Califorria Condor
Eben McMillan
21 August 1963
Condor
West face of Frazier mountain that overlooks the Lockwood
valley. Soon more Condor rose up from below the crown of
Frazier mountain. Five were counted, then a sixth bird
was noted coming from the west and [illegible] high. The
birds played about along the west, and southwest
of the mountain, riding the strong up-currents of air
were the result of a brisk west wind being deflected up
as it hit the west slope of the mountain. One of these
Circled up, gained an elevation somewhat higher than
that of Frazier mountain and then flew northward in a direct
line over Cuddy Valley continuing on northwest until
a great distance from me, when it turned more westward and
disappeared from sight.
Turning back to the other Condor that were still playing
about, having now moved more to the southwest crown of
Frazier mountain where it looks out over the Mutau Flats.
The five remaining Condor were now joined by five more
that seemed to come up the [illegible] valley at an elevation
about equal to that of the Frazier Mt. Lookout that is at
elevation of 9026 feet. The ten Condor now present continued
to lower out of sight below the crown of the mountain then
rise suddenly on the strong wind currents whereby one
bird might rise a thousand feet in making one circle. We noted a tendency among these condor to
keep in pairs. At least many of them. At one time
five of these Condor drifted southeastward up Piru
creek and about the northeast slope of Alamo mountain
only to return to the southwest face of Frazier mountain
again and join the other five Condor that circled in this
area while they were away.
One Condor finally left the flock of ten and moved
around the east side of Frazier mountain at an
elevation perhaps higher than the mountain top, chose
