Development Of Birdstrike Risk Assessment Procedures, Their Use On Airports, And The Potential Benefits To The Aviation Industry, J. R. Allan, A. Orosz, A. Badham, J. Bell
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Over the past 2 years, CSL has been involved in the development of formal risk assessment procedures for the birdstrike hazard to aircraft. These risk assessments have now been carried out at all BAA airports in the UK, and the impact of this process on the bird management at the different airports can begin to be assessed. The risk assessment process itself has also been refined over the same period, and calculations made to determine how the various target levels for birdstrike frequency, particularly those which, if not met, require further bird management to be undertaken, relate to absolute levels …
Improving The United States Bird Avoidance Model (Usbam) Predictive Risk Surface, Mark Alexander, Matt Bobo, Russell P. Defusco
Improving The United States Bird Avoidance Model (Usbam) Predictive Risk Surface, Mark Alexander, Matt Bobo, Russell P. Defusco
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The United States Bird Avoidance Model (USBAM) uses Geographic Information System (GIS) technology to analyze and correlate bird habitat, migration, and breeding characteristics, combined with key environmental and man-made geospatial features. The Application consists of raster grids covering the conterminous USA. The value for each grid pixel location is equivalent to the sum of the mean bird mass (in ounces), for all species present during a particular daily time period, for one of 26 2-week periods in a year. The original USBAM is a desktop application that has an intuitive design and includes separate interfaces for multiple user profiles such …
Implementation Of Gis Technology To Detect Wildlife Hazards At Airports, Michelle L. Gray
Implementation Of Gis Technology To Detect Wildlife Hazards At Airports, Michelle L. Gray
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The use of Geographic Information Systems (GIS) for displaying spatial data is a well established technique widely used by many professions, especially natural resources. Environmental and engineering departments at many civil and military airports also use GIS to aid in planning new construction and future development. These same techniques can be applied at airports to create maps that visually portray the occurrence and location of wildlife hazardous to aircraft. At Seymour Johnson Air Force Base in North Carolina, USDA Wildlife Services uses this technology to analyze and display wildlife activity on grid maps. Wildlife observations are maintained in a database …
Reported Bird Strikes At Down-State Illinois Airports, Michael W. Rapps
Reported Bird Strikes At Down-State Illinois Airports, Michael W. Rapps
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Land-use restrictions in the vicinity of airports are increasingly employed as a means to reduce bird strikes on aircraft. Yet, in the absence of controlled studies, the link between land usage and bird strikes is largely anecdotal. In seeking a connection between bird strikes and land use, the records of reported bird strikes from the years 1990-2001 were examined for 28 airports in down-state Illinois. For each airport it was noted whether land use within 6 miles of the airports included large bodies of water or wetlands, wildlife sanctuaries, golf courses, landfills, shopping venues with food concessions, or croplands. Because …
Bird Detection And Radar Wind Profilers, Scott Mclaughlin
Bird Detection And Radar Wind Profilers, Scott Mclaughlin
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Radar wind profilers (RWPs) are a very sensitive class of operational and research-grade meteorological radars designed specifically to detect clear air turbulence in the atmosphere. These systems have been designed with frequencies ranging from 50 MHz to 3 GHz and antenna sizes from about 1 m to >1 ha. Unlike NEXRAD systems, the antennas do not move or scan but rather are stationary and use phase-shifter arrangements to point the beam. Using the Doppler-shifted backscatter return, winds profiles can be measured from near the ground to as high as 20 km in 5- to 60-minute intervals. RWPs have been used …
Development Of A Portable Bird Detection Radar For Airports, Michael Hovan, William J. Hughes
Development Of A Portable Bird Detection Radar For Airports, Michael Hovan, William J. Hughes
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The development of a prototype portable bird detection radar for airports and airfields will be presented. This prototype radar is currently being developed under a partnership between the U.S. Air Force and the FAA, and is being funded under the U.S. Air Force Dual Use Science and Technology (DUST) program. Overview of the program will be given, and detailed specifications of the radar unit, and planned tests at a commercial airport will be presented. Future Plans for an integration of this type of radar into a real-time airport bird strike advisory system will be presented as well.
