Strategies For Mitigating Bird Strike Risk From Vulture Populations At Macdill Afb, John Gilbert, Karen Voltura Aug 2008

Strategies For Mitigating Bird Strike Risk From Vulture Populations At Macdill Afb, John Gilbert, Karen Voltura

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Over the last 20 years, strikes with vultures have accounted for 1/3 of the total damage to aircraft at MacDill AFB in Tampa, FL. Locally, vulture populations increase in the fall as flocks migrate south and winter in the Tampa Bay area. Aerial surveys as well as ground surveys were used to identify vulture roost locations and data on daily movement patterns were collected. Black and Turkey vultures were roosting within one-half mile of the runway in adjacent mangroves and on nearby large fuel tanks for two oil distributors for the Port of Tampa. The vultures caused frequent increases in …

Assessing Movement, Site Preferences, And Environmental And Social Impacts Of Canada Geese Across An Urban Landscape, M. Elizabeth Rutledge, Christopher Deperno, Christopher Moorman, Michael Begier, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Resident Canada goose (Branta canadensis maxima) populations have increased, causing many human-goose conflicts. These include decreased water quality, aggressive behavior towards humans and pets, the risk of disease from fecal contamination, and the potential for bird strikes to aircraft. To better understand these human-goose conflicts and potential risk to airport safety, we will examine Canada geese movements, habitat use, human attitudes toward geese, and disease transmission on the Piedmont-Triad International airport and surrounding areas of Greensboro, North Carolina. We will use a variety of tools, such as color-marking with auxiliary neck bands, satellite telemetry with global positioning system …

Storm-Water Retention, Grain Production, And Aviation In The Southern Great Plains, Philip Robinson, Alicia Bernard, Bradley F. Blackwell

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

How might grain-crop agriculture and stormwater-retention structures within FAA airport sighting criteria affect bird strike risk? We summarize over seven months of data (20 August 2007–31 March 2008) from an on-going wildlife hazard assessment at a General Aviation airport in north central Oklahoma, including concurrent observations at 10 stormwater-retention structures within the two-mile sighting criteria. The landscape within the 5-mile FAA sighting criteria is a mix of rural and suburban areas, but includes approximately 75% agriculture, 1,339 water bodies (315 km of shoreline) composing 617 ha of water held predominantly in private and municipal stormwater-retention structures. We conducted weekly, systematic …

Deployment And Assessment Of Avian Radars, Edwin Herricks, Elizabeth Woodworth, Ryan King

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

As part of a multiple year Federal Aviation Administration research program in Airport Safety (AAR-411), avian radar units have been deployed at Seattle- Tacoma International Airport (SEA) and the Naval Air Station Whidbey Island, Oak Harbor, Washington (NASWI) by the University of Illinois Center of Excellence in Airport Technology (CEAT). The radars have been operating for a year or more providing performance data and information on bird movement dynamics. The CEAT performance assessment program has been comprehensive considering sensor location, radar calibration, data acquisition and management, and data visualization. Sensor location issues are associated with antenna type, ambient clutter, and …


Vulture Management At Avon Park Air Force Range, Florida, John S. Humphrey, Michael L. Avery, Michael Milleson, Troy Hershberger Aug 2008

Vulture Management At Avon Park Air Force Range, Florida, John S. Humphrey, Michael L. Avery, Michael Milleson, Troy Hershberger

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Coincident with rising vulture populations have been reports of increased aircraft safety issues. There have been over 700 vulture strikes with US Air Force aircraft at costs in excess of $150 million. The Avon Park Air Force Range (APAFR) harbors a thriving vulture population which often creates dangerous situations for pilots on low-level training missions. In 2005-2006, we conducted research to 1) disperse vultures from roosts on and near the APAFR; 2) assess vulture use of the ranges before and after roost dispersal; and 3) evaluate vulture use of the surrounding area. Baseline counts of vultures leaving a large nearby …


A Decade Of United States Air Force Bat Strikes, Suzanne Peurach, Carla Dove, Laura Stepko Aug 2008

