California Condor Eben McMillan 2 may 1964
Take movies of the Condor. As they approached the
area of the Sheep Carcass the Condor, that were now
sitting about on the ground, resting, Took off on the wing
and sailed out to the Southeast along the ridge that
divides the Bitterwater drainage from the San Juan river
drainage.
Later this evening Jan reported last seeing six Condor,
that had circled as a group of eight over an area about one-
and one-half miles southeast of Kerr Grade, fly out of sight
to the Southeast while the two of the Eight returned. We last
saw the six Condor go out of sight at 11:20 A.M. According
to my State of California, Department of Natural Resources, Division
of Forestry map of San Luis Obispo County, the air line distance
between the foot of Kerr Grade and my house is eleven and
one-half miles. Now suppose the six Condor, last seen by Jan,
were one and one-half miles southeast of the foot of Kerr Grade
when he last saw them. This would make the distance they
would need to cover, to reach my home, as ten miles. There
seems good reason to assume that the one Condor Gladys
McMillan saw over our home at 11:30 A.M. was one of
the group of six Condor that Jan last saw at 11:20 A.M.
This then seems to be substantial evidence that the
six Condor covered the ten miles in ten minutes,
or an average speed of one mile per minute. This
Corresponds to the Speed we established a Condor
traveled over an estimated distance over the top of
Frazier Mountain last year.
