California condor Eben Mcmillan 26 June 1965 I went to the Carrissa plains, via Pinole Ranch where I stopped to check with a Shepherd at the Pinole Spring who said he had seen no large birds come to the carcass of a sheep that died near his house trailer. This shepherd has been in the U.S. for one year, having come here at the age of 18 years. In his native country, Spain, he had never worked with sheep but being interested in mechanics and had learned the Truck Repair business. His father has been in the United States for eight years, coming here as a shepherd and now working as an agricultural worker in the San Joaquin Valley. The shepherd whose flock grazes in Old Canyon, which is about five miles due west of the Carrissa Plains School, said he saw many birds come and feed on the sheep carcass that I had opened with my knife some four or five days ago, but that he saw no large birds with white under their wings. He also said two more sheep had died in the Second Canyon west of his camp in the last few days. I hiked to this area but found no dead sheep, probably not going far enough. I noted vines of Lupine (Albifrons) that had been pruned by sheep that were eating them. No green vegetation except large vines of Haplopappus and lupine are available to these sheep. They do not seem to eat the Haplopappus under any condition. Even though large lupine is seldom eaten by livestock, this flock of sheep are eating this lupine now. I feel the lupine is causing the recent deaths among these sheep. I investigated the carcass of the sheep that had died near the shepherd's Trailerhouse and the one that I had opened with my knife some several days ago. I did not see anything that would lead me to feel Condor had fed on this carcass although it had been well eaten on. Driving to San Juan River below La Punza Ranch Bridge, on Highway 178, I found the body of a dead sheep in the water of the river about one mile north of this bridge
