California Condor Eben McMillan 26 February 1964 Getting difficult to keep track of each condor, where it was going and what it was doing. To add to this confusion more Raven had come in swelling their numbers to about 18 or twenty birds. Also one Turkey Vulture came up from the South, remained along the south side of Soda-Sulphur Ridge soaring back and forth for about five minutes before leaving the area and not being seen again. one condor circling showed a large gap in middle of left wing. one Condor showed 5th primary missing from left wing. At 12:15 P.M. Ten Condor were circling above the baits. one Condor with about 6th primary missing from right wing. one Condor with gaps ½ and ¾ way out missing from left wing Condor were coming and going but a doubt that any left that did not return. At 12:20 P.M. one Condor dropped down and lit near deer carcass. It walked to carcass and commenced feeding but soon walked about Ten feet away and stood. Another Condor soon landed near this one, both stood and watched the ravens feeding on the deer carcass. One of these Condor walked over and fed on the deer carcass but seemed very fearful and leery and when one of the raven would flap its wings this Condor would jump back and look at, or towards, the raven as if fearful that something was wrong. From this I gathered that some of these Condor had witnessed others of their kind caught in traps or the like and those surviving developed a fear of anything like this that was not completely natural. Two Condor and eleven raven were at the deer carcass -
