Sagehen Creek Field Station, 6400 ft.; 3 mi. NW Robert Mills, Nevada Co., Cal.:t.
18 October may have been made by one of the ones we trapped last night. On the way back to the car, near the junction of the road to the field station and Hwy 89, we saw at least 4 chipmunks - each in a different tree, getting seeds from open Jeffrey Pine cones about 15 m. high. I think they were E. spegazzini.
The time was about 0830. We then ate breakfast, then checked the Longworths we had put in and near the meadow 1/3 mi. E of the field station at about 1000. I found one E. amoenus in one of 6 traps I'd put in the rabbitbrush area adjacent to the meadow - just S of the road. I took the chipmunk back to the field station for student observation. Since Steve Thompson had caught one Dipodomys leptocaudus on the south side of the creek, in full wet grass within a few meters of it, I set 5 Muscaen speciolis there, and reset the 5 Longworths I'd had in the rabbitbrush there, too.
A summary of the total catch of our group follows:
| | # of trapdays | Mammals caught |
|---|---|---|
| Open meadow | 34 | 1 Sorex, 2 Microtus montanus |
| Tallgrass adjacent to station | 8 | 1 Microtus leptocaudus, 2 M. montanus, 1 Sorex |
| Grass under bushy willow | 25 | 4 M. montanus |
| Pines castrensis | 28 | 1 Peromyscus maniculatus, 1 Eutamias amoenus |
| rabbitbrush | 27 | 2 E. amoenus |
| rocky outcrop | 1 | - |
