California Condor Eben McMillan 15 may 1964 Top of hill about one quarter mile south by southeast of foot of Kerr grade.

As I watched this Condor heading eastward, high, from direction of Cholame Rancho Headquarters, I momentarily dropped my glasses in order to make my sitting position more comfortable and when glassing the skies again could not relocate this high flying bird but instead picked up what I am sure was another Condor that had just cleared the hills across the valley from me and near where the P.G. and E. Pipe line comes from the east foothills into the valley. This Condor could not be identified as to age due to the distance it was from me. This second Condor raised up very fast, circling, and when at a rather high elevation, this bird dipped its wings and went into a flat glide, seeming to gain elevation as it passed on and out of sight, above Sam Wallace Rocks, with no apparent intent of changing its course. The day was very clear with little haze and high thin cirrus clouds made conditions near perfect for seeing a great distance. My binoculars are 9x35 B & L. I feel certain I can follow a Condor in flight, under ideal conditions such as was the case today, for twelve miles. This Condor passed from my field of vision when it was still well above-
