Bird Strikes And Aircraft Fuselage Color: A Correlational Study, Esteban Fernández-Juricic, Jimmy Gaffney, Bradley F. Blackwelll, Patrice Baumhardt

United States Department of Agriculture Wildlife Services: Staff Publications

Collisions between birds and aircraft (bird strikes) pose safety risks to the public, cost airports and airlines money, and result in liability issues. Recent research suggests that aircraft visibility could be enhanced to increase detection and avoidance by birds. We questioned whether aircraft color scheme might play a role in bird-strike frequency. We used public records of bird strikes along with information on flights that were gathered by federal agencies in the United States. We estimated the bird-strike rates and compared them among airline companies using different fuselage color schemes, while controlling for aircraft type. Using an avian vision modeling …

Livestock And Domestic Dog Predations By Wolves In Michigan, Justin L. Edge, Dean E. Beyer Jr., Jerrold L. Belant, Mark J. Jordan, Brian J. Roell

Human–Wildlife Interactions

Wolves (Canis spp.) have recolonized the Great Lakes region and expanded into agricultural areas where there is increasing concern of conflict with livestock. We documented 121 wolf predation events on captive or domestic animals in the Upper Peninsula (UP) of Michigan between April 1996 and April 2009. We investigated the relationship between annual wolf abundance and predation events, seasonality of predations on livestock, and the association between previous winter severity and predations on livestock. The annual number of predations on livestock increased with wolf abundance, and overall, predations on cattle and calves increased during calving season. We observed a …


Using Whatman Fta® Cards To Collect Dna For Bird-Strike Identifications, Carla J. Dove, Nor Faridah Dahlan, Marcy A. Heacker, James F. Whatton Jan 2011

Using Whatman Fta® Cards To Collect Dna For Bird-Strike Identifications, Carla J. Dove, Nor Faridah Dahlan, Marcy A. Heacker, James F. Whatton

Human–Wildlife Interactions

Identification of species of birds is fundamental to implementation of all management and mitigation issues involving bird–aircraft collisions (bird strikes). Methods of identifying bird remains have recently been enhanced to include the use of molecular techniques but the degraded condition of the fi eld sample remains problematic. The Whatman FTA® card is a novel way to instantly fi x DNA and inhibit degradation of DNA samples post-collection. During 2008–2009, we analyzed >200 FTA cards containing tissue blots, body fluids, or blood samples from bird strikes to evaluate the performance of these cards in real-time situations. We analyzed the success of …
