p.245 -Continued- California Condor Eben Mcmillan 9 August 1963 be a population of 21/6 deer to every Township, or 9600 deer within a 40 mile square area that could be well within the range daily range of a feeding condor. population of 9600 deer would likely furnish, on an area more than one dead deer per day. Probably under conditions, a condor could locate a dead deer within two days, within a 40 mile square area. With other wild mammals furnishing a fairly stable supply of Carcass, it's doubtful that condor would be experiencing any food shortage, at any season, through the foothills of the West Sierra Nevada Mountains. John Rofer left to care for a sick Bull at 9:00 A.M. after advising me to watch the carcass of a Cow that had died and been 'dragged' to a Swale about 1/4 mile north of the house where Mrs., a sister in law of Mr. Rofer and who had been doctoring the Cow in question for two months before it finally died. This being the case, is doubtful that much meat would be left on the Carcass after it had been sick for so long. It's doubtful that buzzards or condors would find this carcass tempting. Mr. Rofer, before leaving, told me of the gentleness of 13 Condor that Dr. Elliot McClure had photographed. Thirteen of these Condor had alighted in an Oak Tree and remained in this tree while Dr. McClure took pictures of them. Mr. Rofer has driven to within 100 ft. of Condor on different occasions in his car. Rofer has not seen condor at close range for ten years. Only young condor seem to trust the close approach of humans now. I have not been able to get closer than 250 yards to a feeding Condor this year and on most occasions, Condor have flown when approached within one half mile by a car, or by a human, in open.
