Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller Apr 2007

Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller

Wildlife Damage Management Conference Proceedings

Several factors may be responsible for increasing predator abundance in suburbia. These include an enhanced forage base associated with residential sprawl, and protection of predator species that were once persecuted and suppressed by hunters, trappers, and landowners. In the Northeast, anecdotal reports of coyotes (Canis latrans) killing pets in backyards are on the rise. The bulk of coyote complaints, concerns, and questions received from the public by state wildlife agencies are from areas with high human populations. Scant research exists on coyote behavioral ecology in human-altered landscapes. Biologists and managers need to understand changes in the social structure …


A Review Of Successful Urban Coyote Management Programs Implemented To Prevent Or Reduce Attacks On Humans And Pets In Southern California, Rex O. Baker Apr 2007

A Review Of Successful Urban Coyote Management Programs Implemented To Prevent Or Reduce Attacks On Humans And Pets In Southern California, Rex O. Baker

Wildlife Damage Management Conference Proceedings

Since the fatal coyote (Canis latrans) attack on a 3-year-old girl in Glendale, California in 1981, government agencies have emphasized developing coyote management programs to increase public safety. This presentation will focus on the success of numerous programs including: small neighborhoods, industrial sites, parks, large city and county-wide projects. Local environmental conditions attracting coyotes, specific problems caused by the coyotes, public reaction, and the role of public relations including public education emphasizing environmental management, will be discussed. Coyote population monitoring regarding behavior patterns, aversive conditioning, and coyote population reduction methods will be reviewed. Trapping remains the most effective …


Assessing The Impact Of Urban Coyote On People And Pets In Austin, Travis County, Texas, Randy O. Farrar Apr 2007

Assessing The Impact Of Urban Coyote On People And Pets In Austin, Travis County, Texas, Randy O. Farrar

Wildlife Damage Management Conference Proceedings

The City of Austin acquires citizen reports of coyote (Canis latrans) observations or complaints through a toll-free non-emergency 311 telephone call system. The observed coyote behavior or activity reported by constituents is categorized into one of eight behavioral categories that correlate with observed changes in coyote behavior indicating an increasing risk to human safety. The categorical data is used to formulate indices of coyote behavior for accessing and monitoring the relative risk of urban coyotes to human safety over time. Behavioral indices with respect to established management zones are used to prioritize and target areas for preventing or …


Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt Apr 2007

Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt

Wildlife Damage Management Conference Proceedings

Coyotes (Canis latrans) have become common in many metropolitan areas across the United States. Recent research has focused on the urban ecology of coyotes to better our understanding of how they exist in urbanized landscapes. I summarize findings from a variety of ecological studies of coyotes in or near metropolitan areas, and focus on three areas of coyote ecology: survival rates, home range/activity, and food habits. Most studies have reported relatively high survival rates (annual S = 0.62 - 0.74), with vehicle collisions often a common cause of mortality. Size of coyote home ranges (mean home range sizes …


Response To Coyote Predation On Pets, Dorinda Pulliam Apr 2007

Response To Coyote Predation On Pets, Dorinda Pulliam

Wildlife Damage Management Conference Proceedings

An urban coyote (Canis latrans) management program was initiated in Austin, Texas in January 2005 to address citizen’s concerns that coyotes were becoming aggressive towards humans. Although preserving public safety is the fundamental foundation for the program, concomitant program objectives have evolved to include addressing citizens’ high levels of concern regarding predation and attacks on house pets. From the citizen’s perspective, it is unacceptable to ignore this issue, and demands for responsiveness have been heavy. The City of Austin’s program has responded to this public concern in two ways. First, coyote conflicts involving pets are included in the …


My Experience: Setting Up An Urban Campaign Or Trapping Project For Urban Coyote Management, Dairen Simpson Apr 2007

My Experience: Setting Up An Urban Campaign Or Trapping Project For Urban Coyote Management, Dairen Simpson

Wildlife Damage Management Conference Proceedings

I discuss my personal experience in urban coyote (Canis latrans) management, including the following elements: 1) necessary liaisons and alliances (who are they?); 2) choosing methodology (pluses and minuses of each option); 3) necessity for target selectivity and minimal time at site (knowing when to quit, and ways to know); 4) public contact and on-site education for all concerned; 5) inter-agency contact and communication (remaining allies through the thick of it); 6) media communication; 7) following up actively after incidents or control work; and 8) examples of train wrecks and successes.

