Prey Manipulation As A Management Strategy At An Inland South African Airport, Ordino Kok Aug 2006

Prey Manipulation As A Management Strategy At An Inland South African Airport, Ordino Kok

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Prey manipulation was investigated as a means of reducing the bird hazard at the Bloemfontein airport, central South Africa. From January 1985 to December 2005 approximately 7,000 individuals representing 55 bird species which, potentially, posed a threat to aviation, were collected at the airport. Numerically the crowned plover (Vanellus coronatus), blacksmith plover (V. armatus), lesser kestrel (Falco naumanni), white-winged korhaan (Eupodotis afraoides) and double-banded courser (Smutsornis africanus) in order of importance constituted more than 90% of the total sample. Based on stomach analyses harvester termites (Hodotermes mossambicus) comprise the dominant food source of all five species concerned. Experimentally a significant …

Airport Canopies Become Starling Roosts – Two Airport Case Studies, Sharon Gordon, Randolph J. White Aug 2006

Airport Canopies Become Starling Roosts – Two Airport Case Studies, Sharon Gordon, Randolph J. White

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

For aesthetic purposes and to protect passengers from weather, airports often construct glass canopies over roadways. These structures can provide roosting opportunities for large numbers of European starlings, which can pose a significant strike hazard to aircraft. Both Portland International Airport (Oregon) and Cleveland Hopkins International Airport (Ohio) have recently had to address this problem, using different methods to find an effective solution. Portland installed 200,000 square feet of exclusion netting in its large canopy structure while Cleveland Hopkins used a combination of tree removal and harassment to disperse their starling roost. These two cases demonstrate the importance of considering …

Overhead Grid Line Systems To Exclude Waterfowl From Large Bodies Of Water, Tony Duffiney Aug 2006

Overhead Grid Line Systems To Exclude Waterfowl From Large Bodies Of Water, Tony Duffiney

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

The presence of birds at retention/detention basins on or adjacent to an airport increases the probability of experiencing a wildlife strike. Overhead gridline systems have proven effective for reducing the presence of birds on small water bodies. While there are several grid materials available to address bird hazards associated with small basins, the list of options decreases quickly as the distance to be spanned increases. The Michigan Wildlife Services program (WS) tested five types of grid material on three large detention basins to determine which materials could span up to 675 meters (2214.5 feet) without center supports. Additionally, the line …

Bat Strikes: Past, Present, And Future, Suzanne C. Peurach Aug 2006

Bat Strikes: Past, Present, And Future, Suzanne C. Peurach

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

All but a few North American bats are insectivorous and weigh less than 35 g, but this diverse group of mammals also contains species with wingspans up to 2 meters and weighing a kg or more. Even small-bodied bats can cause considerable damage when encountered in swarms. When aircraft head into new territory and encounter strikes, the ability to identify the species of bat struck is paramount to preventing future strikes. Identifications of bats from fragmentary evidence are made by comparing samples recovered from aircraft with specimens housed in the Smithsonian Institution’s National Museum of Natural History. This collection, worldwide …

Nicarbazin: An Avian Reproductive Inhibitor For Pigeons And Geese, Christi A. Yoder, Michael L. Avery, Erick Wolf Aug 2006

Nicarbazin: An Avian Reproductive Inhibitor For Pigeons And Geese, Christi A. Yoder, Michael L. Avery, Erick Wolf

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Nicarbazin (NCZ) is an anticoccidial drug routinely used in the poultry industry. When fed to laying hens, NCZ impacts reproduction by either reducing hatchability of eggs or reducing rate of egg laying. Initial laboratory tests were conducted with mallards (Anas platyrhynchos) to determine the efficacy of NCZ as a waterfowl contraceptive. Hatchability was 26% for mallards fed 34 mg NCZ/kg body weight (500 ppm in feed) for 14 days compared to 55% for control mallards. Based on these results, two field studies, one each in Oregon and Colorado, were conducted with Canada geese (Branta canadensis), which showed a 50-56% decrease …

Canada Goose Populations And Strikes With Civil Aircraft: Positive Trends For Aviation Industry, Richard A. Dolbeer, John L. Seubert Aug 2006

Canada Goose Populations And Strikes With Civil Aircraft: Positive Trends For Aviation Industry, Richard A. Dolbeer, John L. Seubert

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Canada goose (Branta canadensis) populations in North America are subdivided into “migrant-goose” and “large-goose” populations. The “large-goose” populations consist primarily of flocks that are non-migratory (hereafter referred to as resident geese). Estimated migrant and resident geese numbers in the four flyways (Atlantic, Mississippi, Central, and Pacific) are based on mid-winter or breeding period counts. The overall Canada goose population increased five fold from 1970 (1.08 million) to 2005 (5.01 million). Most of this overall increase was due to a 15-fold increase in the population of resident geese (from 0.2 to 3.4 million), especially during the 1990s when the …

The Use Of Radar To Augment Visual Observations In Wildlife Hazard Assesments, Robert C. Beason, Michael J. Begier Aug 2006

The Use Of Radar To Augment Visual Observations In Wildlife Hazard Assesments, Robert C. Beason, Michael J. Begier

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Assessing wildlife hazards to aviation in the airport environment is typically initiated by conducting a Wildlife Hazard Assessment (WHA). Ecological relationships between wildlife populations and habitat are usually discerned through observations during the course of one annual cycle. Although proximate hazards, on the airport, are well defined during the WHA process, off-airport features also can attract wildlife. Wildlife species can transit airport property traveling to and from habitat attractants. During a WHA, common wildlife sampling techniques are employed to determine species, their approximate numbers, and through association an index of potentially attractive habitat. Continuous observations could provide a more complete …

