Ninety-three percent of all reported bird strikes occur below 1,067 m, which based on the typical approach and departure angles of aircraft is within 8–13 km of an airport. Concomitantly, the Federal Aviation Administration and the International Civil Aviation Organization recommend that any feature that would attract hazardous wildlife to the approach and departure airspace be restricted. Thus, preventing the establishment of wildlife attractants, such as municipal solid waste landfills (MSWLFs) within 8 km or 13 km extents (U.S. and international recommendations, respectively) of airports, has been recommended to mitigate the risk of bird–aircraft collisions (strikes). However, robust evidence linking …
Population Increases Of Large Birds In North America Pose Challenges For Aviation Safety, Richard A. Dolbeer
Population Increases Of Large Birds In North America Pose Challenges For Aviation Safety, Richard A. Dolbeer
USDA Wildlife Services: Staff Publications
There is a strong correlation between bird mass and the likelihood of aircraft damage during a bird–aircraft collision. Thus, the U.S. Federal Aviation Administration (FAA) has established airworthiness standards related to bird mass for engines, airframes, and windshields. Most standards use large (1.8 kg) and medium (1.1 kg) birds as benchmarks (the empennage and certain large turbofan engines use a 3.6-kg bird). There are 20 large (≥1.8 kg) and 16 medium (1.1–1.7 kg) bird species in North America with ≥20 strikes reported for civil aircraft (FAA National Wildlife Strike Database), 1990 to 2018. I analyzed the population changes of these …

The U.S. Federal Aviation Administration's (FAA) National Wildlife Strike Database (NWSD) documents reports of civil aircraft collisions with wildlife in USA. The NWSD has been managed by the Wildlife Services Program of the U.S. Department of Agriculture through an interagency agreement since its inception. Although the NWSD includes about 170,000 reports of civil aircraft collisions with wildlife (97% birds) from 1990-2015 (14,000 in 2015), the overriding focus has been the quality control of data entered for over 90 variables ranging from species and numbers of wildlife struck, location and time of day, phase and height of flight, aircraft type, components …
Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser
Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser

Canada geese (Branta canadensis) often cause significant damage when they strike aircraft. They are responsible for a reported minimum of $2.6 million in damage per year to civil aviation in the United States. Knowledge of goose movements in relation to airports would allow wildlife managers to allocate time and funds to manage those populations that pose the greatest threat to aircraft. We placed alpha-numeric neck collars on 300 Canada geese within 8 km of both John F. Kennedy International Airport (JFKIA) and LaGuardia Airport in New York, New York. We conducted weekly observations for 2 years within a …

USDA Wildlife Services: Staff Publications
From 1990 through 2003, 52,493 wildlife collisions with aircraft were reported to the U.S. Federal Aviation Administration (FAA); 97% of these incidents involved birds. The approximate cost to the civil aviation industry in the U.S.A. due to collisions of birds with aircraft (hereafter referred to as bird strikes) was $163.51 million in direct monetary losses and associated costs for the 14 year period (Cleary et al. 2004). Strikes with raptors (Falconidae and Accipitridae; including vultures, Cathartidae)accounted for approximately 28% of reported aircraft down time resulting from known-species bird strikes (known species =182942 hr; total for all birds = 244510 hr) …
Height Distribution Of Birds Recorded By Collisions With Civil Aircraft, Richard A. Dolbeer
Height Distribution Of Birds Recorded By Collisions With Civil Aircraft, Richard A. Dolbeer
USDA Wildlife Services: Staff Publications
The National Wildlife Strike Database for Civil Aviation in the United States contained 38,961 reports of aircraft collisions with birds (bird strikes) from 1990–2004 in which the report indicated the height above ground level (AGL). I analyzed these strike reports to determine the distribution of all strikes and those strikes causing substantial damage to aircraft by height. For the 26% of strikes above 500 feet (152 m) AGL (n=10,143), a simple negative exponential model, with height as the independent variable, explained 99% of the variation in number of bird strikes per 1,000-foot (305-m) interval. Strikes declined consistently by 32% every …
Blackbird And Starling Strikes To Civil Aircraft In The United States, 1990-2001, Scott C. Barras, Sandra E. Wright, Thomas E. Seamans
Blackbird And Starling Strikes To Civil Aircraft In The United States, 1990-2001, Scott C. Barras, Sandra E. Wright, Thomas E. Seamans

