Coyotes: A Potential Role In Deer Herd Management?, Robert E. Zaiglin
Coyotes: A Potential Role In Deer Herd Management?, Robert E. Zaiglin
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
White-tailed deer (Odocoileus virginianus) herd control is one of the principal problems faced by private lands game managers. Private landowners unwilling to permit adequate numbers of sport hunters on their lands force deer managers to exercise other harvest strategies, one of which is natural population control by protecting the coyote (Canis latrans). I describe an ongoing case study in South Texas where predation by coyotes may be considered a positive tool in deer population management.
Alternative Methods Of Predator Control, Crystal A. Wilbanks
Alternative Methods Of Predator Control, Crystal A. Wilbanks
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Acceptable solutions to animal damage problems must consider the social and recreational values of wildlife, regulation of population levels, potential hazards of chemical use, human safety and disturbance to biotic communities. The objective should be to reduce harm and economic loss of livestock to an acceptable level. This paper, reviews alternative, i.e. nonlethal, predator management methods. Alternative methods include guard animals, fencing, repellents, frightening devices and perhaps someday, immuno-contraception. The intent of animal damage control should be an integrated pest management approach tailored to fit the individual landowner's needs.

Coyotes (Canis latrans) are abundant throughout North America, some of the highest densities occur in south Texas. Most studies indicate abundance of food as a contributing factor of coyote density. High coyote populations can lead to localized depredation problems and the current canine rabies epizootic is of concern to residents of south Texas.
Coyotes In Urban Areas: A Status Report, Jan E. Loven
Coyotes In Urban Areas: A Status Report, Jan E. Loven
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Coyotes (Canis latrans) occur within the city limits of most urban areas in Texas, and the Incidence of human X coyote interactions appears to be increasing in recent years. The major damage caused by coyotes in urban areas has been depredation on pets (primarily) and to other animals (e.g., ducks). Direct control of such problem coyotes is often hampered by city/state regulations and/or concern from local officials about negative publicity.
Effects Of Coyote Control On Their Prey: A Review, Scott E. Henke
Effects Of Coyote Control On Their Prey: A Review, Scott E. Henke
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Coyotes (Canis latrans) are often removed from an area because of their predatory nature, regardless of the effect such removal may have on the ecosystem. Research results concerning ecosystem changes due to coyote removal appear ambiguous; however, differing lengths of coyote control can produce different results. Short-term coyote removal efforts (≤ 6 months) typically have not resulted in increases in the prey base; however, long-term, intensive coyote removal reportedly has altered to alter species composition within the ecosystem.

When asked their views about coyotes and coyote damage, the words used by producers to describe their perspectives and comments are less than kind. It is difficult for a producer to find anything good to say about an animal that has cost him so much.
Techniques For Estimating Coyote Abundance, Scott E. Henke, Fred F. Knowlton
Techniques For Estimating Coyote Abundance, Scott E. Henke, Fred F. Knowlton
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Knowledge of coyote abundance is needed to make intelligent management decisions Several methods have been devised to enumerate coyote (Canis latrans) population size. We review several techniques and attempt to identify biases associated with each method. Once biases are understood, recommendations can be made to minimize their impact on data collection processes and yield better estimates of coyote population trends.

Prescribed Coyote Control To Develop An “Open Window Policy” For Enhancing Deer Survival, Tommy L. Hailey
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Management of white-tailed deer (Odocoileus virginianus) holds a high priority on many Texas ranches today The use of “prescribed aerial control” of coyotes to increase white-tailed deer productivity may provide wildlife managers with an economical management tool. I describe two case studies of ranches in the Lower Rolling Plains where prescribed coyote control has increased the deer herds.

Most information published by the Texas Agricultural Statistics Service (TASS) is based on data gathered through a system of Sample Surveys. TASS regularly surveys sampled farms and ranches and agricultural businesses m order to make statistical inference (estimates) for a total population. The alternative to using a sample survey would be to make a complete enumeration or count of the entire population. Both cost and timely results favor the survey approach. This discussion is an attempt to explain the concepts and sampling methods TASS employs in conducting basic surveys, for both inventory and death loss data for cattle, sheep and …
Lethal Options For Controlling Coyotes, John W. Dorsett
Lethal Options For Controlling Coyotes, John W. Dorsett
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Lethal control methods are required to stop coyote depredation or to reduce the coyote population in an area. Various lethal control options are available, including traps, snares, shooting, denning and toxicants. The effectiveness, selectivity, and specificity of each method should be considered before being utilized. Each method requires varying degrees of skill and experience to be made effective. Usually a combination of control methods is most effective in coyote control situations.
The Effects Of Control On Coyote Populations: Another Look, Guy E. Connolly
The Effects Of Control On Coyote Populations: Another Look, Guy E. Connolly
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Population dynamics models are useful for estimating coyote (Canis latrans) population responses to exploitation w well as to hypothetical birth intervention techniques At least 6 coyote simulation models have been developed over the past 25 years. This paper reviews the model developed by Connolly and Longhurst (1975), and identifies some potential improvements based upon new biological information and modem computing technology. The biological concepts embodied in the Connolly-Longhurst (C-L) model seem as valid In 1995 as they were in 1975. Newer studies have tended to reaffirm rather than revise earlier concepts of coyote population mechanics. One significant shortcoming …

