California Condor
Eben Millman
21 July 1964
Mr. Harris also told us of gliding in one of these cyclonic winds
with what he took to be a condor, some months ago. He thought
the bird he was sharing this updraft with had a dark head that
was feathered. Harris said he was 7 or 8 feet from the bird when it
dove below him and was lost from his sight. Harris claims to have
observed swallows at 12000 ft. hawking insects in the air. He claimed
to have seen large hawk-like birds as high as [illegible] 16,000 feet.
elevation.
Mr. Harris stated that he has observed large birds flying at
60 plus miles per hour ground air speed. He claims it is not an
unusual incident for a glider pilot to reach air speeds of 125
miles per hour or more in level flight. Mr. Harris feels that condor,
with natural [illegible] characteristics that enable them to reach
much higher perfection in soaring flight than is the case with a
fixed wing glider, should have no problem in soaring 100 miles
per hour or even faster when at high altitudes and with
favorable air currents.
