California Condor
Eben McMillan
22 August 1963
It remained cool and windy throughout the night. Fog
showed along the range to the south of the Antelope Valley. The
heavy prevailing west winds here must be somewhat of a barrier
to large soaring birds for I have not seen buzzards or Eagles
out in the center of the Antelope valley.
Shepherds in the Tehachapi Valley reported not having seen
any condor in that area. I saw 25 plus buzzards and many
raven in a stubble field east of the Tehachapi city dump
where the carcass of a sheep was that had died five days before.
Most of the meat was gone from the bones of this carcass
that showed having been dragged about by many
scavengers.
At lunchtime I watched Turkey buzzards passing
but to the west from the eastern section of Tehachapi
Valley. A strong west wind was blowing. It was moderately
cool. The buzzards seemed capable of moving along into
this stiff west wind at a pace of approximately ten to
15 miles per hour. They held an altitude of about seven or
eight hundred feet above the valley floor but remained in
the westerly wind current en route for one could tell from
the way they were buffeted about when trying to move
crosswise to the wind current that it was quite strong. Their
progress seemed quite steady in the face of this wind. They
held a straight course up the center of the valley. No
buzzards were seen moving westward along the sides
of the valley with the exception of three buzzards that
were progressing westward, very close to the ground, along
the foothills on the south side of Tehachapi Valley. These three
birds were making slow progress westward. Their flight was
very erratic being within three or four feet of the ground one moment,
then fifty or sixty feet high the next. After gaining a mile or so
of westward progress these three buzzards floated back eastward
on the wind and after arriving in the lower part of
