Effects Of Location And Phase Of Flight On The Behavioral Responses Of Birds To Aircraft: Preliminary Observations, T. C. Kelly, M. J. A. O'Callaghan, P. D. Bourke, L. Buurma, R. Bolger

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Based on an earlier classification of avoidance movements shown by birds to moving aircraft (Kelly et al. 2001), we have studied the evading maneuvers of the rook (Corvus frugilegus) in relation to the phase of flight of air traffic at Dublin Airport, Ireland. The percentage of individuals which did not show avoidance movements was almost identical for approach/landing and take-off /climb-out movements. However, the nature of the avoiding-response in relation to the phase of flight was different. Thus 78% of responses were “Simple” in the approach/landing flight phase whereas only 5% were in this category during take-off. On …

Efficacy Of Aircraft Landing Lights In Stimulating Avoidance Behavior In Birds, Bradley F. Blackwell, Glen E. Bernhardt Oct 2002

Efficacy Of Aircraft Landing Lights In Stimulating Avoidance Behavior In Birds, Bradley F. Blackwell, Glen E. Bernhardt

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

A potential non-lethal technique to reduce bird-aircraft collisions, aircraft-mounted light, has been considered for nearly 3 decades, but has received no formal research as to its efficacy. We tested the hypothesis that during daylight hours birds exposed to an approaching vehicle exhibiting pulsing landing lights would react more quickly than birds experiencing an on-coming vehicle with non-pulsing (steady) or no lights (control). We used the PulseliteTM system (Precise Flight, Inc., Bend, Oregon, USA), an early recognition lighting system that allows an aircraft pilot to pulse the landing, taxi, or forward-facing recognition lights, and 2 General Electric sealed-beam 250-W aircraft …

Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica Dewey Oct 2002

Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica Dewey

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Birds pose serious hazards at U.S. airports. Raptors are hazardous to aircraft safety due to their size, hunting behavior, and hovering/soaring habits. Abundant food sources, open space, and availability of perches at or near airports contribute to ideal hunting opportunities for many raptors. The ability to directly manage raptor populations is limited by the Migratory Bird Treaty Act. Reduction of small mammal populations at an airport may decrease raptor populations in the area and therefore, reduce the risk that raptors pose to aircraft. Rodents can be managed by population management or by habitat management. Reduction of small rodent populations can …

Efficacy Of Translocation Of Red-Tailed Hawks From Airports, Laurence M. Schafer, John L. Cummings, John A. Yunger, Kirk E. Gustad Oct 2002

Efficacy Of Translocation Of Red-Tailed Hawks From Airports, Laurence M. Schafer, John L. Cummings, John A. Yunger, Kirk E. Gustad

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Raptor translocation from airport environments is a management strategy that has been recommended and used in attempts to reduce aircraft strikes. However, supportive data are lacking about optimal translocation distance and direction, return rate, post-translocation fate and overall efficacy of the technique. We conducted a study from 1 December 1999 to 28 February 2002, which included satellite telemetry, to address these issues of raptor translocation at a Midwest Airport. Two hundred and fourteen red-tailed hawks (Buteo jamaicensis) were translocated to 12 sites in Illinois, between 59 and 242 km from the airport. Thirty-four after-hatch-year (AHY) individuals were fitted …

Attracting Arctic Foxes To Relocate A Gull Colony At Keflavik International Airport (Poster), Pall Hersteinsson, Gundmundur Orn Jonsson

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

The Lesser Black-backed Gull (Larus fuscus) colony at Keflavik International Airport has grown from around 1,000 pairs in 1975 to over 20,000 pairs in the early 1990s and to around 30,000 pairs in 2000. The colony is considered a serious hazard to both military and civil air traffic. The population of arctic foxes (Alopex lagopus), the only predator in Iceland capable of preying on these gulls, was very small in this area from the late 1950s until the mid-1980s. A decade ago we noted that the location of the colony had shifted away from an arctic …

