Gymnogyps californianus

tulare Co., Calif.
Tule Indian Reservation,
one adult at this tree. Another man said the birds absent-

the first. There was a pine tree (18") about 25' from the
nest hole & directly in front of it. A large stub branch
extended from a cut 6' hole from just below the nest. I supposed
the young one would eventually perch there. One man said
the adults sometimes perched in another redwood about
200' downhill from first. Forest less of yellow pine, bigtree,
Douglas fir, & sugar pine. The bigtrees were supposedly
not to be logged but some were sawed & fence posts had
been split from them. Rouch said that logging commenced
about May 1 and continued until stopped by rain+
snow (Oct. to Dec.). Elevation at tree about 6500
ft. Lola Location 1 mile NW Parker Peak. Rouch's address:
Box A, Springville, Calif. The existence of this young bird
in nest shows that a nest, once started, can stand very
strong periodic disturbances, even blasting, without causing
adults to desert. It may be that disturbance was slight
until after egg hatched. Trees around nest tree hide it
from observers except from a few points so that bird at
nest may see few men. It will be important to note
whether this site will be used again after sustaining
so much disturbance. The existence of this nest shows
means that there may be nesting in the Tehachapis or
Kern Canyon areas and that all condors seen in this
part of their range are breeding birds with nests. It is
