California Condor Eben McMillan 18 February 1964 Ian came at 3:50 A.m. and we left for Fillmore immediately, arriving there at 7:45 A.m. Ian left me at the Night-Camp of the Percy's in the mouth of Hopper Canyon while he drove on towards the Little Sespe, and Cow Springs, where he was to watch for Condor and time his observations, so that we could establish whether the Condor that were being seen in the Agua Blanca and Whiteacre peak area were the same birds that we see in the Hopper Mountain and Hopper Canyon areas. I loaded my pack into Eugene Percy's jeep and rode with him to his Hopper Mountain Ranch. I had brought with me a sack full of rabbits and a white housecat that had been either run over on the roads, or shot.

The cat and the remaining rabbits, I kept in the sack leaving them with my pack at the Bear Tree Cotrol above the Percy home. The last of these carcasses were put out on Soda-Sulphur ridge at 9:30 A.m. At 9:40 A.m. two Ravens and one immature Golden Eagle were seen circling above the area where the upper carcasses had been left on Soda-Sulphur ridge. At 9:45 An adult Golden Eagle moved northward along the upper reaches of Soda Canyon hunting close to the ground as it went. As this eagle came around the south end of Hopper Mountain to where it could see the upper rabbit carcasses, it immediately dropped down to where they were. From where I stood, near the Bear Tree —
