Abert’s Squirrel

The Abert’s Squirrel, Sciurus aberti, is a tree squirrel that is native to the Rocky Mountains from United States to Mexico, with concentrations found in Arizona, New Mexico, and Durango. Abert’s squirrels are found in coniferous forests with large populations of ponderosa pines. They typically build a nest in the branches of the ponderosa pine in groups of twigs infected with mistletoe.

These squirrels are 18 to 23 inches long. They are strictly diurnal. They do not store its food like other North American squirrels. 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.

The Abert’s squirrel is named after Colonel John James Abert, an American naturalist and military officer who lived in the 1800s.