Need For Certification Program For Persons Conducting Wildlife Hazard Management Activities At Airports, John Ostrom
Need For Certification Program For Persons Conducting Wildlife Hazard Management Activities At Airports, John Ostrom
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
With the complexity of tools, information and resources available to airports today, there comes a need for standardization for those persons involved in Airport Wildlife Hazard Management. One approach to standardization would be the creation of a multi-level certification program to provide the basic necessary information, training and resources to anyone involved in Airport Wildlife Hazard Management. In order to create and manage this program, the basic structure of Bird Strike Committee USA (BSC USA) would need to evolve into a more formal organization. This reorganization would create the foundation for BSC USA to provide the necessary management structure and …
Increasing Air Safety At Eglin Air Force Base Through Vulture Roost Dispersal, John S. Humphrey
Increasing Air Safety At Eglin Air Force Base Through Vulture Roost Dispersal, John S. Humphrey
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Forested wetlands provide attractive roost sites for black vultures (Coragyps atratus) and turkey vultures (Cathartes aura). Vultures entering and departing roosts, however, can create hazardous conditions for pilots arriving and departing nearby airports because vultures often use the same air column as aircraft. This was the case for Eglin Air Force Base and co-located Okaloosa Regional Airport in Niceville, Florida where 260 vultures roosted in nearby Turkey Creek Nature Trail. We evaluated the effectiveness of suspending a taxidermic vulture effigy in the roost, augmented by periodic use of a handheld laser management options to alleviate these …

A New Technology To Repel Birds: The High-Intensity Acoustic Bird Dispersion System (Hiabds), Xi Baoshu, Zhou Mingjun, Wang Jingqun, Richard A. Dolbeer, Thomas W. Seamans
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
A High-intensity Acoustic Bird Dispersion System (HIABDS), invented by Professor Xi Baoshu, is a new nonlethal device for dispersing birds from airports and other locations. The device employs a unique electro-pneumatic loudspeaker which can amplify recorded wildlife vocalizations or artificial sounds of varying frequencies to high power levels and project them over long distances. The sound pressure reaches 135 dB at 10-m distance. In China, HIABDS is being used at Lanzhou Airport to disperse upland buzzards (Buteo hemilasius), whose numbers declined by 80% after 1 year of deployment. During 2001-2002, HIABDS was used at Tianjin Binhai International Airport …

Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Human-wildlife conflicts arise under a variety of circumstances and working environments. No one could have predicted the unique working environment created by events surrounding 11 September 2001. At the request of the New York City Police Department (NYPD), the Port Authority of New York and New Jersey (PANYNJ) and the New York State Department of Environmental Conservation, a team of USDA, APHIS, Wildlife Services (WS) biologists mobilized in less than 24 hours to assist officials from the NYPD, PANYNJ and the Federal Bureau of Investigation in managing birds and rodents impacting the recovery of evidence as a result of the …
Wildlife Hazard Management In Micronesia: Aviation Safety In Uncharted Territory, Daniel S. Vice
Wildlife Hazard Management In Micronesia: Aviation Safety In Uncharted Territory, Daniel S. Vice
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The islands of Micronesia support small, but growing, commercial and military aviation routes. A developing tourism industry, coupled with increased demands for military training sites, is bringing aviation traffic to remote and occasionally primitive island settings. While flight volumes are low relative to mainland settings, the nature of aviation in the islands is that of self- sufficiency and minimal infrastructure, which creates difficult flight situations. Pilots flying island routes face numerous challenges, including wildlife hazards that are generally unmitigated. Although major infrastructure and safety improvements have been made across many of the civilian airports in Micronesia, the impact of wildlife …
Bird Strikes In Courts: The Genoa Case, Valter Battistoni
Bird Strikes In Courts: The Genoa Case, Valter Battistoni
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
There have not been many court cases, be it criminal or civil, concerning accidents, or even compensation for damages, following bird strikes. Generally, those involved prefer to reach an agreement out of court. The first court sentence in Italy on this subject was pronounced by the Civil Court of Genoa in 2001. The carrier had sued a number of entities (Ministry of Transport, Airport Operator, Air Traffic Control Agency) for damages resulting from a multiple impact between a BAE 146 and a flock of gulls (Larus sp.) that occurred on 7 June 1989 at Genoa Airport. On that occasion …
Canada Goose Population Management At The Minneapolis-St. Paul International And Downtown St. Paul Airports, James A. Cooper
Canada Goose Population Management At The Minneapolis-St. Paul International And Downtown St. Paul Airports, James A. Cooper
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
A Canada goose (Branta canadensis) control program was initiated at the Minneapolis-St. Paul International Airport (MSP) in 1984, and at the Downtown St. Paul Airport (STP) in 1994. Flightless geese >16 km from these airports were trapped (MSP 1,734; STP 1,397), neck-banded (MSP 1,047; STP 502), and observed and counted weekly in fall at 22 and 6 locations >5 km from MSP and STP, respectively. Efficacy was also measured by observing fall goose flights through the operations airspace in 1984-1987 and 1998-2001 (MSP), and 1994-2001 (STP). Based on neckband origin of birds observed >2 km from the airfields, …
Monte-Carlo Simulation Of Birdstrike To Support Rule Making For Large Birds, Julian M. Reed
Monte-Carlo Simulation Of Birdstrike To Support Rule Making For Large Birds, Julian M. Reed
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
A clear need was established by the aero-engine manufacturers and the certifying authorities for a re-assessment of the published rules governing engine certification for large flocking birds. A task group was set up to address this need at the beginning of 2000. Early in this program, it was determined that a statistical approach to the rule making was required and the Monte-Carlo technique was proposed and accepted. This paper discusses the implementation of the Monte-Carlo technique to simulate bird strike events from the Rolls-Royce viewpoint and describes the various refinements that have been made in order to ensure an adequate …
Aircraft Engines And Large Flocking Birds, Richard Parker
Aircraft Engines And Large Flocking Birds, Richard Parker
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
This paper will present a summary of the results of the ARAC (engine) Bird Ingestion Phase II rule making effort. The effort was to evaluate the hazard to transport category aircraft, of large flocking birds, and to revise the engine certification requirements as appropriate. The paper will discuss the revision to engine certification requirements. It will also discuss the recommendation of the task group regarding the importance of continuing effort for bird control at the airport.
