This week’s featured animal is the pine squirrel. Nine squirrels call Colorado home: Abert’s, fox, pine, 13-lined, Wyoming ground, rock, spotted ground, white-tailed antelope, and the golden-mantled ground. Of these, the first three are in a category of tree squirrels, which build their nests in cavities, witches’ broom (a dense mass of shoots as a result of a rust disease) or clumps of leaves, pine needles and twigs in trees. Here are five more facts about these cute little tree dwellers.

2. These small squirrels with short bushy tails are in the genus Tamiasciurus, a Greek term that means “hoarder squirrel.”

3. Pine squirrels do not hibernate in winter but rather survive off a cache of pinecones collected throughout the summer and fall. Look for the piles of scales from stripped cones, called middens, at the base of conifer and ponderosa pine trees as an indicator of the squirrel’s existence in the tree.

5. Common in Rocky Mountain National Park, this is the smallest tree squirrel in this region.
