Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile Aug 2003

Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

An ongoing challenge for wildlife managers is that target species habituate to or forget about hazing, even though the animals must be somewhat stressed by the hazing. Although stress and efficient memory formation/retrieval are considered to be incompatible, research suggests that the effect of stress on memory is complex. Mild and intense stress can impair memory formation and chronic stress can disrupt memory retrieval. Intermediate stress, however, actually enhances the formation of new memories, particularly long-term memories. Unfortunately, these conclusions are based data from only a very few domesticated species under highly controlled conditions. In nature the variation in baseline …


Risk Analysis Of High-Speed Aircraft Departures Below 10,000 Feet, Bruce Mackinnon, Richard Sowden (Capt.), Terry Kelly Aug 2003

Risk Analysis Of High-Speed Aircraft Departures Below 10,000 Feet, Bruce Mackinnon, Richard Sowden (Capt.), Terry Kelly

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

This paper abridges a Canadian study that examined bird-related safety risks to aircraft climbing to 10,000 feet MSL (mean sea level) at speeds in excess of 250 kias (knots indicated airspeed). The study employed a risk-based framework to examine ornithological information, bird strike data, aircraft-certification standards, aircraft climb performance and aircraft flight profiles. Foremost among its findings, the study determined that populations of high-risk bird species are increasing, that many of these species flock at the altitudes in question, and that aircraft exposure to risk will increase in part because of projected increases in aircraft movements. Examining the appropriateness of …


Risk-Based Modeling To Develop Zoning Criteria For Land-Use Near Canadian Airports, Rolph A. Davis, Terry Kelly, Richard Sowden, Bruce Mackinnon Aug 2003

Risk-Based Modeling To Develop Zoning Criteria For Land-Use Near Canadian Airports, Rolph A. Davis, Terry Kelly, Richard Sowden, Bruce Mackinnon

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Land development in the vicinity of airports often leads to land-use that can attract birds that are hazardous to aviation operations. For this reason, certain forms of land-use have traditionally been discouraged within prescribed distances of Canadian airports. However, this often leads to an unrealistic prohibition of land-use in the vicinity of airports located in urban settings. Furthermore, it is often unclear that the desired safety goals have been achieved. This paper describes a model that was created to assist in the development of zoning regulations for a future airport site in Canada. The framework links land-use to bird-related safety-risks …


The Relationship Of Military Aircraft Activity To Raptors In Central Labrador, Dawn K. Laing, David M. Bird, Tony E. Chubbs, Maj. Gary Humphries Aug 2003

The Relationship Of Military Aircraft Activity To Raptors In Central Labrador, Dawn K. Laing, David M. Bird, Tony E. Chubbs, Maj. Gary Humphries

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Central Labrador is a notable breeding area for Osprey (Pandion haliaetus) and Bald Eagles (Haliaetus leucocephalus). It is also the location of the North Atlantic Treaty Organization’s (NATO) Low level Training Area (LLTA) for fighter aircraft, covering an area of approximately 130,000 km2 over Labrador and north-eastern Québec. Currently, military aircraft based in Goose Bay, Labrador annually conduct 5,000-7,000 sorties and are permitted to conduct up to 18,000 per flying season (DND 1995). The interaction between the two is frequently fatal for the bird and potentially so for the aircraft and pilot. Since the early 1990s, the Department of National …


A Model For Assessing Bird Strike Risk At Proposed New Airports, Jenny Bell, Niall H. K. Burton, Richard Walls, Andy J. Musgrove, Mark M. Rehfish, John Allan, George Wattola Aug 2003

A Model For Assessing Bird Strike Risk At Proposed New Airports, Jenny Bell, Niall H. K. Burton, Richard Walls, Andy J. Musgrove, Mark M. Rehfish, John Allan, George Wattola

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

There are many criteria which need to be assessed when carrying out site selection for new airport developments. One of those which should be assessed is prospective bird hazard and bird strike risk – unfortunately, this is rarely considered as a factor. One reason for this may be the lack of available methodology for such work. This paper presents the methodology used during a recent hazard assessment for a proposed new airport for London. The methodology builds on previously described risk assessment techniques, which were developed for operational airports. It allows an assessment of the likelihood of bird strikes to …


Are Birds Scared By Rotating Mirrors?, Thomas W. Seamans, Scott C. Barras, Zachary J. Patton Aug 2003

Are Birds Scared By Rotating Mirrors?, Thomas W. Seamans, Scott C. Barras, Zachary J. Patton

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Blackbirds (Icteridae) create human health and safety concerns when roosting in large numbers near airports or other urban areas. Therefore, there is considerable demand for effective nonlethal techniques to deter these birds. We tested the effectiveness of rotating mirrors (Peaceful Pyramid®) to keep blackbirds away from decoy traps. Mirrors were in place on traps for 5 consecutive days with control traps having similar a device in place but without mirrors. The total number of birds captured in traps with clear mirrors and control traps did not (P = 0.62) differ. When red mirrors were used, the total number of birds …