Identification Of Batstrikes (Poster), Suzanne C. Peurach Oct 2002

Identification Of Batstrikes (Poster), Suzanne C. Peurach

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Identification of fragmentary evidence such as hairs, bones, and claws that have been recovered from United States Air Force (USAF) aircraft has been undertaken by the Biological Survey Unit (USGS) for the last 5 years. The results of these investigations may be useful in preventing future damaging batstrikes. Examination of batstrikes may also provide valuable information to the scientific research community about patterns in bat migration, flight altitudes, and times of flight. Positive identifications are made by comparing unknown samples with the collection of museum specimens housed in the Smithsonian Institution’s National Museum of Natural History. Macroscopic characters such as …

Status Of North American Canada Goose Populations (Poster), John L. Seubert Oct 2002

Status Of North American Canada Goose Populations (Poster), John L. Seubert

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Animal Ambush At The Airport: The Extent And Nature Of Non-Bird Wildlife Strikes With Civil Aircraft, Usa, 1990-2001 (Poster), Sandra E. Wright, Richard A. Dolbeer

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Birds have long been recognized as a serious threat to aviation safety. However, other wildlife (mammals and reptiles) can also have a serious impact on aircraft. From 1990-2001, 1,029 strikes to civil aircraft involving wildlife other than birds were reported to the Federal Aviation Administration (FAA). Deer (522) and coyotes (115) were the most commonly struck wildlife. Other non-bird species struck included rabbits, woodchucks, turtles, alligators, and iguanas. Whereas 14% of bird strikes resulted in aircraft damage and 9% had a negative effect on the flight, 47% of strikes with other wildlife caused damage and 33% had a negative effect …

Implementation Of Gis Technology To Detect Wildlife Hazards At Airports, Michelle L. Gray Oct 2002

Implementation Of Gis Technology To Detect Wildlife Hazards At Airports, Michelle L. Gray

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Increasing Air Safety At Eglin Air Force Base Through Vulture Roost Dispersal, John S. Humphrey Oct 2002

Increasing Air Safety At Eglin Air Force Base Through Vulture Roost Dispersal, John S. Humphrey

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Compliance With Wildlife Hazard Regulations: An Air Carrier’S Perspective, Vern Berry Oct 2002

Compliance With Wildlife Hazard Regulations: An Air Carrier’S Perspective, Vern Berry

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

As a safety professional at Evergreen International Airlines, I have first-hand experience of the damage caused by wildlife. Seven major bird strikes have cost Evergreen approximately $20 million in damages and lost revenue over a 5-year period. These events often occurred during critical phases of flight. For example, one Evergreen B-747 suffered severe damage to engine and pylon structure with subsequent loss of control during climb. You cannot train for every possible aircraft failure induced by bird strikes. The time will come, with or without the collection of additional bird-strike statistics, when damage from a bird strike will exceed the …

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

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Reported Bird Strikes At Down-State Illinois Airports, Michael W. Rapps Oct 2002

Reported Bird Strikes At Down-State Illinois Airports, Michael W. Rapps

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Influence Of The Bash Phase Ii Program On Reduction Of Birdstrikes To Air Mobility Command Aircraft, Brian D. Oswalt Oct 2002

Influence Of The Bash Phase Ii Program On Reduction Of Birdstrikes To Air Mobility Command Aircraft, Brian D. Oswalt

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

The purpose of the proposed study was to examine the reduction of birdstrikes to aircraft during the Bird Aircraft Strike Hazard (BASH) Phase II flight restriction periods and their affect on Air Mobility Command (AMC) and the U.S. Air Force (USAF). This study sampled the entire population of AMC airfields with BASH Phase II flight restrictions. The test period consisted of damaging birdstrike data collected 5 years before BASH Phase II operations began (1991-1995), and the years during BASH Phase II (1996-2000). It was hypothesized that since the implementation of BASH Phase II flight restrictions, there had been no significant …

Progress Report On Development Of A Terminal Area Bird Detection And Monitoring System Using The Asr-9, Seth Troxel, Beth Echels, Will Pughe, Mark Weber

