The Use Of Radar To Augment Visual Observations In Wildlife Hazard Assesments, Robert C. Beason, Michael J. Begier
The Use Of Radar To Augment Visual Observations In Wildlife Hazard Assesments, Robert C. Beason, Michael J. Begier
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
The Airport Is Not A Wildlife Refuge!, Russell P. Defusco, Robert L. Dogan
The Airport Is Not A Wildlife Refuge!, Russell P. Defusco, Robert L. Dogan
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Airport Canopies Become Starling Roosts – Two Airport Case Studies, Sharon Gordon, Randolph J. White
Airport Canopies Become Starling Roosts – Two Airport Case Studies, Sharon Gordon, Randolph J. White
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …

Evaluation Of Bird-Strike Risk In Two Colombian Airports: A Standard Methodology To Rank Species And Propose Management Priorities, Juan David Amaya-Espinel, Sergio Córdoba-Córdoba, Guillermo Rico-Hernández
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
We conducted avian evaluations at two Colombian airports to assess, through a standard methodology, the risk of bird strikes. Evaluations were conducted at “Aeropuerto Perales” (AP), Department of Tolima, 1030 m a.s.l. Tropical Dry Forest and, “Aeropuerto Palonegro” (APN), Department of Santander, 1188 m a.s.l. Humid Pre-mountain Forest. Forty-seven species of 12 different families, 3,998 individuals were encountered at AP through 1284 records. In contrast, 33 species of 16 families, 1,112 individuals in 396 records were found at APN. The Whispering ibis (Phimosus infuscatus) was the most abundant species with more than 50% of all individuals followed by the Black …

Real Birds Versus Whirly Birds: Bird Strikes To Civil Helicopters In The Usa, 1990-2005, Richard A. Dolbeer, Sandra E. Wright, Edward C. Cleary
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
To our knowledge, there has been no published analysis of bird strike data specific to helicopters. Our objective was to conduct a comparative analysis of strike reports involving helicopters and fixed-wing aircraft from the Federal Aviation Administration’s Wildlife Strike Database. From 1990-2005, 370 (0.6%) of the 64,734 reported bird strikes to civil aircraft involved helicopters. Of the 370 reported bird strikes involving helicopters, 186 (50%) indicated damage and 67 (18%) indicated substantial damage. In contrast, only 15% of bird strikes with fixed-wing aircraft resulted in damage and 4% resulted in substantial damage. Whereas helicopters accounted for only 0.6% of all …
Dna Identification Of Bird Strike Remains – Procedures And Technical Considerations., Nancy Rotzel
Dna Identification Of Bird Strike Remains – Procedures And Technical Considerations., Nancy Rotzel
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
This poster presents the development of DNA techniques by the Smithsonian Institution Feather Lab to identify bird remains recovered from military and civil bird aircraft collisions (bird strikes). The following steps for molecular identification of forensic samples are explained: receipt of sample, extraction, amplification, sequencing, and final data analysis using computer software. Recommendations for collecting bird strike samples for DNA analysis are also discussed. This work compliments the continuing work of the Feather Lab by providing a molecular signature to verify bird strike samples that do not contain sufficient feather remains for morphological identification.
Remote Sensing Technology And Ground-Based Observations For Evaluating A Proposed Airport Site In Conway, Arkansas, Russell P. Defusco, Ronald L. Merritt
Remote Sensing Technology And Ground-Based Observations For Evaluating A Proposed Airport Site In Conway, Arkansas, Russell P. Defusco, Ronald L. Merritt
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
The city of Conway Arkansas has proposed a replacement for its existing airport with a larger, more modern facility. Site selection and architectural design began eleven years ago with a preferred location selected near the Arkansas River. After nearly completing the architectural plans for construction, preliminary approval was granted from the FAA regional office pending final coordination from their headquarters. The FAA asked their Staff Wildlife Biologist to evaluate and endorse the proposed location. Concerns over local land uses and the proximity to a potential major flyway led the FAA to withhold support for the site pending further study. The …
Disposal Of Bio-Solids At Airports: Increased Wildlife Hazards To Aviation Or Not?, Michael J. Begier, Brian E. Washburn
Disposal Of Bio-Solids At Airports: Increased Wildlife Hazards To Aviation Or Not?, Michael J. Begier, Brian E. Washburn
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Response Of Birds To Aircraft Lighting: Implications For Reducing Bird-Aircraft Collisions, Bradley F. Blackwell, Thomas W. Seamans, Scott Philiben
Response Of Birds To Aircraft Lighting: Implications For Reducing Bird-Aircraft Collisions, Bradley F. Blackwell, Thomas W. Seamans, Scott Philiben
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Birds Commuting Across The Runway: How To Reduce This Bird Strike Risk?, Albert De Hoon, Luit Buurma
Birds Commuting Across The Runway: How To Reduce This Bird Strike Risk?, Albert De Hoon, Luit Buurma
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Media Response Plans – The Forgotten Tools, John E. Ostrom
Media Response Plans – The Forgotten Tools, John E. Ostrom
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
The Media Response Plan is an essential tool for any wildlife management program’s toolbox, and yet, is normally not thought about until after something unpleasant happens and the media are knocking at your door. Developing an effective Media Response Plan is critical to the success of your wildlife management program and provides any manager with the opportunity to be prepared for both proactive and reactive situations when dealing with the media.
Canada Goose Populations And Strikes With Civil Aircraft: Positive Trends For Aviation Industry, Richard A. Dolbeer, John L. Seubert
Canada Goose Populations And Strikes With Civil Aircraft: Positive Trends For Aviation Industry, Richard A. Dolbeer, John L. Seubert
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Developing A Risk Rating System For Bird Strike Occurrences, Albert Froneman
Developing A Risk Rating System For Bird Strike Occurrences, Albert Froneman
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Bird strike reporting is becoming increasingly important as airport operators, airlines and government aviation authorities are requesting their staff to report all bird strike occurrences. In South Africa the Endangered Wildlife Trust has been managing an integrated bird and wildlife hazard management program at ten airports managed by the Airports Company South Africa for the past seven years. In an attempt to best understand the bird strike hazard at the various airports a bird strike definition has been adopted which includes the reporting of carcass remain retrieved from the runways through to the more serious incidents where damage was reported …

