Does Tall Grass Reduce Bird Numbers On Airports?: Results Of Pen Test With Canada Geese And Field Trials At Two Airports, 1998, Thomas W. Seamans, Richard A. Dolbeer, Mark S. Carrara, Richard B. Chipman

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

A suggested management plan to reduce bird numbers and bird-aircraft collisions at airports is to maintain grass 15-25 cm high. However, 3 studies conducted in the United States in 1998 indicated tall-grass management may not result in fewer birds. First, Canada geese (Branta canadensis), in a replicated experiment lasting 9 days in 6 pens in Ohio, showed no preference (P = 0.53) for short-grass (4-11 cm) over tall-grass (16-21 cm) plots. Second, we compared bird use of 8 tall- (23.3 ± 0.5 cm high, x ± SE) and 8 short- (14.3 ± 0.2) grass plots totaling 46 ha at Burke …

The German Military Geophysical Service. Bird Migration Observation, Warning And Forecasting System: New Developments Towards An Automated Bird Migration Information System, Wilhelm Ruhe

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The German Military Geophysical Office (GMGO) has a more than 30-years experience in all fields of bird strike prevention. Military training and flight operations usually take place in low altitudes, where also a lot of birds are present, especially near coasts and during migration periods. About one third of all the GAF bird strikes occurs during low level flight operations. The most effective tool for bird strike prevention in military low level flying is the well proved system of
· continuous actual bird migration observation (visual and by radar),
· immediate reporting,
· centralised risk evaluation,
· online warning (BIRDTAM), …

Integrated Management Systems For Australian White Ibis (Threskiornis Molucca) On The Gold Coast, Queensland, Australia, Phillip P. Shaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fueled by a large supplemental food supply at landfills in South-east Queensland, Australian White Ibis (Threskiornis molucca) populations grew from an estimated 5000 to 10000 between 1995 and 1998. Ibis counted at Coolangatta Airport reflected this growth with a 556% increase between 1989 and 1995. The multimillion-dollar loss of a Qantas airbus engine from ingestion of an Ibis, resulted in the establishment of the Ibis Management Coordination Group (IMCG). This group, comprising government, industry and community representatives, instigated an integrated program of food reduction, restriction of breeding success and public education. The program has become an example for management programs …

Raising Public Awareness Of Bird Strike Risk Issues With An Enhanced Bird Strike Committee Usa Web Site, Todd Curtis

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Since 1997, a World Wide Web site managed by a member of Bird Strike Committee USA and a site managed by the Committee leadership were instrumental in supporting Committee efforts to reduce these hazards. Based on insights gained from these two Web sites, a new site was created that contained the most effective elements of the earlier sites and new elements designed to enhance the ability of the Committee to accomplish its mission. The new elements included the acquisition and use of the domain name birdstrike.org, the ability to electronically submit bird and other wildlife strike reports directly into the …

Coping Strategies For The Aircraft Birdstrike Problem: Resisting Impacts, Avoiding Collisions, And …, R. J. Speelman Iii, M. E. Kelley, R. E. Mccarty, J. J. Short

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

When birds and aircraft occupy the same airspace at the same time, bad things happen. Annual DoD costs probably exceed $200 Million per year, and dollar losses to world-wide aviation have been estimated at $3 Billion to $4 Billion per year (in US dollars). Much has been done in the past to improve the bird impact resistance of aircraft, and some further improvements would be cost effective on some aircraft. A new manufacturing technology for aircraft transparencies that can increase strength while slashing costs by 80% is one promising approach. However, the “law of diminishing returns” comes into play, and …

Management Of The Yellow Bittern (Ixobrychus Sinensis) On Guam To Minimize Threats To Aviation Safety, Daniel S. Vice, Mikel E. Pitzler

