While getting my binoculars out and moving outside the pickup to where I could take a rest on the engine hood, I lost sight of both Condor. After watching the hillside for ten minutes, where I had last seen them, I saw one adult Condor walk from behind a tree and stand on the ridge that runs up a bit north of where the P.G.&E. Gas line goes. This bird stood for several minutes before it flew out to the north, skimming the Oak tops as it went. As it proceeded northward the young spot-in-wing bird came up from the ground through some oaks on the north facing ridge and followed the adult. Both continued northward, seeming to be troubled considerably in gaining elevation, and circled for several minutes over the mouth of the canyon south of Rambo's barn. After circling this canyon mouth for about two minutes with little success in gaining altitude, and being dive-bombed by a Red- tailed Hawk, both birds moved back southward over the route they had just come, and the adult, at least, that I happened to be watching, landed in the top of an Oak, uphill about one- hundred feet from where it had been on the ground some five minutes before, on this ridge north of P.G.&E. pipeline.