A Decade Of United States Air Force Bat Strikes, Suzanne Peurach, Carla Dove, Laura Stepko

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

From 1997 to 2007, 821 bat strikes were reported to the United States Air Force (USAF). Many samples were identified by macroscopic and/or microscopic comparisons with bat specimens housed in the Smithsonian’s National Museum of Natural History, and in recent years by using molecular techniques. We received bat strike reports from 20 countries and 40 of the United States during this time frame. Forty-six percent of the strikes were identified to order; 5% were identified to family or genus; and 49% were identified to the species level. Fiftyfive of the 101 bat strikes submitted for DNA analysis since 2006 resulted …


Would You Please Move? Translocation Of Immature Bald Eagles To Reduce Bird Strike Risk, Alan Schumacher, Brian Washburn, John P. Hart Aug 2008

Would You Please Move? Translocation Of Immature Bald Eagles To Reduce Bird Strike Risk, Alan Schumacher, Brian Washburn, John P. Hart

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Though once endangered, bald eagle populations in the lower 48 States has increased considerably in recent years. Bald eagles far exceed the airworthiness standards for airframes, windshields, and engines set by the Federal Aviation Administration (FAA); consequently this species poses a high risk of damage to aircraft and passenger safety when eagle-aircraft collisions occur. Given the exponential growth of bald eagle populations in the United States, the risk of bald eagle-aircraft collisions is an increasing problem for airports. Concurrently, there is widespread public interest in eagles with a strong concern that eagle populations be protected. Effective, publically accepted methods to …


Reducing Bird Strike Risks Through Insect Management At A Military Base, Dedrick Pesek, Michael J. Bodenchuck, David J. Hayes, Mark Mapston Aug 2008

Reducing Bird Strike Risks Through Insect Management At A Military Base, Dedrick Pesek, Michael J. Bodenchuck, David J. Hayes, Mark Mapston

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

USDA-APHIS-Wildlife Services (WS) and the U.S. Air Force (USAF) work collaboratively to minimize bird strike risks at Air Force Bases (AFB) nationwide. At Laughlin AFB near Del Rio, Texas migratory, insectivorous birds in the aircraft operations area pose a bird strike risk to pilots and crews. The peak of bird strikes at Laughlin AFB is associated with the peaks of bird migration in the spring and fall. Noting this, WS recommended the application of carbaryl insecticide in the Laughlin AFB operational area to reduce insects and foraging opportunities for birds to reduce bird strike risks. Two trial treatments were conducted …


The Use Of An Integrated Geographical Information System At South African Airports, Claire Patterson-Abrolat Aug 2008

The Use Of An Integrated Geographical Information System At South African Airports, Claire Patterson-Abrolat

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

The use of Geographic Information Systems (GIS) has, over the past few years, become an integral component of the operations at all airports owned and/or operated by the Airports Company South Africa (ACSA). What has however been lacking, is the application of this technology to practically manage and reduce risks out on the airfield. ACSA Bird and Wildlife Management has recently initiated a programme to utilize GIS and global positioning systems (GPS) on their airfields and all ACSA Wildlife Control Officers (WCOs) are now using handheld mobile computers with integrated GPS to record information and track their patrols out on …


Test Of An Alternative Rodent Control Method: Chf Fertilizer/Small Mammal Repellant, Randy J. Outward, Rebecca Mihalco, Thomas W. Seamans Aug 2008

Test Of An Alternative Rodent Control Method: Chf Fertilizer/Small Mammal Repellant, Randy J. Outward, Rebecca Mihalco, Thomas W. Seamans

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Small mammals, primarily rodents, are an indirect threat to aviation safety because they are the prey base for numerous species of raptors. An abundant rodent population at an airport can attract and sustain a significant number of hazardous raptors in the airport vicinity. The use of chemical rodenticides has been shown to reduce rodent populations but may not be practical because of environmental concerns, thus alternative methods are needed. A test of a small mammal repellant, CHF, was conducted at Burke Lakefront Airport in Cleveland, OH. CHF, manufactured by Coolworks BV, is a pelleted, composted 1:1 mixture of mink/fox manure …

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

With the June 2006 release of FAA Advisory Circular 150-5200-36 Qualifications for Wildlife Biologists, a minimum wildlife hazard management curriculum was established for the initial and recurrent training of airport personnel involved in implementing a FAA approved Wildlife Hazard Management Plan. This presentation will show some of the existing programs and “best training” practices from airports across the country along with some future programs. Information offered in this presentation will provide airports and personnel involved in training, ideas on how to better develop and deliver their wildlife management training programs.


