Urban peregrine populations have grown dramatically as the species adapts to nesting on buildings, bringing both welfare benefits of abundant prey and risks from collisions and human disturbance.
Urban peregrine welfare is largely positive - the species is thriving in cities with abundant prey, warmer urban temperatures, and reduced persecution compared to upland areas. Individual welfare risks include window collision mortality in juveniles and secondary poisoning from rodenticides in prey. Nest platform installation by local wildlife groups provides safe nesting sites that replace or supplement natural ledges, directly improving breeding success. The most important welfare challenge for urban peregrines is managing the interface between building renovation and active nest sites - which requires local knowledge and proactive communication between wildlife groups and building owners.
