Peregrine falcons have colonised urban environments across Britain. Their welfare in cities is generally good, though specific urban risks require monitoring.
Urban peregrine welfare is one of Britain's conservation success stories. Cities provide peregrines with ideal nesting ledges on tall buildings and abundant prey in the form of feral pigeons. Urban pairs typically achieve good breeding success and the birds appear well-adapted to human presence after generations of urban living. The primary welfare threats are illegal persecution (nest disturbance, egg theft, and occasional shooting), building maintenance that inadvertently destroys nests, and the hazards of glass windows and communications infrastructure. RSPB and local peregrine watch groups monitor nests and provide early warning of interference - a practical and effective welfare monitoring system.