Teamwork By Regions In Large Countries Like Brazil — A Good Solution For Bird Strikes, Major Raul Moreira Neto Aug 2008

Teamwork By Regions In Large Countries Like Brazil — A Good Solution For Bird Strikes, Major Raul Moreira Neto

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Since Brazil is a large country, associated to a small number of people working in bird strikes prevention, it was decided to create regional groups, composed by public administrators, Air Force Officers, teachers from universities, professionals from Civil Aviation Agency, airport managers, Justice representatives (prosecutors), and any one that could help us in our tasks. After establishing the group, some researches were made to determine the factors that were attracting birds in the chose airport area, and a schedule of tasks that should be done by each member of the group was created, with deadlines that could be in short, …


Developing Strategies For Long-Term Removal Of Raptors From Airports In California, Todd J. Pitlik Aug 2008

Developing Strategies For Long-Term Removal Of Raptors From Airports In California, Todd J. Pitlik

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Airports in southern California have experienced a number of damaging bird strikes associated with raptors during the last 10 years, including two substantially damaging strikes involving red-tailed hawks. Southern California airfield habitats attract a large variety of small birds and rodents, especially California ground squirrels and pocket gophers, which attract red-tailed hawks and other predators into aircraft movement areas. Effective, publically acceptable methods to reduce prey populations and/or reduce raptor use of airport habitats are needed. Over a 14-month period during 2006-2007, body grip traps and gas cartridges were used to remove 927 California ground squirrels from one airfield. Monthly …


Establishment Of Tall Fescue Cultivars On The Marine Corps Air Station Cherry Point Airfield, Keri Yankus, Michael Begier, Brian E. Washburn Aug 2008

Establishment Of Tall Fescue Cultivars On The Marine Corps Air Station Cherry Point Airfield, Keri Yankus, Michael Begier, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Wildlife-aircraft collisions (wildlife strikes) cause serious safety hazards to aircraft and their occupants. Habitat management is an important component of an integrated approach for reducing wildlife use of airports. Species composition of airfield plant communities influences the degree of attractiveness to wildlife. Recent research has shown that grazing Canada geese do not consume endophyte-infected tall fescue, suggesting endophyte-infected tall fescues (Festuca arundinacea) might be favorable turfgrass varieties to use in reseeding and vegetation renovation projects on airfields. As part of a larger study, we conducted an experiment to determine if selected turf-type tall fescue cultivars would establish on …


Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Sandra Wright, Richard Dolbeer Aug 2008

Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Sandra Wright, Richard Dolbeer

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

The National Wildlife Strike Database for Civil Aviation in the USA became operational in 1995 with the initiation of data entry of all strike reports beginning in 1990. The database contains 82,057 reported strikes from 1990-2007 involving civil aircraft in the USA or USA carriers in foreign countries. About 9,800 of these strike reports have noted damage to the aircraft of which 2,700 indicated the damage was substantial. The database has proven to be a useful source of objective information on the extent and nature of wildlife strikes for personnel at individual airports and for researchers and regulatory agencies at …


Managing Red-Tailed Hawk Perching Sites On Federal Aviation Administration (Faa) Equipment At General Mitchell International Airport (Mke), Milwaukee, Wi, Henri Woods Aug 2008

Managing Red-Tailed Hawk Perching Sites On Federal Aviation Administration (Faa) Equipment At General Mitchell International Airport (Mke), Milwaukee, Wi, Henri Woods

