Gymnogyps californianus
May 3, 1946 Nr. Famoso, Calif.
mistakable (I saw the pictures). Maximum number
of condors in photos was 2 or 3. Joe said that buzz-
ards & condors eat the membrane but not the digestive
tract of the poisoned squirrels; he believes they would
be poisoned only if they ate this. Coyotes & bob
cats are killed easily by secondary poisoning, Joe
said, but apparently not birds. The buzzards
give way to the condors & stand around in a circle
while condors are feeding, Joe said. Occasionally a
condor snaps at a buzzard with bill. Condors
can be approached quite close in a car - to
within about 40' at times, says Joe. Sometimes
they will fly a short ways carrying the squirrel
in their bill rather than relinquish it, said Joe -
buzzards do this too. The buzzards often stand
around & turn their backs with wings out but
Joe has not seen condors do this. The "triangle" form-
ed by the Bakersfield-Porterville, McFarland-Woody, & Famoso
Woody highways has been the most frequented condor
area, below says Joe. Once, Joe says, he flushed a
condor & a golden eagle from a carcass at Poso
Flat. Once, with Everett Horn, he saw condors feeding
on a calf on Tojai Ranch before squirrel poisoning
season. He said he had seen condors feed on sheep
& cattle but mostly on squirrels - he thinks they
especially like them. The condors follow 1 or 2 days
