California Condor Eben McMillan 9 July 1963 Drove to Gene Rambo Ranch by 8:30 A.M., Gene and his boy were unloading hay. He said he had seen no Condor for several months. I told him that I had seen two Condor go into the Canyon back of his home last evening. He seemed quite surprised for he said they were Roping steers at 7:00 P.M. yesterday evening and should have observed any Condor that were within sight of his Roping arena. The Two Condor were over the Roping arena at 6:50 last evening. I drove to a hilltop 1/2 mile Southwest of the Gene Rambo home and with the aid of BTL Spotting Scope soon picked out two adult Condor roosting in a Digger Pine Tree on the ridge above Rambo's Tin Hay barn in Maule Canyon and about one mile West of where I sat. The time was 9:05 when the birds were first seen. Both were preening and stretching. The morning was warm. At 9:40 A.M. the top bird sat down on the limb on which it Berched. As it sat down the tail was held high briefly, as if to maintain balance, then the tail and wings dropped as this bird continued sitting down, see diagram below- Sitting Posture Perch under breast bone Tail and wings drooping and fan back of Perching Limb of tree. Center of condors weight well forward. At 9:45 A.M. the sitting Condor stood up and stretched, then reclined in normal roosting posture - See diagram below- Normal Roosting posture- Perhaps even more perpendicular with the body than this -
