California condor
Eben McMillan
9 may 1964
To Cholame flats at 2:00 p.m. Several Buzzards came and
went to cow carcass that lay near old spring on Maule flat. They also
worked on the calf carcass that lay 100 feet east of this
cow carcass as well as another carcass that lay one-half
mile east and nearer the road. There was not much wind. It
was even a bit warm at times.
No other large birds were seen today.
plenty of food was becoming available for Condor. Three
more calves dead. There is something funny about these Calves
that are dying from malnutrition. The Condor and Buzzards do
not seem to open the carcasses up other than at the Naval
and the anus. Could it be that due to the emaciated condition
of these carcasses perhaps the skin becomes tough, or could it
be that the meat is not acceptable to the Condor not the Buzzards.
It can't be due to age for two carcasses I have watched
that were not opened up were of calves that died at birth.
The Cow and Calf that Condor, Turkey vultures, and
Ravens have been feeding on regularly on the Maule
Flat, by the old dry spring box, on Cholame Ranch, died
by causes other than malnutrition. Scavengers
worked on these carcasses quite thoroughly. I am
beginning to think that Cattle that have starved
to death are not good food items for Condor.
