Once our observations at shafts 4 & 5 were over at about 4:05 pm, we explored to the north for additional vertical shafts. Marr found a large one a short ways above the road, i.e. no. of #4. From hole #4 it appeared some birds may have entered this one. I located one with a vertical entrance & a second vertical hole that turned to meet the 1st in 10 ft. Rocks thrown down this shaft brought numerous birds up the shaft. It is clear that there are at least 30 birds in it. All that I could see clearly had the gray cap limited to the top of the head & were chestnut, not black (i.e. they were tephrocotis or dawsoni). This shaft is just to[illegible] the east of a prominent hill top.
