Abstract:
A study on a population of pigeons on the University of South Africa's Muckleneuk campus was conducted over 2 years. Counts were conducted during a baseline year (March 2013-February 2014) to establish the pigeon population index inhabiting the campus buildings, and again in the management year (August 2014-August 2015) once Eagle Eyes™, Fire (Flash) Flags, bird spikes and a combination thereof were implemented on the buildings. An efficacy reduction percentage was determined for each of the control structures. The total pigeon index on the campus declined by 50 % once the control structures were implemented. Control structures; however, differed markedly in efficacy from each other. Whilst bird spikes indicated the highest efficacy at reducing the pigeon population index, seasonality also influenced the efficacy of the control structure. Quantified understanding of the efficacy of pigeon control measures allows urban management to make informed decisions about reducing pigeon populations.
