FREMONT'S CHICKAREE 



SCIURUS FREMONTI (Aud. & Bachm.) 



Sciurus fremonti Aud. & Bachm. Quad. N. Am. III., 1853, p. 237. 



Description — Tail shorter than the body. Ears tufted 

 in winter, but not in summer. Above mixed brown, gray, 

 and pale rusty, the prevalent tint similar to that of the gray 

 squirrel ; beneath bluish white, a dark line along the sides. 

 Eyelids white. Tail entirely black at end, the hairs tipped 

 with light grey; on other parts of the tail a mixture of 

 plumbeous and greyish rusty at the base of the hairs. No 

 rusty visible externally. (Baird.) 



Distribution — ^Mountains of Colorado and the Uinta 

 mountains, Utah, to the southern border of Wyoming. 



Habits — Like the common Northern Red Squirrel, 

 which it greatly resembles in all respects, except color, S. 

 fremonti feeds chiefly upon pine and spruce cones, which 

 are hoarded in large caches at the bases of trees, beneath 

 logs, and among rocks. I have never found it living in a 

 hollow tree, although it may do so occasionally. The nests 

 of pine or spruce needles and fine strips of bark are usually 

 constructed in the fork of a branch well out from the main 

 trunk, at from 20 to 40 feet above the ground in the densest 

 forest. I have found the nest occupied by the squirrels in 

 both summer and winter. This squirrel is not at all shy and 

 may be coaxed to within a few feet by making a nonde-- 

 script "screeping noise." (Gary.)
