california condor Eben McMullan 5 January 1963 above this area before drifting slowly northward, seven of them heading up along the east slope of Hopper Mountain and one passing slowly out to the northeast. At 12:25 as we were preparing to leave the Percy Ranch another condor was seen to the southwest that was flying northwest. We then drove down below Angels Pass and stopped in Little Hopper Canyon for lunch. At 12:45 P.M. while eating our lunch a black-blind phase of Condor was seen flying eastward about 1/2 mile south of where we were. With this bird we were sure of at least ten condor having been seen, that were all different birds, today. We returned the key to the Elder Percy in Fillmore and drove to Castaic Junction where we visited the dead-pit of Newhall Land and Cattle Company Cattle feed lot. We could find no evidence of any large birds having fed on any of the three fresh carcasses that were in the ditch, or pit. We returned home via Lebec - Maniopa and Tatt, following highway 33 to Blackwells corner. Stance up Bitterwater Valley to my home. No fog was in the San Joaquin valley but a deep smog deposit that we dropped into about 1/2 mile north of Old Fort Tejon on highway 99 and were in it, until we got to Choice Valley. Reviewing events of the last two days there is no doubt but that Condor concentrate in the Sespe Wildlife area in the winter months. Also, food appears to be no problem during the winter months - dead sheep were plentiful in Cuyama - four dead cattle on Percy Ranch none of which had been touched by condor would seem to substantiate this, as well as 140 Condor feeding at Newhall Land and Cattle Company Dead-pit. Also, Condor do seem to exert more effort in flying in winter months.
