Rewstore 1947 Journal 26. Sept. 11 2 mi. N, McKittile, 700 ft., Kern County, California. Slewed until after 4 p.m. Set out 107 traps in the area to the north of camp where the Atriplex is taller. The soil looser & the grass less plentiful. Ran 30 traps about 8:30 pm - yield 1 Onychomys & 2 Dipos. Sept. 12. Traps killed a total of 19 mammals including the 3 found the night before. There included the 9 slewed plus 4 Dipodomys nitiditoides (1♂ + 3♀ imm) and 6 D. lemmannus (3♀ 3♂). Hunted til 8 a.m. missing many thrashers and 2 Sage Sparrows. Both species are in song. The latter reminds me of a meadowlark some what although it is not so loud it has more of a sparrow quality. Also saw killdeer, Red tail, hawks, alder flycatcher. Slewed until 4 or so when Dan McKittllan & son, Carl Jurrissmann & Carl & Mary Kopord showed up. Set out 104 traps before dinner & after dinner drove the road from McKittle almost to Buttonwillow & back in a triangle looking for snakes but found none. Had beer & hamburgers in town & came back to camp about 9:45. Sowed over 15 traps or so [illegible]. Sept. 13 Counter trap line - besides 2 Perognathus slewed got 1 Neithos. (♀ imm.), 2 Peromyscus maniculatus [1♂ + 1♀ & 4-17mm. embryo] 4 Dipodomys lemannus [2 adult imm ♂ and 1 mm. ♀ in embryo] and 1 D. nitiditoides [1 adult ♀ no embryo]. This is the only place so far where the dipos have been breeding. Both species have the testes of the ♂s in the scrotum in most cases and some of the others have found embryos. Both Dipos and Perognathus have black grass seeds almost exclusively in their cheek pouches. (Collected a sample of the glass and also 2 of Atriplex this morning.
