Effect of preventive coyote hunting on sheep losses to coyote predation
Article Abstract:
Coyote depredation is an important problem for livestock producers in the western US, particularly in the sheep industry. Aerial hunting is a common tool used by wildlife managers to reduce predation. A new study assesses the effect of aerial hunting of coyotes on sheep losses to coyote predation in Utah and Idaho. The study shows that aerial hunting reduces lamb losses to coyote predation on summer pastures and also reduces the need for subsequent predation management in summer. Winter aerial hunting of coyotes also has some benefit.

Effect of coyote removal on sheep depredation in northern California
Article Abstract:
The perennial cull of coyotes in the western US is aimed at controlling their predation on sheep and other livestock, but variations in results have made details of the strategy's effectiveness unclear. A new study evaluates 13 years of data from the Hopland Research and Extension Center, where the previous studies were undertaken, to discover the most effective coyote control pattern. Results suggest a need for more selective targeting, with timing occurring prior to yearly peaks in losses.

A comparison of bobcat and coyote predation on lambs in north-coastal California
Article Abstract:
Domestic sheep and lambs in the western US are killed mainly by the coyote, although bobcats, which are major killers of wild neonate ungulates, are also known predators of the species. An assessment of the role of bobcat predation in domestic sheep fatalities occurring in the Hopland Research and Extension Center in northern Californian reveals that the sheep eaten by bobcats were scavenged. It is concluded that bobcats are not predators of domestic sheep.
