[edit] Etymology
The Abert's squirrel is named after Colonel John James Abert, an American naturalist and military officer who headed the Corps of Topographical Engineers and organized the effort to map the American West in the 1800s.
[edit] Taxonomy
A number of subspecies have been described including the Kaibab Squirrel.
[edit] Physical characteristics
Abert's squirrels are 46–58 cm long with a tail of 19–25 cm.
[edit] Biology and behavior
The Abert's squirrel typically builds its nest in the branches of the ponderosa pine in groups of twigs infected with mistletoe. They are strictly diurnal. The Abert's squirrel does not store its food like other North American squirrels.
[edit] Diet
The vast majority of the squirrel's diet consists of parts of the ponderosa pine. Feeding on the tree's seeds and buds in the warmer months, it depends on the inner bark of the tree for nourishment in the wintertime. Consequently, Abert's squirrels are found in coniferous forests with large populations of ponderosa pines.
