R.E. Johnson 1968 March 10 Peavine MTN, Washoe Co., Nevada (cont.) Journal past a road to the rt, clear made of mine dump material & along the east slope of a hill until the road circled right around the hill to a large vertical (hereafter called the "big shaft") mine shaft & mine dump. This is the location where most of the finches had been seen in 1950-54. Some of the birds were collected and are now in the collection at the Univ. of Nevada. Dr. Johnson had estimated that approx. 100 birds roosted in this shaft each night. Though occasional birds had been seen there in the day, the birds were usually absent until approx. 3:30 PM when (coming from the N) they suddenly appeared high overhead & dove directly into the shaft. They He reported that they were hard to drive from the shaft with lights, rocks, etc & this could only be done effectively by dangling a can with rocks in it, down onto the shaft & swinging it from side to side to disturb the finches from their perches. We could see the bottom & sides of the shaft clearly in the 12 noon sunlight & there were no finches. None-the-less we threw rocks down the shaft but we were unable to bring to light any birds. John felt that we would at least hear them rustling about if any had been present. Just north of this shaft a ridge runs north up Peavine MTN. The
