Journal 52 R.E. Johnson 1967 July 2 Mt. Thielsen, east boundary of Douglas Co., Oregon (cont.) a White-bark Pine, one of a number fringing a cliff overlooking the floor of the cirque. Naturally the bird fell all the way to the bottom & lit in a stream. Only one other rosy finch was heard during the 2 hours I was in the cirque, but the cirque is so large I couldn't "hear into" all parts of it. Just prior to returning down the trail to Diamond Lake, I attempted to locate a pair of finches I had heard earlier in the day. These were located on cliffs se of the trail after it turns straight up the mtn on loose rock. Unfortunately I did not have my notebook with me to record the details, but I apparently was dealing with a pair of birds, but they foaled me into watching the wrong suspected nest location for 2 hours. A bird did exit this spot (hole) at least once, but when I got higher (at 8:30 PM) I found that the hole extended through the cliff (2 openings) & there was no nest inside. While I was present in the area the male(?) sang a long series of chirps about every 15 min., usually from a rock prominence. Once a rosy finch was heard making an entirely new sound with the cadence of a White-tailed Ptarmigan. Drove back to Crater Lake for the night July 3 Diamond Crater Lake Nat. Park to Steens Mtns, Harney Co., Oregon A day to clean up things, prepare my one Rosy Finch from Mt. Thielsen, & drive