Coyotebytes.Org: A New Educational Web Site, Robert M. Timm Apr 2007

Coyotebytes.Org: A New Educational Web Site, Robert M. Timm

Wildlife Damage Management Conference Proceedings

A web site, www.CoyoteBytes.org, has been developed as a tool to provide sciencebased management recommendations to homeowners and municipal officials on methods to reduce conflicts with coyotes (Canis latrans) in urban and suburban areas. Such conflicts include aggression toward or attacks on children and adults; attacks on pet dogs and cats; attacks on hobby animals, such as poultry, sheep, and goats; and damage to drip irrigation systems, garden crops, and to other resources. In addition to providing information, the website allows individuals to upload photos or video clips of urban and suburban coyotes, and to submit firsthand reports …


Impacts Of Urban Coyotes On People And Pets In New York State, Louis T. Berchielli Apr 2007

Impacts Of Urban Coyotes On People And Pets In New York State, Louis T. Berchielli

Wildlife Damage Management Conference Proceedings

Coyotes (Canis latrans) are currently common in most of New York State with an apparent increase of coyotes in urban areas. Coyotes can potentially cause a variety of effects and impacts. Urban coyotes can impact the general public by causing safety concerns for children and pets and by causing feelings of grief for attacked and missing pets. Politicians and government agencies can be impacted by calls from constituents to “do something”. Licensed Nuisance Wildlife Control Operators can be positively impacted by significant business opportunities. Pets are impacted by coyote diseases and by being chased and consumed by coyotes. …

The author provides advice on dealing with municipalities, the media, the public, and with clientele. Also discussed are appropriate tools and materials that can be effective in such settings, and effective strategies for dealing with suburban coyote problems.


Urban Coyotes: Some Summary Thoughts, Jeffrey S. Green Apr 2007

Urban Coyotes: Some Summary Thoughts, Jeffrey S. Green

Wildlife Damage Management Conference Proceedings

The Animal and Plant Health Inspection Service, Wildlife Services program provides services on request to help alleviate damage by wildlife to agriculture, natural resources and human health and safety. Such services may also involve dealing with coyotes (Canis latrans) in urban settings. Resolving problems with urban coyotes requires a mix of suitable methods but perhaps more importantly, an understanding of complex social and cultural issues surrounding people and wildlife.


Suitable And Effective Coyote Control Tools For The Urban/Suburban Setting, Alan A. Huot, David L. Bergman Apr 2007

Suitable And Effective Coyote Control Tools For The Urban/Suburban Setting, Alan A. Huot, David L. Bergman

Wildlife Damage Management Conference Proceedings

Increases in the incidence of human conflict with coyotes in urban/suburban environments fuel a need for suitable coyote tools and methods to reduce these conflicts. Traditional tools, such as foothold traps and snares, face continued problems of acceptability in urban/suburban situations because of public anxiety about the risks to non-targets as well as other animal welfare concerns. We review the major categories of methods and tools used to prevent or reduce urban coyote-human conflicts, including exclusion (fencing), environmental and habitat modification, capture devices (traps, snares, and related devices), and shooting. We briefly discuss future technologies current under development: fertility control, …


Operational Challenges Of Solving Urban Coyote Problems In Southern California, Dennis L. Orthmeyer, Terrance A. Cox, John W. Turman, Joe R. Bennett Apr 2007

Operational Challenges Of Solving Urban Coyote Problems In Southern California, Dennis L. Orthmeyer, Terrance A. Cox, John W. Turman, Joe R. Bennett

