The three condor on ground have not yet gone in to actually feed on the deer carcass. They stay back and watch the Ravens gorging themselves. Something is strange with this scene. Either these condor have fed previously or else they are aware of my watching them all the time from this vantage point at least one-half mile away. I will now leave this location that is about 1/4 mile Northeast of our sulphur camp and move to a vantage point among the Oak trees where I will be less conspicuous to see if this has any effect on the behaviour of the condor in feeding. Thus I at 12:46 p.m. left my former location on the steep ridge, on the north side of sulphur canyon. Before I had reached the bottom of the canyon to where I would be out of sight of the deer carcass, five condor had lit on the ground and three of them were feeding on the deer carcass at 12:50 p.m. crossing the canyon and working my way towards camp through the Oak timber, that grows on the north slopes of Sulphur Creek below the level of our camp; I came out in an area where I could again see the soda-sulphur ridge and the area where the bait was put out. At least six condor were on ground fighting over and dragging, the deer remains about. I remained hidden watching the condor for several minutes but wanting to see if my presence, in clear view of where they were feeding would frighten the condor, I walked out into an opening that is about —
