California Condor Eben McMillan 30 July 1964 easily develop in one area and not necessarily affect other areas of the range. 1964, with a total drought in eastern San Luis Obispo County with heavy mortality in Cattle Sheep and deer occurred while ample rains and very satisfactory range conditions exist along the eastern foothills of the San Joaquin Valley. Heavy die-off in heifers and calves in the foothills of the southeastern San Joaquin Valley due to what is termed foothill abortion took a tremendous toll of these types of Cattle while little or no trouble with heifers calving was evidenced in other sections of the Condor Range. Deer season commences west of Highway 99 in early August running into mid-September that no doubt furnishes a plethora, even if dangerous, [illegible] of food for Condor. No sooner does the hold-over of food from this early deer season run out than the later, or East of Highway 99 deer season take place. This deer hunting in itself should furnish all Condor with ample food for three months (Aug-sept-Oct) of the year. We have now fairly established that except for a lull in late May, June and early July, Cows are Calving throughout the Condor range throughout the Year. The above are but a few of the factors that can be used to substantiate our thinking that food for Condor is of no consequence as a survival factor.
