Description

Pine squirrels are small tree squirrels with bushy tails, and apart from the members of the genus Sciurus, they are probably the members of the large family Sciuridae that conform most closely to the commonly held idea of what a squirrel looks like and how it behaves. In biological classification, family (Latin: familia, plural familiae) is 1) a rank or 2) a taxon in that rank. ... Genera Many: see text. ...

In southeastern Arizona there is a relict population of T. hudsonicus considered sufficiently distinct to be awarded sub-species status, T. hudsonicus grahamenis, the Mount Graham Pine Squirrel, reduced to a few hundred members on the Madrean sky islands conifer forests at higher, cooler altitudes. They are the southernmost of the entire species, left stranded when desertification reduced the area of conifer forest that existed in glacial times. Some authors treat the Mount Graham Pine Squirrel as a distinct species, T. grahamensis. The Madrean sky islands are a complex of small mountain ranges in southern Arizona and New Mexico which are home to enclaves of Madrean pine-oak woodlands. ...

The name Tamiasciurus comes from the Latin for "hoarder squirrel".
