hierarchical_section_title: List of mammals of New England / Rodents, order Rodentia / Squirrels, chipmunks, and marmots, family Sciuridae
context_page_description: There are 7 orders, 17 families, 40 genera, and 60 species represented among the mammals of New England. If extirpated, coastal, introduced, and accidental species are included these numbers increase to 8 orders, 26 families, 67 genera, and 105 species. The region includes the U.S. states of Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  The makeup and distribution of the mammals in New England are largely the result of the Last Glacial Maximum when the Laurentide Ice Sheet covered virtually the entire region. Recolonization of the area appears to have occurred from one or a few southern glacial refugia. This is in contrast to the multiple glacial refugia present throughout the American West. As a consequence of both the recent uninhabitability and the few sources of recolonization, species diversity for some taxa in parts of New England are lower than in similar areas in other parts of North America. Chipmunks and ground squirrels are exemplars of this situation. New England has one species of each, but numerous locations west of the Rocky Mountains host several species.
  Habitat varies throughout the region.
context_section_description: Eastern chipmunk, Tamias striatus
  Distribution: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  Subspecies: Tamias striatus lysteri (Maine, New Hampshire, Vermont, most of Massachusetts, northeastern Connecticut, and northern Rhode Island) and Tamias striatus fisheri (extreme southern Massachusetts, southern and central Connecticut, southern Rhode Island) according to Hall (1981). Whitaker and Hamilton (1998) argue that both T. s. lysteri and T. s. fisheri are not valid subspecies and should be synonymized with T. s. striatus. Thorrington and Hoffman (2005), however, recognize both T. s. lysteri and T. s. fisheri as valid subspecies.
  Woodchuck, Marmota monax
  Distribution: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  Subspecies: Marmota monax canadensis (northern Maine, northern Vermont), Marmota monax rufescens (extreme western Maine, northern and southwestern New Hampshire, north central and southern Vermont, western Massachusetts, and southwestern Connecticut)), and Marmota monax preblorum (central and southern Maine, central and southeastern New Hampshire, west central Vermont, eastern Massachusetts, northwestern Connecticut, and Rhode Island) according to Hall (1981). Whitaker and Hamilton (1998) argue that M. m. canadensis and M. m. rufescens, and M. m. preblorum are not valid subspecies and should be synonymized with M. m. monax. Thorrington and Hoffman (2005), however, recognize M. m. canadensis and M. m. rufescens, but not M. m. preblorum, as valid subspecies.
  Eastern gray squirrel, Sciurus carolinensis
  Distribution: Central and southern Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  Subspecies: Sciurus carolinensis pennsylvanicus according to Hall (1981) and Thorrington and Hoffman (2005). Whitaker and Hamilton (1998) do not recognize S. c. pennsylvanicus as distinct from Sciurus carolinensis.
  Fox squirrel, Sciurus niger (extirpated or vagrant?)
  Distribution: Formerly western Connecticut. May be vagrant in western Vermont and western Massachusetts.
  American red squirrel, Tamiasciurus hudsonicus
  Distribution: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  Subspecies: Tamiasciurus hudsonicus gymnicus (Maine, all but southeasternmost New Hampshire, central and western Vermont) and Tamiasciurus hudsonicus loquax (western Vermont, Massachusetts, Connecticut, and Rhode Island) according to Hall (1981). Whitaker and Hamilton (1998) argue that both T. h. gymnicus and T. h. loquax are not valid subspecies and should be synonymized with T. h. hudsonicus. Thorrington and Hoffman (2005), however, recognize both T. h. gymnicus and T. h. loquax as valid subspecies.
  Northern flying squirrel, Glaucomys sabrinus
  Distribution: Maine, New Hampshire, Vermont, western and central Massachusetts, and northwestern Connecticut.
  Subspecies: Glaucomys sabrinus macrotis according to Hall (1981) and Thorrington and Hoffman (2005). Whitaker and Hamilton (1998) do not recognize G. s. macrotis as distinct from G. s. sabrinus.
  Southern flying squirrel, Glaucomys volans
  Distribution: Southern Maine, all but northernmost New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island.
  Subspecies: Glaucomys volans volans according to Hall (1981) and Whitaker and Hamilton (1998).
