Salt 1947 Journal 5mi E, 4mi S, Shandon, 1175 ft, San Luis Obispo Co., Calif. 21 Aug. Another cold night last night. Woke up to find ground mist in the valley there. Ran trap line after breakfast. Caught a ♂ & ♀ Dipodomys & 2 adult and on imm. Peromyscus maniculatus. Those portions of trap line in bare ground covered only with dried stubble of annuals yielded nothing although there were holes there too. The other plant growth with the Artemisia is a long stemmed Encelia. Skinned for a while then took a run with Mr. McMillan to a canyon on east side of San Juan Valley. Flushed 2 Sage Sparrows but got neither. Collected a Bewick Wren and a Rock Wren in that Canyon. Both species were fairly abundant. Saw about 6 Bewick Wren in one pair of side draws and about 4 Canyon Rock Wrens at the upper end of the side draw where the erosion had made a bank. Skinned some more after lunch; then went out again with McMillan to look for Sage Sparrows. Searched 4 canyons on the east side of valley but again no success. Saw 2 Brown Towhees in one canyon.
