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.
