News clipping from S.L.O. County - North County Journal had July 1 - Covering this Event is filed. California Condor Ebert J. McMillan 2 July 1964 I drove to the area on the Carissa Ranch that had been used as an experimental ground, only the last two days, in spreading Poisoned grain from an aeroplane to kill squirrels. This area is on the San Juan river drainage about fifteen miles up-river, or S.E., from the La Panza Bridge on highway. I was present when this experiment went on. When the process of dropping the poison was worked out. That was on June 30, 1964. The actual poison was applied yesterday. I remained in this area for three hours, from 10:00 A.M. to 1:00 P.M. One Turkey Vulture wheeled by at 12:45 P.M. At no time did I see Raven or Magpie about the area although both can be found here. No Eagles were about. I doubt that many Poisoned Carrasses were about. It seemed to me this aerial scattering of poison will be very ineffective in controlling ground squirrels and could bring about the loss of livestock. On one area where a shower of this poison had been dropped the ground was bare and the dropped grain could be seen. This poison was flake enough so that where it fell in grass on which Cattle were grazing, there could be losses. Where falling in Grass, Ground squirrels and Kangaroo Rats would probably find few grains of the poisoned material. I would doubt this method of Poisoning Ground squirrels will ever prove successful. Compound 1080 was used to treat the grain used here.
