Characteristics
 Abert's squirrel is also know as the tassel-eared squirrel. It has long tufts or tassels of fur on its ears. Its fur is gray on the sides, reddish on the back and white on the belly. It has a bushy tail with white fur on the underside. In the summer, its ear tassels may be smaller or they may disappear. Abert's squirrel has long rear paws and strong hind legs. It spends a lot of time in trees and is well-adapted for climbing and leaping from branch to branch.
Range
 Abert's squirrel can be found in the mountainous areas of New Mexico, Colorado, Utah, Arizona and parts of Wyoming and north central Mexico. They are non-territorial squirrels and their home ranges often overlap.
Habitat
Abert's squirrel live in coniferous forests with ponderosa pine trees.
Diet
 Most of the Abert's squirrel's diet is made up of parts of the ponderosa pine. In warm months, it eats the tree's seeds and buds. In the winter, it eats the inner bark of the tree. It sometimes eats mistletoe and fungi.
Unlike other North American squirrels, it doesn't store its food. Its nest is usually built in a ponderosa pine in a group of twigs infected with mistletoe. The nest sits 20-40 feet above the ground and is made with twigs and lined with materials like grass, leaves, feathers, moss and pieces of bark.

Life Cycle
 Mating season can run from late February through early June. During mating season, the female is followed by small groups of males. The males chase the female through the trees for hours at a time. Males and females sometimes fight during mating season. The female usually has only one litter a year with one to five babies in each litter. The babies are born without fur and with their eyes closed. They may start to climb down to the ground when they are about seven weeks old. They are weaned after about 10 weeks.
Behavior
Abert's squirrels are active all year long. They may stay in their nest in very cold weather, only leaving to find food. They are active in the day and sleep in their nests at night.