The Coyote's Role In A Rabies Epizootic, Keith A. Clark, Pamela J. Wilson
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
In 1994, the canine rabies epizootic in South Texas was declared a state health emergency; a statewide rabies quarantine was enacted in 1995. Prior to 1988, rabid coyotes (Canis latrans) were reported only infrequently in Texas. In 1988, Stan and Hidalgo Counties, located In extreme South Texas, experienced an epizootic of canine rabies resulting in 11 laboratory-confirmed cases of canine rabies in domestic dogs and 6 cases in coyotes. By 1991, the epizootic had expanded approximately 100 miles north of the US-Mexico border and included 10 counties. During the next 3 % years, 10 additional counties became involved …
Predation Impacts And Management Strategies For Reducing Coyote Damage To Cattle, Rickey L. Gilliland
Predation Impacts And Management Strategies For Reducing Coyote Damage To Cattle, Rickey L. Gilliland
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Loss of cattle to predators influences productivity of many livestock operations. Statistics indicate that coyote (Canis latrans) predation is a principle threat. Impacts to livestock resources by coyotes are appraised. Implementation of control strategies which capitalize on coyote dispersion and social interactions are discussed. Predator management to reduce livestock losses and promote a younger age structure in coyotes is suggested as a long term solution.

Interpreting Physical Evidence Of Coyote Predation, James E. Bowns
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
There are situations where it is necessary to determine the cause of death of livestock, game animals, or other wildlife. Criteria used for recognizing predator kills are well known and scientifically documented. These criteria include the attack, killing and feeding behavior of predators as well as the characteristics of their tracks, droppings, and canine teeth size and spacing. Diagnostic criteria for recognizing coyote (Canis latrans), domestic dog, fox (Urocyon cinereoargenteus, Vulpes vulpes), cougar (Felis concolor) , bobcat (Lynx rufus), bear (Ursus spp ), and eagle (mostly Aquila chrysaetos) predation are …
Coyote Interactions With Other Carnivores, Terry L. Blakenship
Coyote Interactions With Other Carnivores, Terry L. Blakenship
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Coyotes (Canis latrans) occur sympatrically with several predators throughout their range. Habitat and food resources are similar, although the coyote typically utilizes a wider range of food items. Larger predators generally select larger prey, allowing predators of different sizes to coexist. Coyotes exhibit aggressive actions towards smaller predators, but in most cases they avoid contact with other predator species. Studies indicate that coyotes can exclude 01- displace foxes (Vulpes vulpes, Urocyon spp.), and an inverse relationship exists between abundance of coyotes and foxes. There is evidence suggesting that extensive reduction of coyote populations allows other predator populations …

Selected Parameters Of The Reproductive Physiology And Endocrinology Of Coyotes, Max S. Amoss Jr., Connie M. Hodges
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
The development of the reproductive system and the dynamics of reproductive hormones were studied in captive male and female coyotes (Canis latrans). Captive male coyotes exhibited incomplete sexual maturation at the first reproductive season (< 12 months of age). Peak serum testosterone levels in 1 -year old males were 50% (300±200 vs. 810±300 pg testosterone/ml) and total sperm production was only 10% (57.4±6.6 vs. 558.8±26 x 106 total sperm) of that observed in males older than 1 year. Yearling males were never observed copulating with a female. The sexual maturation of captive female coyotes was less equivocal than their male counterpart's. The pregnancy rate of yearling females was 40% compared to 63% m older females. Average peak serum LH values at the ovulatory surge were 33 ng/ml in yearling …
Behavior Of Coyotes In Texas, William F. Andelt
Behavior Of Coyotes In Texas, William F. Andelt
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Coyotes (Canis latrans) live in social groups with relatively small territories or as single, non-territorial transients with large home ranges in southern Texas. Coyotes communicate and establish territories through auditory, olfactory, and visual means They consume mammals, fruits, and insects with their diets reflecting difference sin abundance and vulnerability of prey, effects of plant phenology and weather conditions. Coyotes have adapted to human exploration by avoiding humans and their control techniques. Because coyotes habituate to nonlethal control techniques (e.g., frightening devices), I suggest apply frightening devices only when coyotes are a problem. Lethal techniques likely will be most …

