California Condor Eben McMillan 9 July 1963
Drove to Gene Rambo Ranch by 8:30 A.M., Gene
and his boy were unloading hay. He said he had seen no
Condor for several months. I told him that I had seen two
Condor go into the Canyon back of his home last evening.
He seemed quite surprised for he said they were Roping
steers at 7:00 P.M. yesterday evening and should have
observed any Condor that were within sight of
his Roping arena. The Two Condor were over the Roping
arena at 6:50 last evening.
I drove to a hilltop 1/2 mile Southwest of the Gene
Rambo home and with the aid of BTL Spotting Scope
soon picked out two adult Condor roosting in a Digger
Pine Tree on the ridge above Rambo's Tin Hay barn in
Maule Canyon and about one mile West of where I sat.
The time was 9:05 when the birds were first seen. Both were
preening and stretching. The morning was warm. At 9:40
A.M. the top bird sat down on the limb on which it
Berched. As it sat down the tail was held high briefly, as
if to maintain balance, then the tail and wings dropped as
this bird continued sitting down, see diagram below-

At 9:45 A.M. the sitting Condor stood up and stretched, then
reclined in normal roosting posture - See diagram below-

Perhaps even more perpendicular with
the body than this -
