The peregrine falcon has made a remarkable recovery from the brink of extinction caused by organochlorine pesticides, and now thrives in urban environments across the UK.
Individual peregrines continue to be illegally poisoned, trapped, and shot by those protecting racing pigeons or gamebirds, despite full legal protection and severe penalties. Lead poisoning from prey that has ingested shot ammunition affects birds throughout their range. Chick theft for the falconry trade, though less common than historically, still occurs. Each illegal killing reduces a recovered but still vulnerable population. Urban nest sites face disturbance from construction work and human interference.
