California Condor Eben McNillan 8 July 1963
Neck cleaning
IN this Neck cleaning process Condor keep the legs
straight but bending the body forward and downward while
Tail Points upward. They turn the Neck and head about on
Ground. This was done several times by each of these Condor.
Between Neck cleaning efforts, the Condor that had flown
from the carcass would hurriedly trot on up the hill several
feet to be soon followed by the other Condor. They give the
Impression of being very agile on their legs for such large
birds. While the Neck-cleaning and walking or strutting while
Going on the breast of each bird showed reddish like
the feathers were parted in the front. This, due I think, to
the full crop.
One of the Condor appeared to be the leader while the
other, the one that had fed last, was the follower. Both
Condor gave the impression of being very devoted and
attached as well as considerate of one another. Much
more so than is the case with most birds.
At 6:47 p.m. One Condor opened its wings and easily
became air-borne, soon to be followed by the Other. Wing
Pumping of the Wings took place as they first flew low
the foothills heading Northwest. After flying on for about
1/4 mile both birds commenced circling but still doing
pumping or flapping of the wings and drifting on to the
Northwest. Arriving at a point approximately above the
old house and barn on the Gene Rambo Ranch, the Condors were
able to get some altitude, which they maintained, while they
drifted westward. At 6:55 p.m. Both Condor, still circling,
lost altitude and lowered into the Canyon about
1/2 mile west of the Gene Rambo Home building.
Four Buzzards were still feeding on the Calf
Carcass at 7:00 p.m. as I left the area.
