Evaluation Of 8 Years Of Fertility Control To Manage Urban Pigeon Populations

It examines the effectiveness of Nicarbazin (NCZ) in controlling urban pigeon populations in Catalonia, Spain, over 24 municipalities for an eight-year period. The NCZ treatment resulted in an average annual reduction of pigeon numbers by 12%, with minimal impact on non-target species, underscoring its specificity. The economic viability of the method was also notable, with pigeon management costs halved in 68% of municipalities within three years of implementation. The study highlights several key insights: NCZ’s specificity minimizes the impact on other bird species, supporting ecological balance. Its economic benefits make it a sustainable approach, encouraging widespread adoption. Moreover, the long-term decline in pigeon numbers demonstrates the treatment’s sustained effectiveness, making it a viable alternative to traditional culling methods. The integration of NCZ with habitat management strategies further enhances its efficacy, ptrventing future population surges.By managing pigeon populations, the study also addresses potential public health risks associated with their overabundance, contributing to safer urban environments.
