California Chickarees are common locally in the coniferous 

 forests of the Sierra Nevada and other mountains of the north- 

 eastern part of California, from 3,000 feet altitude up nearly to> 

 timber line, but are most common in mixed pine and fir forests. 

 N'Ot known to occur south of the Sierra Nevada. 



The food is quite varied but consists principally of the 

 seeds of conifers, such as fir, big trees, sugar pine and yellow 

 pine, berries, nuts, acorns and chinquapins. Mushrooms and 

 some insects are also eaten. I have caught these Chickarees in 

 meat baited' traps set for other animals. They often store seeds