Bird Classification In Noisy Environments: Theory, Results And Comparative Studies, Y. Zhang, C. Kwan, D. Lao, Y. Deng
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Bird classification plays an important role in minimizing collisions between birds and aircraft. It is a challenging task to perform the sound-based classification correctly in a noisy environment. This paper addresses robust techniques that can improve the classification of bird in noisy environments. A complete recognition system is described and evaluated on a bird sound database containing 1547 bird sound files, with 11 bird species. Two types of features were extracted from the sound files: Mel Frequency Cepstral Coefficient (Mfcc) and RelAtive SpecTrAl (RASTA). Also, two statistical classifiers were developed using Gaussian Mixture Models (GMM) and Hidden Markov Models (HMM), …

Reduction Of Risk: A Flight Crew Guide To The Avoidance And Mitigation Of Wildlife Strikes To Aircraft, Paul Eschenfelder, Steve Hull
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
International Birdstrike Committee Minimum Best Practice Standards For Aerodrome Bird Control, John R. Allan
International Birdstrike Committee Minimum Best Practice Standards For Aerodrome Bird Control, John R. Allan
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Despite almost 40 years of research effort and operational experience, there remains very limited consensus concerning the best methods for managing the bird strike hazard at aerodromes. This is, in part, because the levels of risk, habitat type and bird species present at different aerodromes varies and the precise techniques that are successful at one site may not work at another. It is also partly due to differences in the levels of resources available at different airports and to differences in the attitude of airport managers and national regulators to the hazard posed by bird strikes. Following the implementation of …
Remote Sensing Of Birds Around Airports – Present Efforts In Germany, Wilhelm Ruhe, Reinhold Hill
Remote Sensing Of Birds Around Airports – Present Efforts In Germany, Wilhelm Ruhe, Reinhold Hill
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
As birds around airports and military airfields are a potential danger for air traffic, there are ongoing efforts, also in Germany, to monitor birds in conflicting airspaces. Besides other factors the spatial scale very much determines system demands and the resolution of detections. Based on the well known time lapse photography technique, digital video recording of radar screens is still used in long term (e.g. 2 years) bird monitoring studies at German airports. The technical equipment is easily installed and the remote controlled systems are working very reliable. However, data analysis is time consuming and needs a good deal of …

Developing Protocols For Bird Strike Radar Performance Assessment, Edwin E. Herricks
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Over the past six years the Center of Excellence in Airport Technology (CEAT) has been supporting Federal Aviation Administration research in aircraft and airport safety. CEAT has conducted reviews of bird strike sensor technology, and has led validation testing of a radar developed specifically for bird detection at airports. This experience, which includes development of quality assurance plans and field validation of radar capabilities has led to the development of protocols for bird strike radar performance assessment. The protocols to be reviewed are based on a request made to bird radar vendors that asked for information in three areas: 1) …

Lessons Learnt From Avian Radar Trial At Toronto Pearson International Airport, Tim J. Nohara
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
The paper reports on lessons learnt from an avian radar trial conducted at Toronto Pearson International Airport in November 2005. Toronto Pearson International Airport is Canada's largest airport and has unique requirements due to its proximity to metropolitan Toronto, a major urban center. The paper begins with an assessment of desirable application requirements that take into account current wildlife management practices. Application requirements include early warning of birds approaching the airfield; real-time tracking of birds and aircraft, rapid review of overnight bird movements to identify bird stopovers, and integration into wildlife management operations. Next, the paper examines special radar design …

