8.0. Sunday 1952. Journal 26 Aug 22. 3 mi S W Tres Piedras, 9,000 ft Rio Arriba Co New Mexico sage disappears once more and the pine and aspen come back! This has nothing to do with exposure because the valley curves around, and faces just one directly south as did the sage patch. I found 2 large fir tree and 1 large Doug fir growing alone among the pines. What this means I don't know. They were both large healthy trees. I followed the dry creek until it hit a fence line about a mile down from the ridge. Then in dense brush along the creek bottom, I saw several bluebirds among the aspens, I acted very flycatcher-like, pursuing flying insects from a perch. Shot a Warbling Vireo from an aspen. I noticed a good many beefer digging on gopher mounds in the grassy valley. Flock of 25+ Chipping Sparrows among the grain + trees. After supper we went down the road towards town after poorwills. We saw a young Porcupine cross the road, and go into a little oak patch at the base of a big pine. We poked him with a stick but no action. Jerry Russell and I shot up several rounds of .38 at bats, probably Eptesicus. No captures. we drove the roads after Poorwills. Saw 3 but no shots. I set out 50 mouse species about 600 yds south of here in heavier brush
