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
