The Arizona gray squirrel has had no recent expansion or reduction in the size of their range in New Mexico, though there has been some population decline. This is due to habitat loss and the introduction of Abert’s squirrel, which has in some cases outcompeted the Arizona gray squirrel for resources. [6]

With a typical head-and-body length of about 15 cm (5.9 in) and a 12 cm (4.7 in) long tail, dwarf squirrels are relatively small. However, the Neotropical pygmy squirrel, not in this genus, is much smaller than these species, as are certain squirrels in Africa and Asia. Microsciurus species have gray or brown backs, and white bellies.
