Modified Neck Snare

Connected to the swivel was the locking snare, which was comprised of a Cam-LocTM. Every 12-24 hours they were checked to reduce capture time, further reducing stress and injury. The coyote was then left in an isolated location and kept warm by blankets until the effects of the Telazol wore off. From these results researchers concluded that the modifications; enlargement of the snare diameter, removal of sharp edges, a firm anchor wire and the addition of the diazepam tab; were effective in capture efficiency, lowering occurrence of lacerations and decreasing death rates. Researchers took care in assembling the snares so that any traces of human scent were masked. Consumed at the time of capture, this sedative was important to live-captures by decreasing aggression thus lowering incident of injury (lacerations or bruising) and death due to stress or fatal injuries.

At the close of the study, 19 injuries and only one death occurred out of the 51 coyotes (cause of death unknown). Once captured, the coyote was restrained and the immobilizing anesthetic, Telazol, was administered to keep them stationary. The diazepam tab, also attached to the swivel, consisted of 40mg of crushed diazepam between two strips of cotton. The animal was kept warm during the cleaning and stitching of injuries, recording of weight, fitting of eartags and radiocollars, blood collection and injection of antibiotics and an antiparasitic agent. 51 coyotes were captured between 15 November-1 April over a period of 9,379 trap nights and 7,421 trap days.
