Book Seasonal Movement Patterns of Coyotes in the Bear River Mountains of Idaho and Utah

Download or read book Seasonal Movement Patterns of Coyotes in the Bear River Mountains of Idaho and Utah written by Glen F. Gantz and published by . This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coyotes (Canis latrans) prey upon domestic sheep. The Animal Damage Control (ADC) program currently relies heavily on aerial gunning in winter to control coyote depredations on mountain grazing allotments. Some people claim that winter aerial gunning is not effective because coyotes migrate to lower elevations during winter, following herds of big game animals, and may not be on the allotments where summer depredations occur. I studied the seasonal movement patterns of coyotes in the Bear River Range of Utah and Idaho to determine if coyotes in montane habitats move on a seasonal basis. Radio-collared coyotes were located from fixed-wing aircraft from 13 November 1987 to 15 September 1989. I used 3 parameters to assess interseasonal movement patterns: overlap in seasonal home ranges, distance between harmonic mean centers of activity, and seasonal differences in mean elevation. All mature coyotes showed overlapping seasonal home ranges, which suggests they did not move substantially between seasons. In contrast, none of the sub-adult coyotes had seasonal home ranges that overlapped. Distances between harmonic centers of seasonal activity were easily assigned to one of two groups (9́Þ5000 m and 9́Þ10,000 m). These corresponded precisely with coyotes that did and did not display overlap in seasonal home ranges. Significant changes in the elevations of seasonal locations were not evident for any age or sex group. I conclude (1) that movement of sub-adult coyotes in the Bear River Range is part of dispersal behavior and is not motivated by seasonal change and (2) that these sub-adult coyotes generally cease wandering during their second years. My findings are similar to other studies where nomadic wandering was more common among sub-adult coyotes and was not correlated with season. I saw no movement of coyotes from the mountains to valley locations. Adult coyotes were in the same location in summer as in winter.

Book Impacts of Coyotes Canis Latrans on White tailed Deer Odocoileus Virginianus Behavior and Mortality in the Chicago Region

Download or read book Impacts of Coyotes Canis Latrans on White tailed Deer Odocoileus Virginianus Behavior and Mortality in the Chicago Region written by Gretchen C. Anchor and published by . This book was released on 2019 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) and coyotes (Canis latrans) have spread into metropolitan areas in recent decades. How these species interact with the landscape, other species, and each other is of interest to managers of these human-dominated areas. In the Chicago region, little is known about the relationship of white-tailed deer and coyotes. Our study aimed to elucidate the predator-prey relationship as well as how white-tailed deer respond behaviorally to coyotes as a result of this relationship. To answer questions on the predator-prey relationship between these two species, 81 white-tailed deer fawns were collared and monitored to determine causes of mortality. The analysis of 172 coyote scats also provided insight into this relationship by determining dominant food sources. Predation by coyotes was the primary cause of mortality (77.8%) of white-tailed deer fawns at our study site. Furthermore, white-tailed deer remains were found in most coyote scats (53.5%) but the presence of these remains were highest in scats collected in the summer (83.9% in 2017; 61.3% in 2018). The results of the fawn mortality analysis and scat analysis suggest that there are high incidents of coyote predation on white-tailed deer fawns but provide little evidence of predation on adults. With this specific predator-prey relationship, there is potential for behavioral asymmetries between age classes and sexes of white-tailed deer. To determine how this relationship influences white-tailed deer behavior, we chose to study antipredator behaviors because these behaviors are expressed in relation to predation risk. Following the “ecology of fear” framework, we expected to see increases in antipredator behavior by fawns and does with fawns in response to coyotes coyotes due to the possibility of habituation as a result of exposure to high coyote densities. We chose to investigate the antipredator behaviors of vigilance and avoidance in response to coyotes. Through the use of camera traps, we captured white-tailed deer foraging behavior in response to an indicator of coyote presence, specifically coyote urine. Through this test, we found that white-tailed deer of each age class and sex do not increase the amount of time spent vigilant while foraging when an indicator of coyote presence was present. To look for signs of avoidance of coyotes, white-tailed deer and coyotes were fitted with radio collars and monitored concurrently. Home range overlap was found for all deer-coyote dyads studied indicating that white-tailed deer are not selecting home ranges that allow the complete avoidance of coyotes. After analysis using the half-weight association index, however, results suggested avoidance behavior occurred for all deer-coyote dyads. These results show that the white-tailed deer monitored in our study avoid being within 200 m of coyotes. The results of both the vigilance survey and avoidance testing provide evidence of habituation, regardless of age class and sex, to an indicator of coyote presence and the lack of avoidance at the landscape level. These results, however, indicate that white-tailed deer at this site show finer-scale avoidance by avoiding coming into close proximity with coyotes. Our study provides valuable information on the coyote-deer predator-prey relationship and the behavioral responses of deer to this relationship in the Chicago region.

