LIDICKER 1958 on the W side of camp + an excellent flycatcher with a prominent crest (which turned out to be Contopus pertinax). I also sketched a eye cottontail which a missionary had given me. June 30 (cont.) - Dr PM, Marler + I drove N of Mil Drias as far as we could & then walked further. We were looking for San Juan & the trench grass habitat of Xerochryza. We finally found what has to be the spot & explored it thoroughly - interrupted by occasional rain showers. Although we saw lots of Striped Sparrus we saw no Xerochryza. July 1 (cont.) - We went back N of Mil Drias & while Marler walked N to the trench-grass area to record, I set traps along the side of a beautiful canyon on the W side of the bridge over a large rushing stream where we saw a Water Ouzel. The walls of this canyon are covered with quite lush vegetation including Cornus. I set 50 traps on the S side of the stream & 32 on the N. Also saw a Catillus variegatus just N of the bridge. July 2 Catch: Neotoma - 2 Peromyscus sp 2 - 8 (difficile) Sorex - 3
