California Condor

28 June 1963
rapid this bird could beat the huge wings without
Creating any evident energy or thrust upwards. After the
Condor had beat its wings it remained stationary for several
minutes while the Buzzards that had dashed away a safe
distance, while the wing beating [illegible], how returned to the carcass
to feed. The Condor now disregarded the Buzzards feeding and
gave signs of being regal. After a three minute wait,
after the wing beating, the Condor spread its wings a bit,
hopped down the hill two or three times and took to the
air easily, drifting directly down the canyon and
out across the river valley to a point well on the
east side of the river valley before it commenced
to circle and gain altitude. As it circled and rose
upward I took several pictures to show the glint
of shine that reflects from the upper wing and
body feathers of adult Condor when they bank
into a turn when circling for elevation. After gaining
some altitude this Condor then drifted over towards
me giving good opportunity to see that this was yet
another bird that I had, as yet, not seen. Only two
outside Primaries of the left wing were full length,
giving a queer appearance to this wing tip. All other
wing feathers seemed to be in good shape and the white
under the wings of this bird was very bright white.
This Condor circled above me for several minutes,
gaining moderate elevation after which it went
into the flex-glide and moved along towards the
southeast. It lost altitude fast and when last
seen was below the top of the hills to the South
of Carnaza Canyon and moving along southward to the
east of the San Juan River Valley. When last seen this bird was
heading into a canyon area. The time was 1:15 P.M.
I drove to area on San Juan river below La Piazza bridge -