Book Home Range Size Vegetation Density and Season Influences Prey Use by Coyotes Canis Latrans

Download or read book Home Range Size Vegetation Density and Season Influences Prey Use by Coyotes Canis Latrans written by Jennifer N. Ward and published by . This book was released on 2018 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: To ensure reproductive success, Canis species establish contiguous mosaics of territories in suitable habitats to partition space and defend limiting resources. Consequently, Canis species can exert strong effects on prey populations locally because of their year-round maintenance of territories. We assessed prey use by coyotes (Canis latrans) by sampling scats from within known territories in southeastern Alabama and the Savannah River area of Georgia and South Carolina. We accounted for the size and habitat composition of coyote home ranges to investigate the influence of space use, vegetation density, and habitat type on coyote diets. Coyote use of prey was influenced by a combination of mean monthly temperature, home range size, vegetation density, and hardwood forests. For example, coyote use of adult white-tailed deer (Odocoileus virginianus) was associated with cooler months and smaller home ranges, whereas use of rabbits (Sylvilagus spp.) was associated with cooler months, larger home ranges, and less vegetation density. Coyotes in our study relied primarily on nutritionally superior mammalian prey and supplemented their diet with fruit when available, as their use of mammalian prey did not appreciably decrease with increasing use of fruit. We suggest that differential use of prey by coyotes is influenced by habitat heterogeneity within their home ranges, and prey-switching behaviors may stabilize local interactions between coyotes and their food resources to permit stable year-round territories. Given that habitat composition affects coyote prey use, future studies should also incorporate effects of habitat composition on coyote distribution and abundance to further identify coyote influences on prey communities.

Book Food Selection Home Range and Movements of Coyotes on and Off a Sanctuary in Klamath Basin

Download or read book Food Selection Home Range and Movements of Coyotes on and Off a Sanctuary in Klamath Basin written by Suzanne Shoemaker and published by . This book was released on 1985 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio-telemetry and scat analysis were used to investigate daily and seasonal movement patterns and food selection of a protected coyote population on Tulelake National Wildlife Refuge (TLNWR) and adjacent Lava Beds National Monument (LABE) in northeastern California. Study emphasis was on evaluation of movements on and off the sanctuary, and movements and food selection relative to manipulated and undisturbed sites. Nineteen coyotes were trapped and fitted with either radio-telemetry (12) or color-coded (7) collars between 1 November 1982 and 5 May 1983. Home ranges were estimated for eight sanctuary coyotes (two composites) by two methods: (1) 95% minimum convex polygon (MCP) and (2) 90% contour of the utilization distribution. Home ranges were small (95% MCP's : 0.5 - 6.2 km2) and elongate, including portions of both irrigated cropland (TLNWR SW Sump) and undisturbed rangeland (LABE) habitats. Coyotes used cropland habitat primarily for foraging purposes, and rangeland for resting and denning. Elongate shape reflected movements back and forth between habitats. Territoriality was demonstrated. Intensive monitoring of four coyotes from May through September 1983 indicated coyotes used larger areas at night (1700 to 0900) than in daytime (0900 to 1700) during pup-rearing (23 May to 8 August) and dispersal (15 August to 20 November) seasons. Home ranges and core areas were larger for both diel periods in dispersal season than in pup-rearing season. Variable patterns of coyote use of irrigated cropland habitat were attributed to individual energy demands, human activity, and vegetative cover. Only one individual (adult male) was known to make daily excursions off the protected area. Some seasonal migration off the sanctuary took place in late fall, winter, and early spring. Spring migrations may relate to human disturbance on agricultural lands. Food habits analysis showed coyote diet was more diverse in all seasons on the undisturbed rangeland (LABE) than on the irrigated cropland (SW Sump). Montane voles, Nuttall's cottontails, and mule deer were winter staples on LABE. Many other foods (sciurid and heterormyid rodents, insects, berries, birds) entered LABE coyote diet in late spring and summer. Montane voles were the dominant coyote food year round on SW Sump. Birds entered SW Sump coyote diet in substantial quantities only during pheasant and waterfowl hunting seasons in late fall and winter. A model for optimal use of a patchy habitat and its application to coyote foraging strategy and use of manipulated (simple, homogeneous) versus undisturbed (complex, heterogeneous) environments is discussed, as are some management implications.
