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-