A Paradigm Shift In Bird Strike Prevention By The Israeli Air Force, Nicholas B. Carter, Eyal Cohen
A Paradigm Shift In Bird Strike Prevention By The Israeli Air Force, Nicholas B. Carter, Eyal Cohen
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Over the past 20 years, the Israeli Air Force (IAF) has focused attention in bird strike prevention on collisions between aircraft and migrating birds during low-level flight operations. Only in the last 2 years has the IAF begun to tackle the problem of reducing bird-aircraft collisions at or near airfields. A dramatic shift in thinking has led the IAF to initiate complete wildlife control programs at its airbases, featuring the employment of border collies and wildlife control officers to help eliminate the risk of wildlife collisions within the control zone (CTR) of each airfield. As a crucial component of this …
Evaluation Of Electrobraid Fencing As A Deer Barrier, Thomas W. Seamans, Zachary J. Patton, Kurt .. Vercauteren
Evaluation Of Electrobraid Fencing As A Deer Barrier, Thomas W. Seamans, Zachary J. Patton, Kurt .. Vercauteren
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Increasing white-tailed deer (Odocoileus virginianus) populations in North America have lead to direct threats to public safety as well as agricultural losses. Fencing is often used to keep deer from causing damage at both airports and agricultural areas. Tall, chain-link fences have been used successfully but are often prohibitively expensive. Electric fences have potential to offer a less expensive alternative. We tested a new electric fence design marketed under the name ElectroBraid. This fence, comprised of 0.6-cm polyester rope with copper wire woven into it, is carried on frangible, fiberglass posts set at 15-m intervals. From January to …
Birdstrike Identification (Poster), Carla Dove
Birdstrike Identification (Poster), Carla Dove
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Identification of feather evidence retrieved from birdstrikes provides essential information that allows airfield managers, engineers, pilots and government agencies to work together to prevent damaging birdstrikes. Knowing the identity of the birds that are causing problems is the first step in formulating a plan to discourage birds from interfering with aviation safety. The feather identification process is complex and involves cleaning feather material, microscopic examination, and whole feather comparisons with specimens in a museum collection. This poster presents the feather identification technique and provides information to various agencies on how and where to send birdstrike remains for identification.
