ABERT SQUIRREL (Sciurus aberti ferreus)
A large, heavy-bodied tree squirrel with a long, bushy tail. Has 3 distinct color phases; gray, dark brown, and black, all of which are common in the Park. Has long ear-tufts which are shed in the spring and grown out again by fall. Total length 20 inches.
Of the two kinds of tree squirrels in the Park, the aristocratic-appearing abert or tufted-ear squirrel is predominant in the montane or yellow pine valleys and ridges. They feed on the fine branches of yellow pine and on pine cone seeds. Their large, bulky nests of twigs and pine needles are placed high in the trees and are difficult to locate.
