California Condor
Eben McMillan
26 February 1964
Getting difficult to keep track of each condor, where it was
going and what it was doing. To add to this confusion more Raven
had come in swelling their numbers to about 18 or twenty birds.
Also one Turkey Vulture came up from the South, remained
along the south side of Soda-Sulphur Ridge soaring back
and forth for about five minutes before leaving the area and
not being seen again.
one condor circling showed a large gap in middle of left wing.
one Condor showed 5th primary missing from left wing.
At 12:15 P.M. Ten Condor were circling above the baits.
one Condor with about 6th primary missing from right wing.
one Condor with gaps ½ and ¾ way out missing from left wing
Condor were coming and going but a doubt that any left
that did not return. At 12:20 P.M. one Condor dropped down
and lit near deer carcass. It walked to carcass and commenced
feeding but soon walked about Ten feet away and stood. Another
Condor soon landed near this one, both stood and watched the
ravens feeding on the deer carcass. One of these
Condor walked over and fed on the deer carcass but seemed
very fearful and leery and when one of the raven would
flap its wings this Condor would jump back and look at,
or towards, the raven as if fearful that something was
wrong. From this I gathered that some of these Condor
had witnessed others of their kind caught in traps
or the like and those surviving developed a fear of anything
like this that was not completely natural.
Two Condor and eleven raven were at the deer carcass -