Status Of North American Canada Goose Populations (Poster), John L. Seubert
Status Of North American Canada Goose Populations (Poster), John L. Seubert
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
North American Canada goose (Branta canadensis) populations continue to increase, causing potentially greater hazard to aviation. There is greater interest by biologist and aviation interests in monitoring the status of these populations because of the increasing number of Canada goose strikes to aircraft. Waterfowl in North America are managed in four administrative flyways – the Atlantic, Mississippi, Central, and Pacific. Goose numbers in these flyways are based on mid-winter or breeding period counts. The Canada goose count for North America in 2000 was 5,728,000—61% were the large resident geese. The resident component of the population has increased more …

Managing Nature In Today's World, Walter E. Howard
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The objective of my talk is to help airport authorities better understand the turmoil they encounter when managing birds and other wildlife populations. Many are reluctant to manage birds and mammals because they know that it will inevitably stir up controversy. Especially this is true when the program includes lethal means. Many people think all problems can be resolved by using non-lethal frightening devices or by live-trapping offending animals and relocating them away from airports. There are some sound arguments as to why it is biologically, ecologically and ethically proper to even use lethal means to resolve some airport wildlife …
Even With Good Equipment, Experienced Manpower Is Necessary, Nigel Horton
Even With Good Equipment, Experienced Manpower Is Necessary, Nigel Horton
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Maximized efficiency and quality assurance of equipment is essential to both the manufacturer and the end-user. Quite uniquely, one UK manufacturer of bird control equipment sought the views of the aerodrome bird control staff who used it. A simple tick-box questionnaire, designed by an independent biologist, was sent to each aerodrome and 37 returned completed forms, representing about half of known users in the UK. A simple subjective analysis of these produced some unexpected results that are presented here. The survey was not dissimilar to the original trials of bird distress calls on RAF airfields undertaken during the 1960's, thus …

Avian Hazard Control In Brazil: Essential Role Of The Aeronautical Accidents Prevention And Investigation Center - Cenipa, Luiz Claudio Magalhaes Bastos
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Brazil built one of the world’s largest aeronautical infrastructures. The airport net is distributed along its vast territory, which shows a tremendous ecosystem variety. Having a large civilian aircraft fleet and also running second after Venezuela in catalogued bird species, Brazil has had problems related to bird strikes. Nevertheless, Brazil is made up of 26 States plus the Federal District. Thus, besides the Union Government, each state holds its own government structure. The states are divided into counties that also have their own administrative structure. The jurisdiction of each level of government is established by the Federal Constitution, laws and …

Assessing Bird Strike Hazards In Coastal Wetlands Through Field Experiments, John Ledbetter, John Gray
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Santa Barbara Municipal Airport (SBA) is located in and adjacent to Goleta Slough, a large coastal salt marsh with limited tidal circulation. Various government and non-government agencies are pursuing a long-term project to restore the historic tidal circulation to the slough to improve ecological conditions. SBA recently completed a study to assess feasibility of conducting a controlled field experiment in the slough to evaluate the relationship between bird strike hazards and the presence of tidal and non-tidal wetlands near the airfield. The study indicated that a limited field experiment, in which new estuarine marsh areas are temporarily restored, would provide …
Automated Haze Systems With Methyl Anthranilate Eliminate Nuisance Birds In Aviation Hangars, Warehouses, Airports, Bruce E. Vergote
Automated Haze Systems With Methyl Anthranilate Eliminate Nuisance Birds In Aviation Hangars, Warehouses, Airports, Bruce E. Vergote
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Automated haze systems (The BirdHazer) combined with Methyl Anthranilate (MA) is proven effective and cost efficient as an application method for eliminating nuisance birds in aviation hangars, warehouses, and airport facilities. Proper placement of the BirdHazer system which is based on air flow circulation allows to deliver a clean, dry haze, producing a mean droplet diameter size of 5 microns , which also eliminates the possibility of permeation and any settled residue. Three preliminary test studies were successfully completed at 2 dairy barn locations, and a salt storage warehouse. The fourth testing site was conducted at a maintenance hangar at …

Responses Of Captive Birds To Candidate Perching Deterrents On Faa Llwas Units, Michael L. Avery, Ann C. Genchi
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
Successful operation of the FAA’s Low-Level Windshear Alert System (LLWAS) depends largely on birds not perching on the wind-sensing units which are installed atop poles 40-45 m tall. Because new LLWAS units will be erected at airports throughout North America, anti- perching devices must deter numerous avian species ranging widely in body size and behavioral pattern. To determine the most promising devices, we conducted pen trials with brown-headed cowbirds, fish crows, barred owls, great horned-owls and black vultures. Birds were given free access to an unmodified sensor unit mounted on a tripod for 24 hours, during which the only alternative …
“Birdstrike” – What’S The Word? (Poster), Carla Dove
“Birdstrike” – What’S The Word? (Poster), Carla Dove
Bird Strike Committee-USA/Canada Joint Annual Meeting: 4th (2002)
The word(s) “bird strike”, “bird-strike”, or “birdstrike” has been used inconsistently throughout the literature for as long as birds have been colliding with aircraft. A recent search of peer-reviewed articles in the Zoological Record and Biological Abstracts dating back to 1969 resulted in 52 articles that pertained to bird-aircraft collisions. Of those, 67% used two words (bird strike); 22% used a hyphenated word (bird-strike); 5.5% used one word (birdstrike), and 5.5% actually used both two words and the hyphenated version in the same paper! A brief glance through the proceedings and abstracts of recent Bird Strike Committee Meetings also exemplifies …
