california condor Eben McMillan 24 June 1964 youngsters have become tired of them and left them to the parents, or adults, to play with. These Trailbikes were towards Fillmore from Oak Flat Ranger Camp. From Oak Flat Ranger Camp on towards Cow Springs we saw less sign of road use and abuse the farther we went. Arriving at Cow Springs Campground at dusk we soon had our evening meal and were prepared for the night. Poor-will commenced calling a few moments before dark. As happened when we were camping here before one Poor-will called within 100 feet of our camp. The jungle sound that ends the call notes could be heard very plainly. Also when this bird was not calling a series of low notes much like that of a mourning dove coo note sounded at spaced intervals for a period of 4 or five seconds. These short notes were very low and at time intervals of about two per second. I am not sure this was from the Poor-will, but if not I have no idea what it could have been from. Many large airplanes came over Cow Springs, and to the west, in late evening. At times one would be only a few minutes behind the preceding one. All were going to or from Los Angeles, probably most were passenger craft shuttling between Los Angeles and San Francisco.
