Text of Note

Vichos non-lethal collars containing 45 to 105 ml of 3% capsicum oleo resin were evaluated as deterrents to coyote attacks on sheep. Each of five coyotes tested made neck/throat attacks on one collared lamb; four punctured collars and one pulled the collar from a lamb without puncturing it. One coyote did not resume biting the lamb for 60 min; it was retested two and four days later. At two days, the coyote punctured a second collar and briefly halted its attack. At four days, the coyote attacked a third collared lamb but made no attempt to grasp the neck/throat area. In tests resulting in collar punctures (n=5), coyotes immediately stopped their attacks and showed obvious signs of oral irritation; however, attack behavior resumed shortly thereafter (mean= 17 .6 min). Coyotes resuming attacks directed them toward the sides and rears of lambs. The Vichos collar is unlikely to prove effective in controlling coyote predation on sheep.
