The Thayer's Gull breeds in the high Arctic of Canada and winters along the northern Pacific Coast. It has become a more common winter visitor to the Great Lakes and the East Coast, but it is unknown whether increasing reports are due to increasingly eastward movement of the species or to more birders being aware of this rare gull.
Calls are loud, clear bugling.
