Deer refuge undertakes lethal coyote control September 24, 2020 Washington, Wahkiakum County Eagle

... "We did conduct coyote control at the Julia Butler Hansen Refuge for the Columbian White-Tailed Deer this year after a year of low fawn survival," Myers said in a written statement. "An intensive study conducted on the refuge concluded that fawn survival was one of the biggest factors affecting the deer population, and the main reason for low fawn survival was coyote predation...

DNR stresses urgency in addressing Chronic Wasting Disease in Minnesota June 5, 2021 Country Messenger

... The Minnesota Board of Animal Health (BAH) announced that 12 additional white-tailed deer tested positive for chronic wasting disease (CWD) as part of its ongoing investigation of a farm in Beltrami County. The DNR believes the situation at the Beltrami County deer farm significantly changes the risk assessment and concern about CWD in Minnesota...,


Assessment of the Effect of Urbanization on Diversity, Population Dynamics and Wildlife Interactions Using Citizen-science Camera Trapping and Ancillary Data. AW Parsons - 2020

... Using an integrated population model, I found that suburban white-tailed deer (Odocoileus virginianus) survival and recruitment were negatively related to coyote density at low levels of development but positively related at high levels of development, consistent with deer exploiting suburban and urban areas for concentrated resources and/or as refuges from coyote predation. Overall, I found that diversity, the frequency of interspecific interactions and prey population dynamics can all be higher in suburban areas...


Coyotes living near cities are bolder: implications for dog evolution and human-wildlife conflict J Brooks, R Kays, B Hare - Behaviour, 2020

... We analysed the reactions of 636 coyotes to novel human artefacts (camera traps) at 575 sites across the state of North Carolina. Likelihood of a coyote approaching the camera increased with human housing density suggesting that urban coyotes are experiencing selection for boldness and becoming more attracted to human artifacts... We also note physical traits in coyotes that could be the result of domestication-related selection pressures, or dog hybridization...


Survival of Neonate Mule Deer Fawns in Southern Utah: Effects of Coyote Removal and Synchrony of Parturition JT Hall - 2018 [PDF]

... Our results indicated that coyote control can decrease mortality and increase survival of neonate mule deer in some situations. Removal of coyotes was most effective when removal efforts occurred for multiple consecutive years, and when control efforts occurred in or near fawning habitat...


Impacts of Coyotes (Canis latrans) on White-tailed Deer (Odocoileus virginianus) Behavior and Mortality in the Chicago Region [PDF] G Anchor - 2019

... 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 adult ...


The recent spread of coyotes across North America did not doom deer populations March 20, 2019 North Carolina, Phys.org

Predation was the main source of mortality for adult females in our study, with coyotes (Canis latrans) being the sole predator capable of depredation in our study area... almost 90% of mortalities occurring during the Post-hunt time period happened during late winter before spring green up...


White‐tailed deer population dynamics and adult female survival in the presence of a novel predator MC Chitwood, MA Lashley, JC Kilgo, CE Moorman… - The Journal of Wildlife …, 2015 North Carolina

... Recent localized declines in white-tailed deer (Odocoileus virginianus) populations in the southeastern United States have been linked to increasing predation pressure from coyotes (Canis latrans), a novel predator to the region. Studies have documented coyotes as the leading cause of mortality for neonates, and 1 study documented coyotes as a mortality factor for adult females... Our data indicate that for low-density deer populations with heavy predation pressure on neonates, protecting adult females from harvest may not completely offset population declines. Coyote removal might be a necessary strategy because it could possibly increase very low fawn survival, which appears to be the most important vital rate influencing λ in our study. However, managers may have to start with reductions in adult female harvest ...


Scale-Dependent Effects of Coyote-Predation Risk on Patterns of White-Tailed Deer Browsing along Linear Forest Edges JLB Pierce, SA Dalinsky, AA Chenaille, LM Lolya… - Northeastern Naturalist, New York, 2015

... Predation can influence patterns of browse through decreasing White-tailed Deer abundance and influencing patterns of habitat selection... We did not observe a change in White-tailed Deer browsing at the landscape scale in response to variation in the risk of Coyote predation, or a mitigating role of escape cover. However, we did detect a tendency for White-tailed Deer to shift browsing from the forest edge to interior along transects with more Coyotes. Our study indicates that Coyotes in the focal area were likely influencing patterns of browsing primarily through behaviorally mediated indirect effects...