An Acoustic / Radar System For Automated Detection, Localization, And Classification Of Birds In The Vicinity Of Airfields, Bruce Stewart, Sebastian Pascarelle, John Pinezich, T. Adam Kelly, Andreas Smith, Robert Maher

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Bird-aircraft collisions present a significant threat to military and commercial aircraft, and as bird populations and air traffic continue to grow, and airport/airbase operations continue to expand, the problem will steadily get worse. To help mitigate bird strike hazards, we propose a multi-sensor system consisting of ground radar and acoustic sensors that can directly monitor bird activity and provide an alert when a threat condition occurs. Radar offers a large detection range and the ability to detect in all weather conditions, while acoustic sensors allow the ability to detect targets in the midst of clutter and add the capability to …

The Airport Is Not A Wildlife Refuge!, Russell P. Defusco, Robert L. Dogan Aug 2006

The Airport Is Not A Wildlife Refuge!, Russell P. Defusco, Robert L. Dogan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Airports must eliminate or minimize bird and other wildlife attractants to maintain safe operating conditions. Unfortunately, all too often this is not the case. Outside pressure, political or economic decisions, and lack of awareness of appropriate management practices lead to many airports becoming safe havens for wildlife by accident or incredibly, by design. Airport tenants, airlines, or other users are often at the mercy of the airport operator or owner and believe they have little control over the situation where they operate. Proper habitat management is the basis for any wildlife or bird strike reduction program. Vegetation management is at …

Disposal Of Bio-Solids At Airports: Increased Wildlife Hazards To Aviation Or Not?, Michael J. Begier, Brian E. Washburn Aug 2006

Disposal Of Bio-Solids At Airports: Increased Wildlife Hazards To Aviation Or Not?, Michael J. Begier, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Airports often times employ different land uses on their airfields to generate or save funds. The application of bio-solids is one such use. Questions concerning this practice and its compatibility with safe aircraft operations arise; however, little information exists concerning this issue. FAA regulations and technical guidance do not currently prohibit this practice on airfields. Marine Corps Air Station Cherry Point, located in North Carolina, has applied treated bio-solids to portions of the airfield over the past 14 years; this program is anticipated to continue into the future. During 2003–2005, we conducted a study to compare plant community dynamics and …

The Impacts Of Habitat Manipulation On The Ring-Necked Pheasant Population At Cck Air Force Base In Taiwan, Shaopin Yo, Kuo-Bin Lin

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Ring-necked pheasant is an endemic subspecies of Taiwan. The main habitat of the bird is the grass lands at the low elevation in Taiwan. The population has been threatened due to the fast agricultural development and human disturbance at their habitats in Taiwan. However, the airfield of CCK Air Force Base has maintained a healthy pheasant population due to the large scale of grass lands without much human disturbances. Several bird strikes occurred at CCK air force base due to the foraging activities of ring-necked pheasant across the runway of the airfield. The main purpose of this study is to …

Response Of Birds To Aircraft Lighting: Implications For Reducing Bird-Aircraft Collisions, Bradley F. Blackwell, Thomas W. Seamans, Scott Philiben Aug 2006

Response Of Birds To Aircraft Lighting: Implications For Reducing Bird-Aircraft Collisions, Bradley F. Blackwell, Thomas W. Seamans, Scott Philiben

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Is there a means by which birds might better discern aircraft position and speed, so as to reduce collisions? Vision is a primary and highly developed sensory pathway in birds, and recent work has shown that light can be an effective tool as a repellent and, potentially, as an alert. Given that bird-aircraft collisions (hereafter referred to as bird strikes) cost the commercial aviation industry world-wide in excess of $1.28 billion annually (U.S. $), the incorporation of ecologically salient light cues into the design of aircraftmounted lighting is one means by which airlines might reduce bird strikes. We will report …

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

An effective definition of a bird strike is the basis for quantifying the scale of bird hazard problems. Here we present a working definition of a bird strike, which in turn forms the basis of an analysis of 32 years’ data collected at Dublin Airport, Ireland. A variety of datasets are analysed including the number of bird strikes per ten thousand aircraft movements, the mass of the bird species being struck, the time of year at which bird strikes occur and the dimensions of the aircraft utilising the airfield. In addition, we have analysed the mean number of strikes per …

Birds Commuting Across The Runway: How To Reduce This Bird Strike Risk?, Albert De Hoon, Luit Buurma Aug 2006

Birds Commuting Across The Runway: How To Reduce This Bird Strike Risk?, Albert De Hoon, Luit Buurma

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Not only birds residing at airports, but also birds commuting daily across the runways from and to places outside the airport boundaries, may pose a threat to departing and landing aircraft. Species such as gulls, geese, cormorants, ducks, flamingos, starlings and crows often have foraging sites that can be miles away from their breeding or roosting places. Dealing with those commuting birds that pass over airports on a daily basis is complicated because their roosting, breeding, and foraging sites do not belong to the airport’s property. The solution to the problem becomes even more complex when these sites are part …

Reduction Of Risk: A Flight Crew Guide To The Avoidance And Mitigation Of Wildlife Strikes To Aircraft, Paul Eschenfelder, Steve Hull

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Each year the world’s airlines lose between $1 billion to $2 billion due to wildlife strikes to aircraft. This is roughly the same level of loss as the carriers pay out each year for lost luggage. One US airline cites its losses at $2 million a month due to engine ingestion alone. The last several years have seen both hull losses to air carrier aircraft and lesser damage caused by such actions as loss of control and runway excursions. Wildlife strike mitigation is a defense in depth: airplane certification/construction standards; action by airport operators to minimize wildlife on and around …
