Pigeons, starlings and English sparrows
Methods of controlling domestic pigeons, European starlings, and house sparrows are discussed in detail, with emphasis on urban bird problems. Trapping, exclusion, and roost dispersal by means of frightening devices (pyrotechnic tools such as cracker shells and fuse ropes, in particular) and roost sprays are described in detail. For capture of pigeons, both cage traps and cannon nets are described, with illustrations provided. Case studies are provided of successful dispersal of starling roosts by use of sprays formulated with aqueous ammonia and a wetting agent. Brief mention of use of avicides is included.
