The southern flying squirrel or the assapan (Glaucomys volans) is one of two species of the genus Glaucomys, the only flying squirrels found in North America (the other is the somewhat larger northern flying squirrel G. sabrinus). It is found in deciduous and mixed woods in the eastern half of North America, from southeastern Canada, to Florida, USA. Disjunct distribution for populations of this species have been recorded in the highlands of Mexico, Guatemala, and Honduras.
