California Condor--Continued
3 april-19
became fluffy and took on the sheen - one usually
sees on condors in flight. This bird had two primaries
missing in the left wing and the last primary before
the secondaries start appeared to be only about 2/3
grown out.
This Condor preened, fluffed and stretched its [illegible]
until 11:25 A.m., when it faced the edge of the Ca
rock, on which it had been perched, opened its [illegible]
and flew out, and down, behind the rock. It stayed
behind this rock, evidently dropping lower and
crossing the Beartup Valley, for when a next picker
up in my glasses it was circling about one mile
to the Northwest. It soon gained altitude and when
last seen disappeared behind the big rocks
that are on top of the ridge above the old Queen
Bee Mine, heading West by Northwest.
This bird had bright white under its wings but the
white bar on the top of the wings was not definite
in fact when the wings were folded tight the white bar
couldn't be seen. The head was red but the
neck buff covered most of the neck. The head was
yellowish and appeared to be rather bare on the
neck. See diagram below -
