California Condor
Eben McMillan
9. September 1963
earlier and had flown around the ridge to the south - while the
Condor that flew around the ridge and lit in the pine to the Northward
probably gained less than 50 feet in elevation in the exchange
of perches from the Oak to the pine - this last bird that flew out to
the South gained three or four hundred feet in elevation in its
exchange of Perches; and this must have been accomplished
with little or no circling for both Jan and I saw no more
of this bird after it disappeared from sight behind the hill To
the South and would have been forced to return into our
field of vision had it done any circling.
At 9:00 A.M. Buzzards commenced to leave their Perches and fly
out westward and circle over the flats west of the Farnsworth ranch
buildings.
Seven Condor were perched in trees in the general area at
9:00 A.M., at least two of which were young birds, one a
ring-neck and the other a blackheaded bird.
ONE of the Seven Condor above mentioned was perched in bent pine.
At 9:20 A.M. Another Condor came in high, then let down by dipping
the point of one wing and sideslipped in and lit on bent pine
above an other bird that was perched. As this Condor flapped
to light on tree the roosting Condor left, circled once then
realighted on branch in center of tree.
At 9:30 A.M. a Condor that had been perched in a dead pine
on the horizon, to the Southeast, stood up from a sitting position
it had held for the last half hour, on a small branch that looked
to be no bigger than a one inch pipe - See diagram below
for posture of this Condor while sitting.
