Urban pigeons are among the most persecuted and misunderstood urban wildlife species, yet evidence-based management can achieve population control more humanely than traditional lethal methods.
Pigeons are persecuted partly because of misconceptions about disease transmission (the health risk to healthy adults is minimal) and partly because lethal control is culturally normalised despite being demonstrably ineffective. Each bird killed is replaced by juveniles from the surrounding population within weeks. The suffering involved in lethal control — poison, trapping, drowning — is significant, and the welfare case against these methods is strengthened by their practical ineffectiveness. Contraception-based management achieves the population reduction that councils seek while eliminating the ongoing welfare harm of mass killing.
