Human–Wildlife Interactions
Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …
Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Human–Wildlife Interactions
Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …
Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Human–Wildlife Interactions
Three recent publications have estimated the number of birds killed each year by wind energy facilities at 2012 build-out levels in the United States. The 3 publications differ in scope, methodology, and resulting estimates. We compare and contrast characteristics of the approaches used in the publications. In addition, we describe decisions made in obtaining the estimates that were produced. Despite variation in the 3 approaches, resulting estimates were reasonably similar; about a quarter- to a half-million birds are killed per year by colliding with wind turbines.
Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May
Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May
Human–Wildlife Interactions
Mitigating impacts of wind energy development on wildlife is important for conservation and public acceptance of this energy source. We provide an overview of approaches to mitigate impacts of onshore wind energy development on wildlife, following steps in the mitigation hierarchy, including avoidance, minimization, and compensatory mitigation. Planning and avoiding predicted high-risk areas is fundamental to reduce impacts on birds and bats. Contrary to avoidance, once facilities are built, options to minimize impacts need to be tailored to species at the specifc site, and can be limited especially for bats. Curtailing wind turbine operations is the only approach proven effective …
Modification Of Net Configurations Of The Coda Netlauncher® To Enhance Bird Capture, Amanda M. Prisock, Brian S. Dorr, James C. Cumbee
Modification Of Net Configurations Of The Coda Netlauncher® To Enhance Bird Capture, Amanda M. Prisock, Brian S. Dorr, James C. Cumbee
Human–Wildlife Interactions
We modified and evaluated capture nets fired from the Coda Netlauncher® as a tool for capturing various avian species. We modified the netlauncher by using customized nets to maximize the area of the capture zone. We captured 137 birds, comprising 12 species, in 23 attempts between July 2008 and October 2009 using this method. Capture success rates varied from 25 to 69% were comparable to success rates reported for other capture methods for these species. However, individual capture success for different net configurations varied greatly from 3 to 65%. Minimal injuries and 2 bird fatalities were reported. The netlauncher, using …
Bird Consumption Of Sweet And Tart Cherries, Catherine A. Lindell, Rachael A. Eaton, Erin M. Lizotte, Nikki L. Rothwell
Bird Consumption Of Sweet And Tart Cherries, Catherine A. Lindell, Rachael A. Eaton, Erin M. Lizotte, Nikki L. Rothwell
Human–Wildlife Interactions
Identifying species responsible for crop damage is an important first step in developing management strategies. Previous studies have surveyed bird species flying through cherry orchards but have not documented which species were consuming cherries. We conducted traditional surveys and behavioral observations in orchards of sweet cherries (Prunus avium) and tart cherries (Prunus cerasus) in Michigan during 2010 to compare results from the 2 techniques. American robins (Turdus migratorius) were detected most frequently during sweet cherry surveys, while behavioral observations showed that cedar waxwings (Bombycilla cedrorum) consumed more sweet cherries than did robins. …
Rock Pigeon Use Of Livestock Facilities In Northern Colorado: Implications For Improving Farm Bio-Security, James C. Carlson, Larry Clark, Michael F. Antolin, Mo D. Salman
Rock Pigeon Use Of Livestock Facilities In Northern Colorado: Implications For Improving Farm Bio-Security, James C. Carlson, Larry Clark, Michael F. Antolin, Mo D. Salman
Human–Wildlife Interactions
Rock pigeons (Columba livia) have been implicated in the spread of pathogens within commercial livestock facilities. Currently, there is no data characterizing pigeon habitat use and movement patterns within and among commercial livestock facilities. To better understand the capacity for pigeons to spread pathogens, we used radio-telemetry techniques to estimate the home-range, travel distance, activity, and habitat use of pigeons roosting on and off dairies and feedlots in western Weld County, Colorado. Our observations suggest that pigeons roosting on (resident) and off (nonresident) livestock facilities use habitat differently. Nonresident pigeons used larger home-range areas than did resident pigeons. …
Disturbance As Restoration In The Intermountain Sagebrush Steppe: Effects On Non Target Bird Species, Russell Edward Norvell
Disturbance As Restoration In The Intermountain Sagebrush Steppe: Effects On Non Target Bird Species, Russell Edward Norvell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Changes in shrubsteppe passerine bird habitat associations in response to disturbance were investigated at multiple temporal and spatial scales. Spatial measures incorporated the effects of area at different ecological scales (nest site, territory, and landscape) to include ecologically meaningful extents. Temporal measures included seasonal and annual effects, and were designed to detect lagged responses should they occur. Local-to-landscape scale effects of mechanical restoration treatments on local extirpation and abundances of nine species indicated most were insensitive to changes in habitat quality, while abundance models showed only broad declines. Changing the availability of nesting habitat on both the attractiveness and quality …
A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark
A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark
Human–Wildlife Interactions
Cattle are the main reservoir for human infection by pathogenic Escherichia coli and Salmonella enterica. To prevent entry of these foodborne pathogens into the human food chain, management factors at the farm level must be identified and controlled. External sources of contamination, such as birds, should be considered as potential sources of transmission over long distances. In this review, we focus on the epidemiology of infection by E. coli and S. enterica and the consequences of birds acting as disseminators of these pathogens at dairy farms in terms of cattle health and the subsequent effects on human health.
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Human–Wildlife Interactions
Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most vulnerable, and control methods employed. Bird problems varied by island, but cardinals ( …

Relationships Among Birds, Willows, And Native Ungulates In And Around Northern Yellowstone National Park, Sally Graves Jackson
Relationships Among Birds, Willows, And Native Ungulates In And Around Northern Yellowstone National Park, Sally Graves Jackson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Although the impacts of livestock and human activities on riparian zones and associated wildlife have been well documented, little is known about the impacts that browsing by large native ungulates such as elk and moose may have. In the northern Yellowstone area, some willow stands experience intense browsing by elk and moose whereas others experience medium or very low amounts of browsing. The objectives of this study were (1) to compare the species and densities of birds among willow stands that have experienced different intensities of browsing by native ungulates, (2) to measure the relationship between five species of birds …
Birds Of A Great Basin Sagebrush Habitat In East-Central Nevada, United States Department Of Agriculture, Forest Service
Birds Of A Great Basin Sagebrush Habitat In East-Central Nevada, United States Department Of Agriculture, Forest Service
Wildlife Conservation and Management
Breeding bird populations ranged from 3.35 to 3.48 individuals/ha over a 3-year study conducted from 1981 to 1983. Brewer's sparrows, sage sparrows, sage thrashers, and black-throated sparrows were numerically dominant. Horned larks and western meadowlarks were less common. Results are compared with bird populations in Great Basin sagebrush habitats elsewhere in the United States.
