Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson
Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson
Wildlife Damage Management Conference Proceedings
Capture rates and injury rates of coyotes (Canis latrans), bobcats {Lynx rufus), and raccoons (Procyon lotor) captured in standard No. 3 Soft Catch® traps were compared to those captured in the same trap type modified with the Taos Lightening Spring™ (TLS) double torsion spring. All traps were equipped with Paws-I-Trip™ pan tension devices and were successful in excluding most small nontarget species. We captured 15 coyotes and 17 bobcats from October 1995 to March 1997. In addition, 23 raccoons, a large nontarget species, were captured. Capture rates for coyotes were higher (P < 0.10) in TLS modified traps (92%) than standard traps (27%), whereas capture rates were similar (P > 0.10) for raccoons (85% and 67%, respectively) and …
Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin
Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin
Wildlife Damage Management Conference Proceedings
The range expansion and reintroduction of mammalian predators (e.g., wolves, coyotes and bears) coupled with growing disfavor for traditional tools of wildlife management creates an immediate need for alternative, non-lethal, but effective techniques for managing predation on livestock. Scientists at the National Wildlife Research Center are using advanced technology and animal behavior concepts (e.g., aversive and disruptive stimuli) to develop new tools for the prevention of damage by large mammalian predators, and this paper is a review of our pilot studies investigating these techniques. Recently tested tools include behavior contingent disruptive stimulus devices for wolves and coyotes. Experiments indicate the …
Effectiveness Of Anise As A Coyote Lure, Coren P. Jagnow, Russ Mason
Effectiveness Of Anise As A Coyote Lure, Coren P. Jagnow, Russ Mason
Wildlife Damage Management Conference Proceedings
Odors are frequently used to attract coyotes (Canis latrans) to control devices. Coyote olfactory perception is vital to effectively manage depredation of livestock by coyotes because of the importance of volatile cues to this species. Lures are usually chosen to reflect the biological needs of coyotes as well as relying on food-seeking behaviors to elicit attraction. Anise (Illicum verum) was chosen as the stimulus because of its attractiveness to dogs and its common use as an ingredient in animal foods. Plants comprise a large part of coyotes' diets during warm weather; therefore, a plant odor was chosen to find an …