Bird-aircraft collisions (bird strikes) pose hazards to aircraft and cost civil aviation hundreds of millions of dollars in repairs and logistical expenses annually in the United States. Blackbirds and starlings (Sturnus vulgaris) in particular have caused some of the most devastating aircraft accidents related to bird strikes in the United States and Europe. To determine the impacts of blackbirds and starlings to aviation in the United State, we searched the Federal Aviation Administration’s (FAA) National Wildlife Strike Database for all reported strikes involving these species. During 1990-2001, 1,704 strikes involving blackbirds and starlings were reported to the FAA …
Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica W. Fantinato
Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica W. Fantinato
USDA Wildlife Services: Staff Publications
Birds pose serious hazards at U.S. airports because of the potential for collisions with aircraft. Raptors, in particular, are hazardous to aircraft safety due to their size, hunting behavior, and hovering/soaring habits. Reduction of rodent populations at an airport may decrease raptor populations in the area and therefore, reduce the risk that raptors pose to aircraft. Rodent populations can be reduced by population management (i.e., use of rodenticides) or by habitat management (i.e., vegetation management, barriers, and land uses) that reduces the area’s carrying capacity for rodents. We discuss potential approaches to reduce rodent populations at airports within the context …
Have Population Increases Of Large Birds Outpaced Airworthiness Standards For Civil Aircraft?, Richard A. Dolbeer, Paul Eschenfelder
Have Population Increases Of Large Birds Outpaced Airworthiness Standards For Civil Aircraft?, Richard A. Dolbeer, Paul Eschenfelder
USDA Wildlife Services: Staff Publications
Bird-aircraft collisions (bird strikes) are an increasing safety and economic concern to the USA civil aviation industry, costing over $400 million each year. One approach to reducing risks associated with strikes is to require commercial aircraft components to meet certain standards of safe performance in the event of a bird strike. The Federal Aviation Administration has developed airworthiness standards for airframes, windshields and engines using a single 4-lb (1.82-kg) bird mass as the maximum that must be tested (with the exception of a single 8-lb bird for the empennage, 6-lb bird for certain mid-sized engines that may be developed in …
Habitat Management Approaches For Reducing Wildlife Use Of Airfields, Scott C. Barras, Thomas W. Seamans
Habitat Management Approaches For Reducing Wildlife Use Of Airfields, Scott C. Barras, Thomas W. Seamans
USDA Wildlife Services: Staff Publications
Wildlife-aircraft collisions (wildlife strikes) pose safety risks to aircraft and cost civil aviation over $390 million annually in the USA We reviewed published studies to summarize findings on habitat management techniques that have shown potential for wildlife strike reduction. Habitat components that may attract wildlife to airports include food, cover, water, and loafing areas. Although maintaining tall herbaceous vegetation on airfields may reduce the attractiveness of loafing and feeding sites for some species of birds such as gulls, this strategy may also increase cover and food resources for other hazardous species. Thus, optimum vegetation height management strategies require further research …

Bird strikes to aircraft are a globally pervasive safety and economic concern. In particular, the Anchorage, Alaska area holds substantial risk for destructive collisions between birds and aircraft. An international airport, a municipal airport, a seaplane base, and a U.S. Air Force base are situated throughout the area. Anchorage also has a burgeoning population of Canada geese (Branta canadensis parvipes), one of the species identified as posing the greatest airstrike hazards. A variety of methods are applied and a variety of research has been conducted to reduce the potential for airstrikes with geese around Anchorage.We review the nature …
