Gymnogyps californianus February 7, 1946 Nr. Whiteacre Pk., Clif. I do not believe the cave was used last year. At 11:50 I entered the cave - an adult condor soared 100±' overhead a few min- utes later (first seen flying today), then was heard to land nearby. Did & I collected bones - including epiphyses of bone, one rodent humerus (?), a piece of ungulate scapula, & rib fragments, & a weathered carnivore-like tooth. The usual lay: number of scans was present - hollow with end chewed off. A few bones were found at rear most part of the cave - perhaps rodents carried them there. The place where egg was found was dry & had a slight hollow with a deeper hollow in the center - no caver tracks or scratch marks were present, however, & this hollow was sticks littered like the rest of the floor. Left the cave at 12:15 - saw two adults perched in a Ps. step the cliff to S. of the cave, 150±' above us & 100±yds. uphill. Probably a pair which will nest this year, perhaps at this cave. New is evidence of the pair being together before keeping company at the nest site before the egg is laid. I hope to get a good idea of incubation time this year - perhaps will find a February egg at this spot. The trail had been repaired & brushed out as far as White- sore Pkls but not beyond - yet was possible