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
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Potential Wildlife Control Through Use Of A Plant Growth Regulator, Thomas W. Seamans, Brian E. Washburn
Potential Wildlife Control Through Use Of A Plant Growth Regulator, Thomas W. Seamans, Brian E. Washburn
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Habitat management techniques that reduce wildlife use of habitats on and around airports are critical for safe airport operations. Herbaceous vegetation comprises the main habitat type at airports and vegetation can be managed by various methods. The objective of this study was to compare bird and mammal use of grassland habitat managed either by mechanical (mowing) or chemical (plant growth regulator) methods. We monitored vegetation growth, plant community composition, and wildlife activity each week during May – October 2003 in study plots located in Erie County, Ohio. Vegetation was taller (P < 0.01) and denser (P < 0.01) in unmanaged plots than in managed (mowed or growth regulator) plots. Plots sprayed with growth regulator had lower forb/legume cover and higher grass cover than unmanaged or mowed plots. We observed more (P < 0.001) birds (× ± SE) per 5-minute survey on the ground in or perched on vegetation in unmanaged (3.0 ± 0.3) than mowed (1.5 ± 0.2) or growth regulator (1.5 ± 0.3) plots. More (P < 0.001) white-tailed deer were observed in mowed plots (4.3 ± 0.5) than either unmanaged (2.2 ± 0.6) or growth regulator (1.6 ± 0.3) plots. Fifteen small animals were captured in control plots, whereas no animals were captured in managed plots. Applying plant growth regulator did not maintain desired vegetation height and thus is not a costeffective alternative to mowing in plant communities of mixed composition. Managing vegetation height reduced wildlife use of grassland habitats. Removal of forbs and legumes by the growth regulator might explain the reduction in deer use in these plots. Reducing forbs and legumes might also make grasslands less attractive to small mammals. By simplifying herbaceous communities and encouraging plants less desirable to wildlife, it may be possible to reduce the attractiveness of airfields to wildlife species hazardous to aviation.
Cattle Grazing As Part Of An Integrated Management Program To Reduce Wildlife Hazards At Kansas City International Airport, Dan Mcmurtry
Cattle Grazing As Part Of An Integrated Management Program To Reduce Wildlife Hazards At Kansas City International Airport, Dan Mcmurtry
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Opening in 1972, the Kansas City International Airport (MCI) has had numerous issues concerning white-tailed deer. The first documented deer strikes at MCI were in 1979 and 1980. Between 1996 and 2000, airport operations entered 39 reports of deer inside the fence on the AOA, or 0.72 deer incursions per month, and 28 instances where deer were struck by vehicles on airport property. In one situation, a deer entered the airport terminal by breaking through a large glass window and injured three people. After a Wildlife Hazard Assessment was completed in 1997, Wildlife Services and MCI worked together closely to …
Prey Manipulation As A Management Strategy At An Inland South African Airport, Ordino Kok
Prey Manipulation As A Management Strategy At An Inland South African Airport, Ordino Kok
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
Bird Use Of Stormwater Management Ponds: Design Considerations Relative To Decreasing Strikes With Aircraft, Bradley F. Blackwell, Laurence M. Schafer
Bird Use Of Stormwater Management Ponds: Design Considerations Relative To Decreasing Strikes With Aircraft, Bradley F. Blackwell, Laurence M. Schafer
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Airports must control the movement of storm water away from runways, taxiways, and aprons to insure the safety of aircraft operations. The U.S. Federal Aviation Administration recommends that such runoff be held for short periods, by use of detention ponds, so as to reduce use by wildlife (Advisory Circular No: 150/5200-33A; Hazardous Wildlife Attractants On or Near Airports). The purpose of our study was to quantify factors that potentially attract avian wildlife to stormwater management ponds so as to more efficiently direct resources toward management of hazards to aviation posed by these habitats, and provide critical input on the design …
The Impacts Of Habitat Manipulation On The Ring-Necked Pheasant Population At Cck Air Force Base In Taiwan, Shaopin Yo, Kuo-Bin Lin
The Impacts Of Habitat Manipulation On The Ring-Necked Pheasant Population At Cck Air Force Base In Taiwan, Shaopin Yo, Kuo-Bin Lin
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
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 …
The Effect Of Harassment By Dogs On Ground-Nesting Birds In Airfields, Shlomi Brandwine, Nicholas B. Carter
The Effect Of Harassment By Dogs On Ground-Nesting Birds In Airfields, Shlomi Brandwine, Nicholas B. Carter
2006 Bird Strike Committee USA/Canada, 8th Annual Meeting, St. Louis, MO
Ground-nesting birds like lapwings and sandpipers constitute a major hazard at airports. Preliminary observations with the Israeli Air Force showed that stone curlew (Burhinusoedicnemus, (Burhinidea)) were involved in 33% of all bird strikes in 2003 at Hatzor Air Force base in central Israel, most of which occurred during the nesting season. The ultimate reduction of curlew populations near the runways is dependent upon understanding the effect of predation risks on the curlew nesting behavior. In theory, true predation and artificial predation should have the same effect on bird behavior. We studied the effect of egg collection vs. egg collection complemented …
