Abstract
Experiments were conducted with microencapsulated LiCl to find a concentration that would produce optimum sheep-bait aversion and to test the transfer of the bait aversion to sheep killing aversion in naive (no sheep-killing experience) and sheep-killing coyotes (C. latrans). LiCl at 1.08 g/500 g of sheep flesh, fed to coyotes at a rate of 500 g of treated flesh/10 kg of coyote body wt, produced the strongest bait aversion of the 4 concentrations tested. After showing strong aversion to baits fed at the above concentration, most coyotes (both naive and experienced) killed and fed on lambs, showing no transfer from bait aversion to predation aversion.
