A cage design and test method that evaluates the efficacy of tactile avian perch repellents in the laboratory is described. Pigeons, starlings, and house sparrows were tested. Efficacy was demonstrated by a chi-square analysis of the time spent on perches by pigeons and starlings. Activity of individual birds exposed to three to five perches over a 2 to 4-h period was monitored. Pressure-sensitive microswitches were used to monitor activity, while counter and event recorders registered the number of landings and total time spent on each perch. Closed-circuit TV provided a visual record of bird activity without human disturbance. Examples of tests run with four avian perch repellents and pigeons demonstrated the differences in bird response and efficacy of the four products.
