Red kites, one of Britain's most successful conservation stories, continue to be illegally poisoned, particularly on and around grouse moor estates.
Red kites poisoned with carbofuran or alphachloralose experience acute seizures, muscle paralysis, and respiratory failure in a prolonged and painful death. Secondary rodenticide poisoning causes progressive internal bleeding over days to weeks. Poisoning events often kill multiple individuals including other species at the same baiting site. Kites with sub-lethal poisoning exposure show immune suppression, behavioural abnormalities, and reduced breeding success. The recovery of the species makes ongoing illegal poisoning particularly damaging to conservation outcomes and represents preventable suffering.
