Using raptors to disperse pest birds in Victoria

Abstract

Birds are considered to be pests when they damage infrastructure and crops as well as being a health risk and a social nuisance. Here we detail some case studies where we used trained raptors to disperse populations of pest Long-billed Cacatua tenuirostris and Little Corellas C. sanguinea , Sulphur-crested Cockatoos C. galerita and Silver Gulls Chroicocephalus novaehollandiae in Victoria. We describe the situations where the technique works best and compare it with other methods of managing pest birds. Using raptors to disperse pest birds seems to be a cost-effective management tool only when the target area is small, the period over which damage occurs is limited, and when the damage caused by the pest species is costly.