Towards Multi-Stakeholder Cooperation In Wildlife Management, Brian E. Henshaw Aug 2003

Towards Multi-Stakeholder Cooperation In Wildlife Management, Brian E. Henshaw

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Wildlife management at airports presents a myriad of challenges. Familiar to many in the field, is the outwitting of wily coyotes, the outsmarting of persistent birds and the outflanking of troublesome deer. Deterrents to barriers, dogs to pyrotechnics, habitat management to habitat removal, an array of increasingly effective measures can be used as part of integrated wildlife management programs to meet the challenge of increasing suburban wildlife populations and their interactions with air traffic. On or off the airfield, the objectives of all stakeholders will not be consistent with best management practices for wildlife management. This is increasingly likely outside …


Application Of Gis Technologies To Wildlife Management At Dfw Airport, Edwin E. Herricks, Jonathan R. B. Fisher, Curt Kuehner, Michael J. Hovan Aug 2003

Application Of Gis Technologies To Wildlife Management At Dfw Airport, Edwin E. Herricks, Jonathan R. B. Fisher, Curt Kuehner, Michael J. Hovan

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

As part of a continuing FAA research program in wildlife hazard assessment and management at airports, a GIS Technical Element – DFW was developed for the Wildlife Hazard Advisory System (WHAS). For the DFW GIS data layers were obtained from public sources and supplemented with airport specific information. Data themes were developed to support general analysis of wildlife habitat on the AOA and adjacent airport property, and analysis was extended to a distance of 25 miles from the airport to accommodate all aircraft in high risk airspace. Over 10,000 wildlife report records were integrated with data on birdstrikes and runway …


Gis And Wildlife Management Activities At Airports, Shelley Gray Aug 2003

Gis And Wildlife Management Activities At Airports, Shelley Gray

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Wildlife observations collected over time at a US Air Force Base (AFB) have been visually displayed through Geographic Information System (GIS) technology. By continuing to expand upon the capabilities of GIS, USDA Wildlife Services has been able to manage the Seymour Johnson AFB airfield and surrounding areas in a practical manner. A Wildlife Hazard Assessment of the AFB used GIS to clearly display the location of birds and mammals observed on the airfield. Baseline themes of natural features (i.e. rivers, woodlands, etc.) were related to wildlife observations to determine areas requiring management. Additionally, GIS has been a useful tool to …

An Automated Acoustic System To Monitor And Classify Birds, C. Kwan, K. Ho, G. Mei, Y. Li, Z. Ren, R. Xu, G. Zhao, M. Stevenson, V. Stanford, C. Rochet

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

Collisions between aircraft and birds have become an increasing concern for human health and safety. More than four hundred people and over four hundred aircraft have been lost globally in recent years, according to a FAA report. To minimize the number of birdstikes, microphone arrays have been used to monitor birds near the airport or some critical locations in the airspace. However, the range of existing arrays is only limited to a few hundred meters. Moreover, the identification performance in low signal-to-noise environment is not satisfactory. Under the support of the US Air Force, Intelligent Automation, Incorporated (IAI) and the …


Through A Bird’S Eye – Exploring Avian Sensory Perception, Robert C. Beason Aug 2003

Through A Bird’S Eye – Exploring Avian Sensory Perception, Robert C. Beason

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

For too many birds their environment includes airfields and aircraft. Knowing avian sensory abilities, researchers can design experiments and develop new devices and techniques to deter birds from aircraft on and away from airfields. How birds perceive the world about them determines many choices, including foraging, predator avoidance, and flight. Most experiments to investigate the sensory abilities of birds have been developed and analyzed using only human sensory capabilities, which often differ markedly from those of birds. My objective is to review and synthesize what is known and what is unknown about avian sensory capabilities. Compared with humans, birds can …

The National Wildlife Strike Database For The Usa: 1990 To 2002 And Beyond, Sandra E. Wright, Richard A. Dolbeer

2003 Bird Strike Committee USA/Canada, 5th Joint Annual Meeting, Toronto, ONT

The National Wildlife Strike Database for Civil Aviation in the USA became operational in 1995 with the initiation of data entry of all strikes beginning in 1990. Since 1995, approximately 46,600 reported strikes from 1990-2002 involving civil aircraft in the USA or for USA carriers in foreign countries have been entered into the database. About 97% of the reported strikes have involved birds and 3% have been with mammals or reptiles. Over 2,000 reported strikes have indicated substantial damage to the aircraft. The database has proven to be an extremely useful source of objective information on the extent and nature …