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
The challenge and thrill of recreational hunting for coyotes (Canis latrans) has increased greatly over the last 20 years. The popularity of calling coyotes especially is increasing east of the Mississippi River as coyote populations continue to increase their range and abundance in that area.
Coyote Population Processes Revisited, Frederick F. Knowlton, Eric M. Gese
Coyote Population Processes Revisited, Frederick F. Knowlton, Eric M. Gese
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
It appears that coyote (Canis latrans) abundance is determined primarily by availability of food (prey) as mediated through social dominance hierarchies and a territorial land tenure system. This is reflected in rates of reproduction, dispersal, and mortality, with survival of juveniles a major factor. Suggestions for a new generation of simulation models to explore coyote population functions are included.
Coyotes And Upland Gamebirds, Fred S. Guthrey
Coyotes And Upland Gamebirds, Fred S. Guthrey
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
That coyotes (Canis latrans) destroy nests and individuals of bobwhites (Colinus virginianus) and wild turkeys (Meleagris gallopavo) is well documented. In many situations, however, the removal of coyotes would have little observable effect on gamebird recruitment and population dynamics. This counterintuitive result occurs because (1) renesting reduces the hen failure rate and (2) loss sources other than coyotes become stronger when coyotes are removed from a predator-prey system.
Coyotes As Part Of Texas' Fur Trade, Jerry L. Cooke
Coyotes As Part Of Texas' Fur Trade, Jerry L. Cooke
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
One factor that potentially affects coyote (Canis latrans) abundance is recreational and commercial trapping for harvest of coyote fur. Herein I report how the economic impact of coyote pelts has changed from 1979-94 for landowners and trappers from the Texas. Pelt values accounted for over 50% of the variability observed during this 15-year period. The future of this economic incentive for managing coyotes is questionable because of the impending ban by the European Union of furs from North America.
Management Of Coyotes For Pronghorn?, S. Kemble Canon
Management Of Coyotes For Pronghorn?, S. Kemble Canon
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Coyotes (Canis latrans) and pronghorn (Antilocapra americana) have co-existed for thousands of years, but in today's production-oriented society the Pronghorn may need some help periodically. Although pronghorn numbers have rebounded dramatically since the early 20th century, continued management of this species is necessary and may include "management" of its primarily predator, the coyote. Pronghorn defense mechanisms offer protection from predators, but the coyote's hunting strategies overcome these mechanisms The Trans-Pecos region of Texas holds the greatest numbers of pronghorn In the state. Ranchers in the Trans-Pecos can use predators, such as rainfall; strategies, such as proper …
Audubon's Perspective On Coyotes, Dede Armentrout
Audubon's Perspective On Coyotes, Dede Armentrout
Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
Audubon has a membership which probably spans all views of coyotes (Canis latrans) Audubon's staff views coyotes as biologically appropriate predators in most of the Southwest. We believe that they can be an asset to a well-managed ranch, but that they can also cause localized depredation which must be answered.
Our members value predators, including coyotes, for then- natural role in ecological systems, including their influence on prey species. Many of our members travel broadly and spend money to view wildlife, and consider it a treat to see and hear coyotes.
Predator Politics In Texas, Bill Sims

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)
The coyote (Canis latrans) is certainly one of the most destructive predators affecting the livestock industry, particularly sheep and goats. In fact, title of this session is very appropriate, because when you talk about “politics”, coyotes seem to have more politicians working for them than any other animal.

My career as an extension wildlife specialist and a university administrator has allowed me to monitor both the public and private sectors' perspectives on coyotes (Canis latrans) and their associated management policies. Selected experiences described herein illustrate the problems (current and future) that characterize emotionally-charged conflicts like those typified by coyote control efforts.

Predators and predator management in general are always controversial topics. As with most controversies, both ends of an emotional continuum vie for the attention of the nonvocal, uncommitted majority. To provide unbiased information on the controversy surrounding coyotes (Canis latrans) in Texas, the Texas Agricultural Extension Service produced a 23-minute video in 1991. The video addresses both "sides" of the coyote "coin" while providing factual biological information on the topic. The video has been quite popular, and has received both state and national awards.
