Urban peregrine falcons preying on city pigeons represent a natural predator-prey relationship that raises welfare questions about prey animal suffering.
Wild predation represents a natural welfare trade-off - peregrine hunting is natural behaviour while pigeon prey experience acute death. The welfare calculation favours peregrines living wild lives over persecution to protect feral pigeon populations with their own significant welfare challenges from disease and injury. Supporting urban peregrine welfare means accepting their predatory role in city ecosystems.
