126 R.E.Johnson 1968 Journal Nov. 21 Bodie, Mono Co., Calif. (cont.) aggressive interactions. By 3:50 PM they had worked there way down the cliff almost out of my vision. Four flew to the shaft & entered quietly. I could not locate the others, perhaps they had entered just previously. At 3:55 pm a Horned Lark flew se overhead. No additional rosy finches were seen at the shaft by 4:10 PM. The only groups to arrive had been the 2:00 group so far as I could tell. Their arrival had been announced by considerable chirping. There were occasional bursts of chirping thereafter but it was mostly quiet. A chipmunk & 2 Pikas were seen in the rocks/lides and a Sparrow Hawk had sat near the finches for 5 minutes shortly after the finches arrived. At shaft 4 Marr recorded the following notes: 2:30 PM - 3 birds disappear over tailings hill directly back of me [north]. Light, high chirp, scalloped flight. 2:35 PM - about 70 to 80 birds, half went into hole, rest disappeared over tailing. In 3 minutes flock came out. Most went over tailings but 10 or so stayed in and around hole. More arrive, 5 to 8 more at 2:37 PM, go in hole. Very nervous. They pop in and out frequently. 2:40 PM About descended rapidly into hole from about 10 ft. of ground - not cautious. Look like a new group, as old group of 20 or so had just left. Another flock arrives from in front (toward Sierras) [sw], fights on down valley and appears to stop.
