Stress And Predation Impacts On North American Quail Translocations, Curt A. Vandenberg, Sarah A. Currier, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Translocations have been used in attempts to bolster or restore native quail populations for >150 years, often with little success. However, with some northeastern United States quail populations undetectable or extirpated, and others across the United States on the extreme decline, translocation as a tool for quail population restoration is becoming increasingly popular. Two factors contributing to translocation failure are physiological stress and predation. Chronic stress associated with translocations can result in weight loss, reduced immune system function, suppressed reproduction, and an altered fight-or-flight response. These stress-induced responses increase vulnerability to predation, the primary cause of quail mortality. Here, we …
Diurnal Occurrence Of Great-Horned Owls On Northern Bobwhite Hunting Properties In Southwest Georgia, Justin A. Rectenwald, Philip M. Coppola, Theron M. Terhune Ii, D. Clay Sisson, James A. Martin
Diurnal Occurrence Of Great-Horned Owls On Northern Bobwhite Hunting Properties In Southwest Georgia, Justin A. Rectenwald, Philip M. Coppola, Theron M. Terhune Ii, D. Clay Sisson, James A. Martin
National Quail Symposium Proceedings
Understanding interactions between prey species and their predators is essential to discerning the ecology and management fundamentals of a species. Great-horned owls (Bubo virginianus) have long been considered an opportunistic predator of northern bobwhite (Colinus virginianus; hereafter, bobwhite) and recent studies have demonstrated that bobwhite survival is reduced at higher great-horned owl densities (Rectenwald et al. 2021). Managers on quail properties often mechanically remove live oak (Quercus virginiana) hammocks as part of larger predation management plans to reduce the amount of suitable predator habitat. While scattered live oaks are typically left for aesthetic purposes, …
Common Ravens Disrupt Greater Sage-Grouse Lekking Behavior In The Great Basin, Usa, Joseph L. Atkinson, Peter S. Coates, Brianne E. Brussee, Ian A. Dwight, Mark A. Ricca, Pat J. Jackson

Human–Wildlife Interactions
Expansion of human enterprise has contributed to increased abundance and distribution of common ravens (Corvus corax; ravens) across sagebrush (Artemisia spp.) ecosystems within western North America. Ravens are highly effective nest predators of greater sage-grouse (Centrocercus urophasianus; sage-grouse), a species of high conservation concern. Sage-grouse population trends are estimated using count survey data of males attending traditional breeding grounds, known as leks. We sought to investigate associations of ravens to sage-grouse lek sites and document interactions between the sage-grouse and ravens as well as those between sage-grouse and other animals observed around leks. First, we …
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado
Human–Wildlife Interactions
The number of attacks on humans by large carnivores in North America is increasing. A better understanding the factors triggering such attacks is critical to mitigating the risk of future encounters in landscape where humans and large carnivore co-exist. Since 1955, of the 632 attacks on humans by large carnivores, 106 (17%) involved predation. We draw on concepts and empirical evidence from the Predator-Prey Interaction Theory to provide insights into how to reduce predatory attacks and, thus, improve human-large carnivore co-existence. Because large carnivore-caused mortality risks for humans are comparable to those shown by other mammal species in response to …
