California Condor Eben McMillan February 26 1964 Canyon at the time these planes roared up its drainage leaving long tails of black smoke, they could have been hit, for at the speed these aircraft were traveling Condor would be hit before they even knew what was coming. These two planes continued on up Hopper Canyon passing directly over the nesting area near Hole-in-the-wall. The roar of their engines would seem to me to be a disturbing influence to Nesting Condor if not downright frightening them. And, of course, there is a real danger of hitting one of these Condors or an eagle as these planes fly up this canyon so low. I am sure there is supposed to be restrictions on the flight pattern over this Sage wildlife area. Jack Gaines once told us that planes must maintain a 500 foot ceiling over the Sage wildlife area. Perhaps these planes were 500 feet above the canyon bottom but less than 500 feet from the cides of the canyon on each side of them. It would appear that if these planes continue to pass through this area in this way that it is just a matter of time until one of them hits a large bird of some sort. It Condor would probably bring them down. At 10:30 one of the two Condor that had circled above the bait for the last fifteen minutes came north and circled near the north face of Sulphur Canyon near where I was now crouched in the sage bushes. I am sure it saw me but paid no heed and after gaining some elevation moved out of sight to the North at 10:31.
