Abert's squirrel or the tassel-eared squirrel is a tree squirrel in the genus Sciurus native to the southern Rocky Mountains from the United States to the northern Sierra Madre Occidental of Mexico, with concentrations found in Arizona, New Mexico, and southwestern Colorado. It is closely associated with, and largely confined to, mature ponderosa pine forests. It is named in honor of the American naturalist John James Abert; nine subspecies are recognised. It is recognizable by its tufted ears, gray color, pale underparts and rufous patch on the lower back. The squirrel feeds on the seeds and cones of the Mexican pinyon and the ponderosa pine when they are available, but will also take fungi, buds, bark, and carrion.

McKay's bunting is a passerine bird in the longspur family Calcariidae. It is most closely related to the snow bunting. Hybrids between the two species have been observed, leading some authorities to treat McKay's as a subspecies of 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.
