California Condor
Eben McMullan
30 July 1964
Even though good numbers of Turkey vultures came and fed on the
two deer carcasses I put on the hill south of my grain Tank
within the last two weeks, no Condor have shown up. It is probably
worthy of note that during the hot, dry summer months the Carcass
of an average sized deer is only available for two or three days
at the most. Otherwise it dries up and putrifies.
It now appears that Condors, if in need of food, Scout a
large portion, if not their total range constantly. Should
food be made available anywhere within the Condor range,
that is available as food to Condors, they will find it providing
they are in short supply. Even though only one Condor should
find a usable source of food, and providing this source
would supply more than the one Condor, others will come in
within a day or two, to feed. Thus even for ranging probably
check in at the Central roosting location, which is probably
within the Sesepe Wildlife Preserve, each day or so. If Condor
find a plentiful supply of food, even at the extremes of their
range, and are seen only in small numbers, it would seem
safe to postulate that other food is available in good
quantity else more Condors would soon come. Therefore it is my
thinking, that, in times of need, the total Condor range is hunted
constantly and that communication is made between Condors
when an ample supply of available food is found.
Deer undoubtedly furnish a relatively constant food supply
for Condors. Range Conditions over such a large area as the total
Condor range, offers varied weather conditions throughout the
seasons - A drought with corresponding die-off in deer could-