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

General Mitchell International Airport (MKE) located in Milwaukee, WI, has many man-made perching sites used by hawks. Several of these sites need to be addressed to improve air operations safety because of the preference by redtailed hawks. The first perching sites addressed at MKE were six lamp posts at the base of the 128th Air Refueling Wing of the Wisconsin Air National Guard, which were used daily by red-tailed hawks. In order to mitigate the perching, umbrella skeletons (Daddi Long Legs™ or Bird Spider™) were recommended to be attached to the top of each lamp post. After installation of the …


Rapid Dispersal And Long Term Effect On Resident Canada Geese By On-Demand Use Alarm And Alert Call Playback Reinforced With Cracker/Banger Shells, Philip Whitford Aug 2008

Rapid Dispersal And Long Term Effect On Resident Canada Geese By On-Demand Use Alarm And Alert Call Playback Reinforced With Cracker/Banger Shells, Philip Whitford

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Increasing resident Canada geese create major crop loss problems, and increased air strike potential. There is a growing need for effective, non-lethal means to disperse resident Canada geese. Success in removing geese rapidly from any of the above situations should produce results that can be applied to all. From 16 May – 28 August, 2007, alarm/alert call playback from GOOSEBUSTER™ call units, Bird–X Inc., Chicago IL, was used with a one minute delayed reinforcement by firing cracker shells to assess efficacy at reducing goose numbers at a sewage treatment plant and several farms with past records of heavy summer crop …


Assessing Bird-Aircraft Strike Hazard (Bash) Risk Associated With Breeding And Migrating Osprey, Brian E. Washburn, Thomas Olexa, Brian Dorr Aug 2008

Assessing Bird-Aircraft Strike Hazard (Bash) Risk Associated With Breeding And Migrating Osprey, Brian E. Washburn, Thomas Olexa, Brian Dorr

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

The osprey (Pandion haliaetus) is one of the most widely distributed and well studied bird species of the Northern Hemisphere; however, little is known about their potential impacts to military flight operations. A Department of Defense, Legacy Natural Resources Program-funded multi-agency research project examining the strike-risk posed by breeding and migrating Osprey was initiated in 2006. During the 2006 and 2007 nesting seasons, a total of 13 adult Osprey were live-captured, fitted with GPS-capable satellite transmitters, and released from selected nest locations near Langley Air Force Base, Virginia, in the Mid- Atlantic Chesapeake Bay Region. We monitored satellite-tagged …


Green Roofs In The Airport Environment: Pleasant Dreams Or Nightmares?, Ryan M. Swearingin, Craig Pullins, Travis Guerrant, Brian E. Washburn Aug 2008

Green Roofs In The Airport Environment: Pleasant Dreams Or Nightmares?, Ryan M. Swearingin, Craig Pullins, Travis Guerrant, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Green roofs on buildings are becoming very popular in urban areas of the United States. Public benefits of green roof projects include stormwater runoff reduction, improved water quality, reduced urban heat island effects, and aesthetic values. Several green roofs have been constructed in downtown Chicago and large-scale green roofs are currently being planned and implemented at O’Hare International Airport (ORD). Similar to any airport landscaping, green roofs on buildings in the airport environment might attract wildlife hazardous to aviation and could increase the risk of bird-aircraft collisions. No information currently exists in regard to this potential problem. During 2007–2008, we …


A Practical And Cost Effective Approach To Airport Wildlife Management In The Context Of Local Landuse: Two Australian Case Studies, Phil Shaw Aug 2008

A Practical And Cost Effective Approach To Airport Wildlife Management In The Context Of Local Landuse: Two Australian Case Studies, Phil Shaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

The average strike rates at Australian airports are 4.5, 6 and 0.9 per 10,000 movements for different category airports. These rates reflect the diversity and density of Australian avifauna as well as the littoral distribution of most of our major airports. In the past, isolated and piecemeal management approaches such as fixed position scare devices and dispersal by poorly trained and equipped patrols were ineffective at managing strike risk. Here we describe a practical, cost effective and integrated approach that commences with audit, habitat review and field surveys and is followed by risk assessment and mitigation strategies that are reviewed …


