California Condor Eben Mcmillan 26 may 1964 I drove to the home of Jim Rutledge at 601 Villa Street, in Porterville, Calif., at 6:30 p.m. Mr. Rutledge did not get in from his job of poisoning squirrels until a short time before I arrived at his home. It should be understood that when I mention the poisoning of squirrels literally, in all cases it should be realized that the species, California Ground Squirrel (Citellus Beecheyi) is being referred to. Mr. Rutledge had not seen Condor this year although he mentioned as having normally seen them during the squirrel poisoning campaigns of former years. He feels quite sure that condor and Buzzards feed on dead squirrels that were poisoned with compound 1080 mixed grain. Mr. Rutledge said that the strength of the compound 1080 poison that he is currently putting out is one ounce to one-hundred pounds of grain. This mixture, he feels, is strong enough whereby six grains of treated poison-potted, rolled, barley is sufficient to kill any normal adult California Ground Squirrel in a short time. Mr. Rutledge told me of counting the number of grains of poison grain in the pouches of one adult California ground squirrel that had died from the effects of 1080 poison as being one-hundred grains. He thinks that cannibalism in squirrels accounts for about 35 percent of the total of 98 percent death in squirrels in a concentrated campaign. He feels that this 35 percent die up to three weeks after the poisoned grain has been spread out from the effects of-
