CALIFORNIA CONDOR Eben McMillan 6 July 1963
I was on the Cholame flats at 8:30 A.m.. Turkey Buzzards
were just coming off the tops of dead cottonwood trees that grow
in the Cholame Creekbed one half mile southeast of the Cholame Ranch
Headquarters. These Buzzards were all heading out southeastward.
The air was calm and flying conditions seemed good for the
Buzzards were sailing about with effortless ease, doing very
little circling to get elevation and moving very easily. I took
up a watch on the rock outcropping to the east of Hancock Ranch
Road, remaining there until 10:45 A.m.. Not seeing any Buzzards
in this area, although lots of Raven were along the stream that comes
from the Canyon to the north, I returned to the area near the
Ranch Headquarters, stopping at the roadside, in the creek bottom,
one mile southeast of Headquarters buildings. I now saw several
Buzzards circling the valley and some were alighting and feeding on
the Boll Calf carcass on which a Condor had fed last Tuesday.
Condor At 11:40 A.m. two Condor were seen circling above the old maulve
house on the Gene Rambo Ranch. When first seen both condor were
circling and gaining altitude. After gaining moderate altitude one
condor glided out northeastward slowly to be followed closely by
the other Condor. Both birds drifted across the valley and circled again
about one mile north of Cholame Ranch Headquarters. When circling here
I could make out that one Condor was quite ragged in plumage while
the other was in very good plumage. Both were in adult plumage.
Breaking from this circling both condor headed east and were
lost from sight after having glided for five minutes due east.
When last seen both condor were still together, about 30 seconds
after having lost sight of the Condors far out above the Wallace
Place I picked up an object that could have been one of these
Condor, for it was in the same general area the Condor were last seen.
It was traveling northwestward fast.
Do Condor use an angled route to go from Cholame flats to
Castle Mountain? To Wallace Place then double back to Castle Mountain?
Any Condor nesting in Castle Mountain at the present time?
