California Condor EbamcMillan 9 July 1969 In this corner area where the flueguard made the rightangle turn and another large pile of granite boulders, some more than 8 ft. high, were about 100 feet uphill and out from the angle of the Corner. I photographed these dead rats along with the contents of their pouches. I also hiked across road, and valley bottom where I climbed a hill on opposite side of the valley and photographed area where I found the 28 dead rats. Seven more death rats were observed while passing across Canyon to photograph. Much sign of rats was evident where the above 28 rat carcasses were found. Throughout this grassland area below the Oak belt, where the band of granite boulders occur all along the foothills of the Southern Sierra Nevada range on the west slopes, great concentrations of rats (Kangaroo) occur on the south slopes and ridges where the grass grows scanty growth. There remains little doubt in my mind but that Condor could pick up enough dead Kangaroo rats whereby they would take in more than 100 grains of oats poisoned with 1080. Were this the case I am sure the Condor would not be long for this world. I collected all contents of dead Rat Pouches today and have them segregated as to area and type. I visited with Ambrosia Billard who ranches in the foothills about 8 miles west of Woody, Kern Co. He told me of not seeing Condor this year. Three years ago he said he saw a flock of Condor Numbering 20 or 30 Condor that were feeding on the carcass of a still-born calf, in the Oak belt near Woody. He said he has seen Condor feeding on Cows and Sheep; and that he has seen them feeding on road kill Jackrabbits along the bands,
