Tolerance Of Bearded Vultures To Human Activities: Response To Comor Et Al. (2019), Olivier Duriez, Antoni Margalida, Luc Albert, Beatriz Arroyo, Virginie Couanon, Hélène Loustau, Martine Razin, Jean-Baptiste Mihoub

Human–Wildlife Interactions

The bearded vulture (Gypaetus barbatus) is listed as vulnerable in Europe on the International Union for Conservation of Nature Red List because of population declines over multiple generations. Vulture population declines have been attributed to shooting, use of toxicants, and changes in land use, which have resulted in habitat degradation and increased anthropogenic disturbances. Concomitantly, conservation authorities have restricted practices deemed harmful to the species and have established protection buffers around occupied vulture breeding sites to mitigate the impacts of anthropogenic disturbances on breeding success. Comor et al. (2019) compared bearded vulture breeding success over 6 years within …


Modeling Migratory Nongame Birds: A Plea For Data, George M. Linz Dec 2020

Modeling Migratory Nongame Birds: A Plea For Data, George M. Linz

Human–Wildlife Interactions

The Bird Damage Management Conference held February 10–13, 2020 in Salt Lake City, Utah, USA provided a forum for professionals from across the United States to discuss and share management approaches, research strategies, policy, and messaging regarding the management of blackbirds (Icteridae), starlings (Sturnus vulgaris), corvids (Corvidae), and vultures (Cathartidae). Mathematical models were presented at the conference and subsequently discussed in a special issue of Human–Wildlife Interactions. Rapidly changing landscape variables point to the need for detailed systematic population monitoring programs with specific objectives. Nationwide periodic monitoring would provide data about changes not only in bird populations …


Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan B. Pfeiffer, Scott C. Barras, Brett G. Dunlap, Lee A. Humberg Dec 2020

Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan B. Pfeiffer, Scott C. Barras, Brett G. Dunlap, Lee A. Humberg

Human–Wildlife Interactions

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human–vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts are …


The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck Dec 2020

The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck

Human–Wildlife Interactions

Bird interactions with electric power lines can cause faults (e.g., disruption of electrical service). Faults on 500kV transmission lines in Montana, USA, which are integral to the Northwest USA power grid, became concerning during winter 2016–2017. In 2017 we found insulators contaminated with bird droppings and discovered a large nocturnal roost of common ravens (Corvus corax). To assess the potential magnitude of the impact of raven roosts on electric power transmission, we summarized fault data obtained from the Energy Management System and raven abundance data obtained from the Christmas Bird Count in central Montana from 2005 to 2020. …


Distribution And Activity Patterns Of Large Carnivores And Their Implications For Human–Carnivore Conflict Management In Namibia, Summer Fink, Richard Chandler, Michael Chamberlain, Steven Castleberry, Shannon Glosenger-Thrasher Sep 2020

Distribution And Activity Patterns Of Large Carnivores And Their Implications For Human–Carnivore Conflict Management In Namibia, Summer Fink, Richard Chandler, Michael Chamberlain, Steven Castleberry, Shannon Glosenger-Thrasher

Human–Wildlife Interactions

Human–wildlife conflicts (HWCs) are increasing globally and contributing to the decline of wildlife species. In sub-Saharan African countries such as Namibia, most of the suitable land has been or is currently being converted to crop and livestock production to support income or subsistence agriculture. These changes in land use often incur increased levels of HWCs because of crop and livestock depredation by native species. To quantify livestock predation risks posed by carnivores in Namibia, we deployed 30 trail cameras on a 6,500-ha farm in the Khomas region of Namibia from May to July 2018. We developed occupancy models to make …

Evaluation Of The Impacts Of Radio-Marking Devices On Feral Horses And Burros In A Captive Setting, Kathryn A. Schoenecker, Sarah R. B. King, Gail H. Collins Jan 2020

Evaluation Of The Impacts Of Radio-Marking Devices On Feral Horses And Burros In A Captive Setting, Kathryn A. Schoenecker, Sarah R. B. King, Gail H. Collins

Human–Wildlife Interactions

Radio-collars and other radio-marking devices have been invaluable tools for wildlife managers for >40 years. These marking devices have improved our understanding of wildlife spatial ecology and demographic parameters and provided new data facilitating model development for species conservation and management. Although these tools have been used on virtually all North American ungulates, their deployment on feral horses (Equus ferus caballus) or burros (E. asinus) has been limited. To determine if radio-collars and radio-tags could be safely deployed on feral equids, we conducted a 1-year observational study in 2015 to investigate fit and wear of radio-collars …


After Decades Of Suburban Deer Research And Management In The Eastern United States: Where Do We Go From Here?, Paul D. Curtis Jan 2020

After Decades Of Suburban Deer Research And Management In The Eastern United States: Where Do We Go From Here?, Paul D. Curtis

Human–Wildlife Interactions

State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges as they try to meet the desires of diverse stakeholder groups. Although deer management programs in urban areas differ somewhat in every state, effective management …


Monograph Reduced Box Price: Managing Human–Deer Conflicts Jan 2020

Monograph Reduced Box Price: Managing Human–Deer Conflicts

Human–Wildlife Interactions

Order form for HWI monograph, Methods for Managing Human–Deer Conflicts in Urban, Suburban, and Exurban Areas. This monograph identifies challenges and benefits associated with many human–deer conflict mitigation actions as well as methods to monitor the response of deer populations to management actions. Deer exploit urban, suburban, and exurban areas where human populations provide anthropogenic attractants, either intentionally or inadvertently, which often leads to human–deer conflicts. Mitigating actions have varying degrees of efficacy and may not be effective or accepted in every situation. Wildlife and municipal managers must work together to seek methods to reduce attractants, mitigate conflicts, and perpetuate …


Use Of Roadside Deer Removal To Reduce Deer–Vehicle Collisions, John C. Kilgo, John I. Blake, Tracy E. Grazia, Andy Horcher, Michael Larsen, Thomas Mims, Stanley J. Zarnoch Jan 2020

Use Of Roadside Deer Removal To Reduce Deer–Vehicle Collisions, John C. Kilgo, John I. Blake, Tracy E. Grazia, Andy Horcher, Michael Larsen, Thomas Mims, Stanley J. Zarnoch

Human–Wildlife Interactions

Identification of management tools to reduce the incidence of deer–vehicle collisions (DVCs) is important to improve motorist safety. Sharpshooting to reduce white-tailed deer (Odocoileus virginianus; deer) along roads has proven successful in urban situations but has not been evaluated in undeveloped areas. We used a before-after-control-impact (BACI) design to evaluate the use of sharpshooting to reduce DVCs along roads on the uninhabited U.S. Department of Energy’s Savannah River Site, South Carolina, USA, during 2011–2017. We removed 242 deer from 4 treatment roads during 2015 and 2016, with 2-year removal rates per road averaging 5.0 deer/km of road (range …