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Lincoln Laboratory has been tasked by the FAA to investigate utilization of existing terminal area surveillance radars as the basis for a real-time, automated bird hazard advisory system for the immediate airport vicinity. With its on-airport siting and rapid scan rate, the ASR-9 is a logical choice as the primary sensor for the Terminal Avian Hazard Advisory System (TAHAS). Using multi-dimensional image processing and fuzzy logic techniques, a bird-flock detection module that operates on ASR-9 data has been developed and was described at last year's conference. Refinements to the flock detection module are ongoing. Recent efforts have focused on detection …

A Progression Of Avian Radar Studies At Airfields, Edward J. Zakrajsek, Carolyn Matkovich, Andreas Smith

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

We used our Mobile Avian Radar Systems on two different projects this past year. A study at Robins Air Force Base, Georgia, used the old configuration, with a vertical-scanning radar and our image-processing technique. A study at Vancouver International Airport, B.C. used the new configuration with both vertical and surveillance radars and our new radar data processing technique. The Robins study was a preliminary assessment of seasonal bird-hazards, especially regarding the altitude distribution of birds near the airfield. Data was collected. The Vancouver study was a preliminary survey and system evaluation for the development of a real- time, dedicated Airport …

Need For Certification Program For Persons Conducting Wildlife Hazard Management Activities At Airports, John Ostrom Oct 2002

Need For Certification Program For Persons Conducting Wildlife Hazard Management Activities At Airports, John Ostrom

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Even With Good Equipment, Experienced Manpower Is Necessary, Nigel Horton Oct 2002

Even With Good Equipment, Experienced Manpower Is Necessary, Nigel Horton

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

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

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Strides In Bird Hazard Control At Entebbe International Airport, Gloria Korabo Bitebekezi Oct 2002

Strides In Bird Hazard Control At Entebbe International Airport, Gloria Korabo Bitebekezi

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

The location of Entebbe International Airport within the Entebbe peninsula bird sanctuary would make it one of the most bird-strike prone airports in the world. However the airport actually has a relatively clean strike record. Since 1998, the number of bird strike incidents that caused damage to aircraft has been on the decline. This paper illustrates the methods used at Entebbe International Airport and their effectiveness in controlling different species of birds.

Bird Hazard Control Program At Panama Airports, Esteban Godinez

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

ICAO Bird Information System (IBIS) has been conduced at Panama airports since 1996. Bird strike notifications, technical reports as well as wildlife control procedures have been developing as essential roles of the National Bird Hazard Committee and its Wildlife Limitation Programs. Sixty-four (64) bird strikes with different aircraft were recorded and sent to ICAO so far, while an additional 154 collisions (71%) were not reported to ICAO because of the failure to determine the aircraft involved. Among the birds struck at airports, the most outstanding species are the common barn owl (Tyto alba) and the black vulture (Coragyps …

Wildlife Hazard Management In Micronesia: Aviation Safety In Uncharted Territory, Daniel S. Vice Oct 2002

Wildlife Hazard Management In Micronesia: Aviation Safety In Uncharted Territory, Daniel S. Vice

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 Oct 2002

Bird Strikes In Courts: The Genoa Case, Valter Battistoni

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 Oct 2002

Monte-Carlo Simulation Of Birdstrike To Support Rule Making For Large Birds, Julian M. Reed

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

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 …

Potential Of Grass-Endophytes As A Bird Deterrent: Concept Testing With Canada Geese, Chris G. L. Pennell, Phil Rolston Oct 2002

Potential Of Grass-Endophytes As A Bird Deterrent: Concept Testing With Canada Geese, Chris G. L. Pennell, Phil Rolston

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Problems caused by birds in the agricultural, horticultural, recreational and the aviation industries are escalating world wide as man develops environments that are attractive to birds. Chemical repellents, bird scarers, and exclusion netting are being used to keep birds away by taste, fright and containment. Habitat management using grasses with selected endophytes may be a new tool for minimizing bird nuisance problems in these industries. Canada geese (Branta Canadensis) were offered selected ryegrass/endophyte Neotyphodium lolli seed and herbage to examine the effects of known endophyte alkaloids on their feeding behavior in 2000-2001. Forty geese were captured annually, contained …
