The currently accepted scientific name for Abert's squirrel is Sciurus aberti Woodhouse, 1853. [4] Woodhouse had initially described the species as Sciurus dorsalis in 1852, but this name turned out to be preoccupied by Sciurus dorsalis Gray, 1849 (now a subspecies of variegated squirrel S. variegatoides), and thus the present species was renamed.
The number of species in the genus is subject to change. In 2005, Thorington & Hoffman- whose taxonomic interpretation is followed by the IUCN website- accepted 28 species in the genus: [a] Genus Sciurus. Sciurus granatensis. Subgenus Sciurus. Allen's squirrel, Sciurus alleni; Arizona gray squirrel, Sciurus arizonensis
The Kaibab squirrel's most significant source of food is the seeds found within ponderosa pine cones. [5] Young squirrels are born between April and August. In the past the Kaibab squirrel was given species status (Sciurus kaibabensis), but it is now considered a subspecies of the Abert's squirrel (Sciurus aberti). [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.
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]
Squirrels are generally small animals, ranging in size from the African pygmy squirrel and least pygmy squirrel at 10–14 cm (3.9–5.5 in) in total length and just 12–26 g (0.42–0.92 oz) in weight, [8] [9] to the Bhutan giant flying squirrel at up to 1.27 m (4 ft 2 in) in total length, [10] and several marmot species, which can weigh 8 kg ...
