Open encyclopedia reference
McKay's bunting (Plectrophenax hyperboreus) is a passerine bird in the longspur family Calcariidae. It is most closely related to the snow bunting (P. nivalis). Hybrids between the two species have been observed, leading some authorities to treat McKay's as a subspecies of the snow bunting. As the Plectrophenax buntings are nested within the Calcarius clade, their closest relatives are the longspurs. McKay's bunting breeds on two islands in the Bering Sea, St. Matthew and Hall islands, and winters on the western coast of the U.S. state of Alaska.
