This squirrel is common on the Columbia in pine forests. 

 Feeds chiefly upon the seeds of the pine, and lays up a large 

 quantity of them for winter store, in the hollows of decayed 

 limbs. 



It is very unsuspicious and tame ; more so than Sciurus Jiud- 

 sonicus. Voice remarkably loud and harsh ; may be heard 

 several hundred yards. It is in the habit of nipping off small 

 branches from the summits of the trees, and throwing them 

 down, apparently in sport. I have seen at one time at least a 

 dozen of them engaged in this way, within a short distance. 

 The twigs were falling in every direction, and the loud call was 

 not suspended for a moment. The nest is made of sticks and 

 hair, usually in the hollow of a decayed branch, rarely in the 

 bifurcation of limbs. Has four young at a birth, which remain 

 longer in the nest than the common gray squirrel. 



I have frequently seen this species tamed, and in the pos- 

 session of the Indian boys. They were very lively and playful. —

" This small species was first noticed by Lewis and Clarke, 

 who deposited a specimen in the Philadelphia Museum, where it still 

 exists. I have compared it with a specimen brought by Mr. 

 Townsend, and find them identical. Richardson, who appears 

 not to have seen it, supposes it to be a mere variety of the 

 Sciurus hudsonicus. On the contrary, Mr. Townsend says in 

 in his notes, ' It is evidently a distinct species ; its habits are 

 very different from those of the Sciurus hudsonicus. It frequents 

 the pine trees in the high range of the Rocky Mountains, west of
