B. Richardson 235 Chipmunk (Eutamia m. tenebris) 14 Forks of the Big & Little Kern Rivers, Sutter Co. Calif. The three specimens skinned today were all shot with the old .12 gauge in the same locality. The habitat was was a canyon with large boulders, much brush (mostly manzaneta) and some trees (Black Oak and Yellow Pine). 15 The only difference I can see in localities when chipmunks are relatively abundant and those where chipmunks as not found is in the presence or absence of manzanita. The largest colony found about 4 mi above camp is moderately vegetated with manzanita while south of that this is none although in my own report the two places seem similar.
