Do Trap-Neuter-Return (Tnr) Practices Contribute To Human–Coyote Conflicts In Southern California?, Danielle M. Bucklin, Jennifer M. Shedden, Niamh M. Quinn, Robert Cummings, Paul Stapp
Human–Wildlife Interactions
One possible contributor to the unusually high number of conflicts between coyotes (Canis latrans) and people in urban southern California, USA, may be the abundance of free-roaming domestic cats (Felis catus; cats) subsidized by feeding and augmented by trap-neuter-return (TNR) programs. To determine if coyotes regularly prey on and consume cats, we combined visual and molecular-genetic approaches to identify prey items in stomachs of 311 coyotes from Los Angeles County and Orange County, provided to the South Coast Research and Extension Center, in Irvine, California, between June 2015 and December 2018. We detected cat remains in …

The monetary value of livestock losses attributed to coyote (Canis latrans) predation in North America has increased during the past 20 years. In Texas, USA alone in 2011, these loses were estimated at $6.9 million. To mitigate coyote-related livestock losses, several lethal and nonlethal control methods have been developed. However, there remains a need for better information to guide management decisions regarding cost-effective predator control strategies for livestock production systems. We acquired data, which was used in the model, from published literature from 1960 to present day, subject matter experts, and anecdotal information on coyote ecology. We developed …
The Marin County Livestock Protection Program: 15 Years In Review, Stephanie Larson, Devan A. Mcgranahan, Robert M. Timm
The Marin County Livestock Protection Program: 15 Years In Review, Stephanie Larson, Devan A. Mcgranahan, Robert M. Timm
Human–Wildlife Interactions
Predation by wild carnivores challenges livestock producers worldwide. To reduce or offset losses due to predation, a variety of predator control methods and compensation schemes have been developed. In 2001, Marin County, California, USA replaced its U.S. Department of Agriculture Wildlife Services (WS) cooperative predator damage management program with a county-run program that emphasized nonlethal methods for preventing and controlling coyote (Canis latrans) predation on domestic sheep (Ovis aries). This new Livestock Protection Program (LPP) cost-shared with livestock producers’ efforts to improve fencing, obtain and maintain guard animals, and other such nonlethal methods, and initially it …
Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein
Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein
Human–Wildlife Interactions
While the relationship between coyotes (Canis latrans) and house cats (Felis catus) may be characterized as one between predators and their prey, coyote interactions with domestic dogs (C. lupus familiaris) appear to be more varied and may include behaviors associated with canid sociality. While encounters between coyotes and dogs are difficult to observe, we capitalized on publically available video recordings of coyote-dog encounters to observe canid behaviors and examined 35 video clips downloaded from YouTube during fall 2014. We identified coyote-dog interactions that were playful, agonistic, or predatory; those that we could not clearly …
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Human–Wildlife Interactions
The number of attacks on humans by large carnivores in North America is increasing. A better understanding the factors triggering such attacks is critical to mitigating the risk of future encounters in landscape where humans and large carnivore co-exist. Since 1955, of the 632 attacks on humans by large carnivores, 106 (17%) involved predation. We draw on concepts and empirical evidence from the Predator-Prey Interaction Theory to provide insights into how to reduce predatory attacks and, thus, improve human-large carnivore co-existence. Because large carnivore-caused mortality risks for humans are comparable to those shown by other mammal species in response to …
Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck
Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck
Human–Wildlife Interactions
Abstract The concept of hazing (aversive conditioning) is often promoted as a tool for reducing human-coyote (Canis latrans) conflicts in urban environments. Little scientific evidence exists on the effectiveness of hazing, particularly hazing applied by residents (i.e., community-level hazing). Wildlife professionals question if residents will properly and consistently apply hazing techniques and if hazing impacts coyote behavior over short- and long-term periods. We describe two separate efforts designed to encourage residents to haze coyotes in the Denver Metro Area; a citizen-science program and an open space hazing trial. Both efforts were intended to be management techniques that either …
Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell
Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell
Human–Wildlife Interactions
Human-coyote conflict in urban environments is a growing issue in cities throughout the United States with the primary problem being the development of problem individuals that are overly bold and aggressive with people and pets. Little research has focused on management options to deal with this conflict. We better define lethal and nonlethal management strategies associated with proactive and reactive management of coyotes with an emphasis on management of problem individuals. We then provide data from research in the Denver Metropolitan Area (DMA) that focused on reactive lethal removal of problem coyotes and reactive nonlethal hazing (i.e., community-level hazing, a …
Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm
Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm
Human–Wildlife Interactions
Beginning with the emerging pattern of urban and suburban coyotes (Canis latrans) attacking humans in southern California in the late 1970s, we analyzed information from reported attacks to better understand the factors contributing to changes in coyote behavior. We subsequently used updated data collected largely in urban and suburban environments in the United States and Canada during the past 30 years to develop strategies to reduce the risk of attacks. In the 1990s, increased incidents of coyote attacks were reported in states beyond California and in Canadian provinces. We documented 367 attacks on humans by coyotes from 1977 …
