New regulatory restrictions have been placed on the use of some second-generation anticoagulant rodenticides in the United States, and in some situations this action may be offset by expanded use of first-generation compounds. We have recently conducted several studies with captive adult American kestrels and eastern screech-owls examining the toxicity of diphacinone (DPN) using both acute oral and short-term dietary exposure regimens. Diphacinone evoked overt signs of intoxication and lethality in these raptors at exposure doses that were 20 to 30 times lower than reported for traditionally used wildlife test species (mallard and northern bobwhite). Sublethal exposure of kestrels and …

Using Bird Strike Information To Direct Effective Management Actions Within Airport Environments, Todd J. Pitlik, Brian E. Washburn

Wildlife--aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Many bird species, especially gulls, are very difficult to manage within airport environments as many traditional methods (e.g., trap and remove from the airport) can be relatively ineffective due to the birds’ various activities on airports (e.g., feeding, loafing, and flying). Such challenges have greatly impacted the Los Angeles International Airport and the Van Nuys Airport, as documented through historical bird strike records collected since 1990. Using information contained in these bird strike records, USDA APHIS Wildlife Services personnel conducted strategic planning efforts to reduce the risk of bird …
Association Of Wild Bird Density And Farm Management Factors With The Prevalence Of E. Coli O157 In Dairy Herds In Ohio (2007–2009), N. Cernicchiaro, D. L. Pearl, S. A. Mcewen, L. Harpster, H. J. Homan, G. M. Linz, J. T. Lejeune

Our objective was to determine the role that European starlings (Sturnus vulgaris) play in the epidemiology of Escherichia coli O157:H7 in dairy cattle. We visited 150 dairy farms in Ohio twice during summer and fall months from 2007 to 2009. Fresh faecal pats from 30 lactating cows were collected during each visit. Information on farm management and environmental variables was gathered through a questionnaire administered to the farm owner. The number of starlings observed on the farm was also recorded. Approximately 1% of dairy cattle and 24% of farms were positive for E. coli O157. Risk factors associated …
Are Turf-Type Tall Fescue Cultivars Useful For Reducing Wildlife Hazards In Airport Environments?, Brian E. Washburn
Are Turf-Type Tall Fescue Cultivars Useful For Reducing Wildlife Hazards In Airport Environments?, Brian E. Washburn

Wildlife-aircraft collisions pose a serious risk to aircraft and cost civil aviation over US$1 billion worldwide annually. Habitat management within airport environments is the most important long-term component of an integrated approach to reduce the use of airfields by hazardous wildlife. Recent research has demonstrated that Canada geese avoid foraging on endophyte-infected tall fescue; consequently, this turfgrass might be useful in airfield revegetation and seeding projects. Although some research evaluating commercially available tall fescue cultivars on airfields has been conducted, additional information is needed to determine if tall fescue cultivars might be viable for airfields in various regions of the …
The Net Benefits Of Controlling Bird And Rodent Pests In Wine Grape And Avocado Production, Aaron M, Anderson, Katy Kirkpatrick, Stephanie A. Shwiff
The Net Benefits Of Controlling Bird And Rodent Pests In Wine Grape And Avocado Production, Aaron M, Anderson, Katy Kirkpatrick, Stephanie A. Shwiff

The objective of this analysis was to estimate the net benefits of controlling bird and rodent pests in California production of wine grapes and avocados. These two crops were chosen because of the expected differences in types and extent of pest damage and methods of pest control used by growers, as well as their importance in California agriculture. A web-based survey was designed to capture grower experiences with current levels of pest damage and their expectations about damage levels without control. Information on the methods of pest control and associated costs was also solicited from growers. We obtained 83 responses …
