Feral pigeons live in enormous numbers in cities globally. Management approaches range from lethal culling to contraception. Understanding the evidence for different methods informs welfare-compatible urban wildlife management.
Feral pigeon management reveals how rarely animal welfare is considered in urban wildlife contexts. Pigeons are routinely killed as pests without consideration of whether the killing achieves management goals — which long-term population studies show it does not, since vacated territories rapidly fill. The welfare case for contraception-based management is supported by both its effectiveness at achieving lasting population reduction and its avoidance of the mortality and suffering of lethal approaches. The cognitive abilities of pigeons, including navigation, pattern recognition, and social learning, mean these animals have genuine welfare interests that urban management decisions should respect alongside the legitimate human interests in reducing associated nuisance.
