Taste aversions have been developed in wolves, coyotes, and other canids to protect livestock and vulnerable wildlife. In 1974, it was reported that coyotes (Canis latrans) learned to avoid hamburger after eating hamburger treated with lithium chloride and could transfer such a drug-induced aversion of LiCl-tainted sheep or rabbit (Sylvilagus sp.)
The development of taste aversions in wolves, coyotes, and other canids is thought to protect livestock and vulnerable wildlife. In 1974, it was discovered that coyotes learned to avoid hamburger after consuming hamburger treated with lithium chloride, and could then transfer this aversion to sheep or rabbit (Sylvilagus sp.) contaminated with the same drug.
