs or young, and often scavenges dead young birds. Also may feed on refuse around garbage dumps, docks, fishing boats.


Nesting

Breeding behavior not well known. Probably does not breed until 4 years old. Nests in colonies, often in same colonies with Black-legged Kittiwakes, sometimes with Glaucous Gulls. In such mixed colonies, Iceland Gulls usually nest higher than kittiwakes, lower than Glaucous Gulls. Nest site is usually on ledge of a cliff facing the sea. Nest (probably built by both sexes) is a bulky mound of grasses, moss, and debris, with a shallow depression at the top.

Migration

Moves short distance south from Arctic breeding range, mostly wintering in coastal eastern Canada (from Labrador south to New England) and around Iceland. Smaller numbers winter to northwestern Europe.
