Abstract

summarize the status of the Barn Swallow on Herschel Island-Qikiqtaruk, in the Arctic Ocean along the coast of the Yukon Territory, providing evidence that three were of the European subspecies. There are five other records of Hirundo rustica rustica along the Arctic coast of Alaska west to Barrow, but no others for hundreds of miles to both the west and the east. The pattern suggests that these birds reached North America by overshooting their spring migration route on a great circle route nearly over the North Pole.
