White-tailed deer damage urban and suburban plantings as well as crops and stored feed. A high public demand exists for non-lethal control methods. Several frightening devices are available for deer and all can be categorized as auditory, visual, tactile, and biological. Several problems exist with frightening devices, including: effectiveness, acclimation, cost, and acceptance. We tested the efficacy of a frightening device that played pre-recorded distress calls of adult female white-tailed deer when activated by an infrared motion sensor. Potential benefits of the device are that deer are less likely to acclimate to animalactivated and infrequently projected calls and that distress …

Social structure and behavioral interactions between individuals shape basic biological processes, such as breeding; foraging and predator avoidance; movement and dispersal; and disease transmission. We used a targeted trapping strategy to capture kin groups of white-tailed deer (Odocoileus virginianus) during 2007 and 2008 in Sandhill Wildlife Research Area, Wisconsin, USA, in order to observe social behaviors. Because inferring family relationships from observation of behavior is subjective, we usedmeasures of genetic relatedness and parentage assignment tests to determine that our capture strategy was efficient for capturing related pairs (78% of groups contained 1 dyad of related animals). The results of …

Efficacy Of Proximity Loggers For Detection Of Contacts Between Maternal Pairs Of White-Tailed Deer, Ryan Walrath, Timonthy R. Vandeelen, Kurt C. Vercauteren

Contact frequency and duration estimates between individuals are important to understanding the behavioral ecology of wildlife species and the epidemiology of infectious diseases. A new technology uses proximity data loggers to record time and duration of contacts. We conducted an experiment at Sandhill Wildlife Management Area, located near Babcock, Wisconsin (USA) to compare probabilities of detecting intraspecific contacts among white-tailed deer (Odocoileus virginianus) maternal pairs (dams/fawns) based on detections from proximity loggers deployed on collars versus those obtained from direct observation. We defined 5 discrete probabilities of detection of a contact in terms of P (probability of detection …
