California Condor Eben McMillan 25 JUNE 1964 quite old. On one boulder that stands at the entrance to Nest No. 5 Cave a print of the pad and two of the foes of a Condor were left here on the top surface of this boulder by a Condor having stepped in fresh excrement just before hopping onto this boulder. This white stain was easily scraped away so could not have been many months old. A pair of Canyon Wren had built their nest in a crevice in the top of the Condor Cave of Nest No. 5 and today this nest contained several well developed young. From all the evidence we could gather, after having spent 30 minutes in Nest No. 5 Cave, we concluded that very probably, a Condor egg was abandoned at this nest this spring. Woodrats, that had carried ample supplies of acorns into the back recesses of this cave, would in time, have cleaned up all fragments of egg shell remaining on the surface of the nest sand. Woodrats would probably break any large egg left unguarded in this cave for any length of time. We left the Cave of Nest No. 5 about 11:00 A.M. The sun had not at this time reached the entrance to Nest No. 5 Cave although it would probably do so about 2:30 P.M. No wind blew at the entrance to the cave although a good breeze was blowing when we arrived in the saddle below Whiteacre Peak to the Northwest. I would think afternoon temperatures in mid-summer, in the area where Nest No. 5 is located could get oppressively warm. Probably in the nest cave it would not get so warm. I think the sun would shine in-
