Lead poisoning from ingesting shot-contaminated carcasses is the leading mortality cause in red kites, representing a preventable welfare emergency that requires ammunition reform.
Lead poisoning in red kites causes a prolonged, distressing death over days to weeks. Affected birds show progressive neurological deterioration: weakness, inability to fly, loss of coordination, seizures, and eventual organ failure. The suffering involved in lead poisoning is significant — birds found dying from lead poisoning show severe neurological distress. Treatment with chelation therapy (dimercaptosuccinic acid) can save birds if found early enough, but the window is narrow. The scale of the problem — multiple confirmed lead poisoning deaths per 1,000 birds annually — represents a preventable welfare emergency. The Game and Wildlife Conservation Trust and shooting organisations have committed to voluntary lead ammunition reduction, but binding regulation may be necessary to achieve meaningful change.
