Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Evaluation of Bird Pest Problems at U.S. Army Corps of Engineers Civil Works Projects.
Abstract
A questionnaire was designed and distributed nationwide to U.S. Army Corps of Engineers Civil Works projects to evaluate the nature and magnitude of bird damage and nuisance bird pests. The consensus Bird damage control authorities was that most Civil Works bird problems could be controlled with existing established pest management techniques. The most severe and widespread problem noted during the study was pigeons roosting or nesting on structures such as lock and dam complexes, bridges, and power generating stations. Gulls, swallows, and a few other species were responsible for similar localized problems, usually on a smaller scale. The chief complaint was bird excrement, which was responsible for health hazards, decreased aesthetics, interference with maintenance procedures, safety hazards, and deterioration/corrosion of equipment, materials, and machinery. Avian ectoparasites and damage to building insulation, electrical circuits, and equipment were also important considerations. Their excrement and nests contributed to deterioration and failure in mechanical, hydraulic, and electrical components. Minor problems reported were agricultural depredations (mainly from blackbirds), competition with native bird species (mainly from starlings), scavenging, and predation. Based on the research, it was recommended that a workshop be organized to introduce Civil Works personnel to bird management technologies, and to make them aware of the availability of State and Federal contacts for bird damage control and guidance.
