PHOTOGRAPHIC RECORDS — THEIR IMPORTANCE IN TODAY'S ENVIRONMENTALLY SENSITIVE BIRD MANAGEMENT PROGRAMS

We are living in a day of change. Environmental awareness is a part of our everyday life in a way unprecedented in history. The courts, in their infinite wisdom, have initiated the joint and several liability (deep pocket) rules that make everyone at risk in almost all situations. Bird management programs, by their very nature, are extremely sensitive. Any project, if not evaluated, planned, carried out, and documented properly can result in adverse regulatory agency action, bad publicity, and even fines or lawsuits. Proper photographic documentation can play a vital part in helping to provide the necessary records to help prevent problems and/or defend yourself in case of lawsuit or regulatory action. In the preparation of this paper, we surveyed state pesticide lead agencies, state Department of Conservation (Fish and Wildlife) agencies, some U.S. Fish and Wildlife Law Enforcement personnel, and several individuals to get their reaction to and their comments about this concept of supplemental recordkeeping. Of those responding, a majority thought the concept of supplemental photographic recordkeeping would be an asset to individuals and organi¬zations conducting bird management projects.

Adopting an integrated, flexible approach to reducing the birdstrike risk from Canada geese

Canada Geese overflying the runways at London’s Heathrow Airport have been struck on eleven occasions by aircraft during the last ten years. Four of these occurred during the pre-breeding season and seven during the post moult period. A monitoring study was initiated in 1999 to evaluate the movements of geese around the airport and determine appropriate mitigation strategies to reduce the risk of birdstrike. Moult sites within 13km of the airport were identified. 4,900 moulting geese were caught and fitted with colour rings and radio-transmitters between 1999 and 2004. 2,500 visits were made to over 300 sites resulting in over 10,000 sightings of known individuals. Birds that crossed the airport approaches whilst moving between roost sites and feeding areas in newly harvested cereal crops were identified. Throughout the monitoring period efforts were made to control the risk, but by 2003 it was estimated that 10,000 bird transits of the approaches involving almost 700 individuals occurred during a 50 day period. The knowledge of the movements of ringed and tagged birds was used to inform a revised habitat management, daily roost dispersal and on-airfield bird deterrence programme in 2004. By adopting a flexible approach to management, an estimated 70% reduction in bird transits was achieved. This paper discusses the techniques used to achieve this reduction.
