California Condor Eben McMillan 26 may 1964 Secondary Poison achieved by the remaining living squirrels feeding on the poisoned bodies of others of their species. He also stated of having found the poisoned carcasses of many Kangaroo Rats that have died of the poison put out for squirrels during a squirrel Poisoning Campaign. Mr. Jim Rutledge has heard rumours of a non-secondary poison having been discovered that could be very lethal to squirrels but he admits not having had factual evidence of this poison nor has he heard of any research being conducted that would lead to the development of a poison that would be more selective than Compound 1080, and not be dangerous as a secondary poison. He thinks that no poison will ever be developed that will compare with Compound 1080 in effectiveness that is not of a Secondary Poisoning nature. Mr. Rutledge has never heard of anyone shooting at, or killing, a Condor, nor has he ever heard of a dead Condor. When I first discussed Condor problems with Jim Rutledge this evening he stated that Condor had not been seen in the foothills of Tulare County before 1953. This he had based on the fact that he had Poisoned squirrels in this area since 1944 and had heard no mention of Condor prior to 1953 nor had he seen them. As our Conversation progressed Rutledge retracted this statement and reconsidered the matter claiming that Condor must been in the foothill area of Tulare County prior to 1953.
