Range and Habitat
Thayer's Gull: Nests on high rocky cliffs in the Arctic islands and north coast of Northwest Territories. In winter, usually found in bays, meadows, and beaches on the Pacific coast, from central British Columbia to the Baja Peninsula, but occasionally wanders east to the Great Lakes.
The Thayer's Gull has become a more common winter visitor to the Great Lakes and the East Coast, but whether increasing reports are due to eastward movement of the species or to more birders being aware of this rare gull is not known.
Both the common and species names honor ornithologist John Eliot Thayer.
This bird has variously been considered a species of its own, a subspecies of the Herring Gull, a subspecies of the Iceland Gull, and even a hybrid of the two. At the moment, it is treated as a species.
A group of gulls has many collective nouns, including a "flotilla", "gullery", "screech", "scavenging", and "squabble" of gulls.