Wildlife Damage Management Conference Proceedings

We present challenges, methodologies, and solutions related to mitigating urban coyote (Canis latrans) problems in southern California. The physical environment, the diverse urban structure (green belts and parks) with its abundant food resources which support high coyote densities, combined with the human component (behavior, urbanization, politics) create operational challenges. The increasing disconnect between humans and wildlife, coyote emigration/immigration into the increasing rural/urban interface, and coyote life cycles that occur exclusively in urban environments, all contribute to the increase in coyote-human conflicts. California’s southern counties’ human population has expanded 13% over the period from 1990-2000 and is projected to …


Bad Dogs: Why Do Coyotes And Other Canids Become Unruly?, Robert H. Schmidt, Robert M. Timm Apr 2007

Bad Dogs: Why Do Coyotes And Other Canids Become Unruly?, Robert H. Schmidt, Robert M. Timm

Wildlife Damage Management Conference Proceedings

We summarize the behavior of several species of canids (coyotes, dingoes, and gray wolves) in relation to their habituation to humans and to human food sources. Striking parallels exist between coyotes and other wild canids in terms of the inclination of individual animals to act aggressively toward humans and even attack, once they have come to associate humans with food. We describe the stages of coyotes’ behavioral adaptation to suburban ecosystems, listing 7 steps toward increasing habituation, which can be used as action thresholds for invoking active coyote management or removal efforts. We consider the hypothesis that coyotes may regard …


Complexities Of Urban Coyote Management: Reaching The Unreachable, Teaching The Unteachable, And Touching The Untouchable, Robert H. Schmidt Apr 2007

Complexities Of Urban Coyote Management: Reaching The Unreachable, Teaching The Unteachable, And Touching The Untouchable, Robert H. Schmidt

Wildlife Damage Management Conference Proceedings

Urban coyote (Canis latrans) management is often complicated, but the technical portion of any management program is only one part of the equation. The use of lethal (traps, snares, shooting, toxicants) and non-lethal (exclusion, guard animals, husbandry practices, harassment) coyote management strategies can be successful, less than successful, or not successful depending on the appropriate match of technical skill and technology available in a particular situation. However, technical sophistication is only a portion of the management dilemma. Issues of policy, law, politics, and economics, as well as human values, attitudes, and ethics play an obvious and profound role …


A Broad Perspective On Current And Future Research On Urban Coyotes, John A. Shivik, Kathleen A. Fagerstone Apr 2007

A Broad Perspective On Current And Future Research On Urban Coyotes, John A. Shivik, Kathleen A. Fagerstone

Wildlife Damage Management Conference Proceedings

A change in wildlife management appears to be occurring. Previous efforts needed to be focused on producing more game species or endangered animals; now, however, tools and training must resolve issues of overabundance and conflict with predators, especially species such as coyotes (Canis latrans) in urban areas. Urban conflicts with coyotes may be growing because of urban development of land and human intrusion, but alteration of habitats that attract coyotes is also a likely factor. Research that will describe basic coyote biology in urban areas will be needed, but managers will also need applied research and development of …


A History Of Urban Coyote Problems, Robert M. Timm, Rex O. Baker Apr 2007

A History Of Urban Coyote Problems, Robert M. Timm, Rex O. Baker

Wildlife Damage Management Conference Proceedings

We summarize previously published information on coyote attacks on humans in North America. This problem has developed primarily in urban and suburban areas of southern California since the early 1970s, and the frequency of attacks and other human safety incidents is increasing. Similar attacks are now known from at least 18 states in addition to California and from 4 Canadian provinces, with the majority of attacks occurring since the early 1990s. We review early explorers’ and settlers’ accounts of coyotes in the Los Angeles area, as well as development of coyote control programs during the 20th century. We also describe …


Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson Oct 2000

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 Oct 2000

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 Oct 2000

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 …