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Wildlife-aircraft collisions caused an estimated $114 million of damage annually to civilian aviation aircraft in the United States between 1993 and 1995 (Cleary et al. 1996). Significant damage to aircraft and crashes may result from the ingestion of one small bird (Cleary et al. 1996). Collisions that do not cause physical damage to aircraft often result in costs related to aircraft downtime while structural inspections are completed. Despite heightened awareness of the hazards wildlife present to aircraft, strikes occur often and occasionally have catastrophic results. The yellow bittern (Ixobrychus sinensis) is a common breeding bird throughout the western Pacific. Yellow …

Pbi/Gordon’S Stronghold™ Plus Bk 800 Broadleaf Weed Control Reduces Mowing, And Eliminates Grass And Weed Seedheads, Earl Tracy

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

We entered the birdstrike arena last year at the Burke Lakefront Airport just prior to the 1998 Bird Strike Committee meeting. Stronghold was applied tank-mixed with Flight Control™ Bird Repellent from Environmental Biocontrol, International ,Wilmington, Delaware. The initial test on the airport was not conclusive, but the idea of the combination appealed to Dr. Richard Dolbeer, Project Leader, USDA , National Wildlife Research Center, Sandusky, Ohio. A second trial plot was established on government property at Sandusky, Ohio. The objective being to quantify the value of Stronghold to the bird repellent activity of Flight Control. The results are to be …

Complete Control Of Nuisance Birds In Airport Hangars, Peter F. Vogt

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fogging of ReJeX-iT7 TP-40 offers a very efficient method for the control and dispersal of nuisance birds from many diverse areas. The amount of the repellent is greatly reduced over any other control method. The method is direct and is independent of the activity of the birds. The applications with any fogger, thermal or mechanical, that can deliver droplets of less than 20 microns, can be manually or fully automated and pose only minimal risks to operators or animals. All birds that became a nuisance and safety problem in the hangars of TWA and AA at LaGuardia, and TWA warehouse …

Bird Strike Risk Analysis On Aktion Airfield (Greece) And Recommendations For Improvements In Bird Strike Prevention, Heinrich Weitz

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

A survey of Aktion airfield in Greece was carried out from 14 to 18 October 1996 initiated by the Flight Safety Division of the NATO E-3A Component Geilenkirchen (Germany) as an reaction to the accident of an AWACS-aircraft on 14. July 1996, initially caused by a bird strike event. The survey of Aktion airfield led to the conclusion that the bird strike risk is extremely high at this airfield. Reasons are:
· The geographical location of the airfield at the Adriatic coast which is a migratory pathway for many birds.
· The location of the airfield on a narrow peninsula …

Evaluation Of Controlling Red-Tailed Hawks (Buteo Jamaicensis) Through Live Trapping And Relocation To Minimize Aircraft Strikes At Canadian Airports, Martin L. Wernaart, Terri L. Groh, Philip J. Roberts

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Central and Southwestern Ontario is one of the largest migratory flyways for raptors in North America. The expanse of airfields and prey availability make airfields attractive to migrating raptors, which may result in an increase in over wintering birds. These birds do not readily scare with conventional wildlife control methods and have high public profile. Even though the strike risk is moderate, raptors routinely make the top ten list for strikes from all bird species (8%) at Canadian Airports. The potential for damage from a collision with raptor species is high due to their size and weight. It has been …

Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)--Part 1, Thomas Alge

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

In worldwide aviation operations, bird collisions with aircraft and ingestions into engine inlets present safety hazards and financial loss through equipment damage, loss of service and disruption to operations. The problem is encountered by all types of aircraft, both military and commercial. Modern aircraft engines have achieved a high level of reliability while manufacturers and users continually strive to further improve the safety record. A major safety concern today includes common-cause events which involve significant power loss on more than one engine. These are externally-inflicted occurrences, with the most frequent being encounters with flocks of birds. Most frequently these encounters …

Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)-- Part 2, Thomas Alge

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Although the perceived threat from the growing geese population in North America has been increasing in recent years (and needs to be addressed), progress appears to have been made in reducing the damaging bird strikes through improved awareness and more effective airport bird hazard control programs worldwide. The following statistics attempt to quantify this progress for selected geographic regions. Reasons for the improvements and lessons learned, if known, are mentioned.

Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)--Part 3, Thomas Alge

This paper focuses on the increasing threat to aircraft and engines posed by the recorded growth in geese populations in North America. Service data show that goose strikes to aircraft and engines are increasing, especially in North America - consistent with the growing resident geese populations estimated by the USDA. Airport managers, along with the governmental authorities, need to develop a strategy to address this large flocking bird issue. This paper also presents statistics on the overall status of the bird threat for birds of all sizes in North America relative to other geographic regions. Overall, the data show that …

Evolution Of The Dfw International Airport Wildlife Management Program –- Lessons Learned, Curt W. Kuehner, John R. Alexander

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

On January 7, 1997, Dallas-Fort Worth International Airport experienced its first large bird strike event, involving the collision of over 350 European starlings with an American Airlines MD-80. This prompted a serious assessment of existing wildlife control procedures, and eventually resulted in the formation of the DFW Wildlife Control Program. The number of reported strikes has dropped from 157 in 1996 to 52 in 1998. The success of DFW’s program is the result of long, hard hours and extensive trial and error. However, wildlife management personnel at other airfields do not have to go through all the growing pains and …

Bird Proofing Hangars, Carl Lahser, Will Summers

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Birds can damage flight line structures and create serious health and safety risks for workers. Many of our structures are old and not designed as bird proof. Many controllable factors are discussed but the underlying principles are to deny birds food, water and access to resting/nesting areas. Various "tools" are discussed including grounds and building maintenance, landscaping, personnel management, chemical deterrents, poisons, and shooting or trapping.

Letter To The Faa Regarding Modified Standards For Bird Strike Impacts, Paul F. Eschenfelder

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The Air Line Pilots Association (ALPA), representing the safety interests of 53,000 professional airline pilots flying for 51 airlines in the United States and Canada, has reviewed the notice of proposed rulemaking (NPRM) in the referenced docket. The NPRM proposes modified standards to which engines are certified with respect to their ability to withstand impacts from birds or similar wildlife hazards. We feel the proposed standard is a step in the right direction, but cannot under any circumstances be considered attainment of a goal. As outlined below, the data used in developing the NPRM has been superseded by more accurate …

Derivation Of Wildlife Values For Mercury, Steven P. Bradbury, John Nichols, Jeff Swartout

Steven P. Bradbury

A procedure has been developed to estimate surface water concentrations of toxicants (“wildlife values”) that will protect the viability of wildlife populations associated with aquatic resources. This procedure was designed primarily to protect piscivorous birds and mammals from compounds that bioaccumulate in fish and was used in the Great Lakes Water Quality Initiative (GLI) to calculate wildlife values (WV) for mercury, DDT/DDE, total polychlorinated biphenyls (PCBs), and 2,3,7,8-tetrachlorodibenzodioxin (TCDD). Published in 1995, and expressed as total mercury in unfiltered water, the final wildlife value (WVf) for mercury derived in the GLI was 1300 pg Hg/L. This value was selected as …

The Western Australian Environmental Protection Authority (Epa) : Its Structure, Functions And Performance 1971-1996, Vincent Cusack

Theses : Honours

This study examines the effectiveness of the Western Australian Environmental Protection Authority (EPA), from its inception in 1971 to 1996. While environmental concerns have risen considerably in recent times, environmental awareness can be traced back to early historical beginnings. Yet, despite this initial awareness it took some time before environmental problems permeated the public consciousness, to occupy the political agenda. However, in the early 1970s, governments throughout the First World responded to research and heightened awareness of environmental concerns, with specific legislation to protect the environment. A common feature of the legislation, was the provision for a main administrative body …