As The Worm Turns: Investigations Into Earthworm Control On Airports, Thomas W. Seamans, Glen E. Bernhardt, David Steyer Aug 2008

As The Worm Turns: Investigations Into Earthworm Control On Airports, Thomas W. Seamans, Glen E. Bernhardt, David Steyer

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Earthworms, though generally considered beneficial for soil conditioning, can become a hazard at airports. When found in large numbers on runways or taxiways after heavy rainfall, they create slippery conditions for aircraft rolling over them. Additionally, earthworms attract birds, especially gulls, thereby increasing the risk of bird strikes to aircraft that are landing or taking off. For example, during a 35-minute period on 3 September 2004 at Calgary International Airport (YYC), a B737 of Westjet and an A319 of Air Canada aborted takeoffs after multiple strikes with gulls attracted to the runways to feed on earthworms. The B737 had strikes …


Training Airport Personnel For Wildlife Hazards: Organization, Obligation And Expectation, John Weller Aug 2008

Training Airport Personnel For Wildlife Hazards: Organization, Obligation And Expectation, John Weller

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

It is estimated that the recorded civil wildlife/ aircraft strikes (73,526) from 1990- 2006 represent <20% of their true occurrence and that the cost incurred by the US civil aviation industry exceeds $600 million annually. Twenty-eight percent (16,142) of identifiable strikes that occurred during this time (58,060) were documented by airport personnel and 73% of all reported strikes occurred at or below 500 feet (i.e., typically within the airport environment). It should follow that properly trained airport personnel could make a difference. To reduce aviation/ wildlife conflicts, these personnel attend training seminars to better understand a diversity of subjects such as wildlife threats, mitigation techniques, documentation procedures and regulations. Although the FAA has standardized the basic information to be provided within this training (Advisory Circular No: 150/ 5200-36), its content should be considered malleable from region to region and year to year. In FY-2006, USDA Wildlife Services personnel assisted 674 civilian and military facilities (civilian = 502; military/ civilian joint = 101; military = 71). Wildlife Services provided both operational and technical assistance to 271 and 403 airports respectively; resulting in 1,739 trained personnel from 217 civilian and military airports. During 2006 the WS North Carolina Program implemented an extensive, hands-on training program to assist military, General Aviation and 139 certificated airports to better understand wildlife hazards to aviation and meet FAA Advisory Circular 150/ 5200-36 requirements. Two hundred airport personnel were trained in North Carolina using nationally developed training modules. Because an airports personnel and wildlife concerns are dynamic, training techniques and content should be constantly evaluated and modified. Updated training seminars and modules should be made readily available to all instructors while techniques to quantify the impact of this training should be considered.

Bird Strike Risk Management – A Uk Caa Perspective, Nick Yearwood Jul 2008

Bird Strike Risk Management – A Uk Caa Perspective, Nick Yearwood

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Mandatory bird strike reporting was introduced in the UK in January 2004, resulting in a 60% increase in reporting. Although reporting is mandated for aircrew only, currently the CAA has no procedure for ensuring compliance. Approximately 2,000 bird strikes are reported annually to the UK CAA (a 3 fold increase since 1990), of which approximately 1,400 are considered ‘confirmed’ strikes. Serious strike events, i.e. those causing damage or having an effect on flight, account for 55-60 occurrences per annum; this number has not increased in line with the increase in traffic levels, 2000-2007. The CAA, working with aviation stakeholders, published …


Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth Jul 2008

Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth

Curriculum materials (FE)

In the “Alien Invaders!” program, students use the Forever Earth vessel to investigate how quagga mussels might affect Lake Mead. Students collect water quality data such as clarity, pH, and temperature to determine whether current habitat conditions would allow quagga mussels to survive and thrive. Students learn about the consequences the quagga mussels could have on the lake and its living and non-living resources. Using the knowledge they’ve gained, students create their own management plans to prevent the spread of quagga mussels to other waterways.

This activity involves students in the concepts of introduced and invasive species
