Red kites were reduced to a remnant Welsh population before successful reintroductions across Britain. Their welfare story demonstrates the power of targeted conservation.
Red kite welfare has improved dramatically through reintroduction, but individual birds still face ongoing threats. Secondary rodenticide poisoning — from consuming prey animals containing anticoagulant poisons — causes internal hemorrhage that can be lethal or sublethal. Sublethal exposure impairs flight, reduces hunting ability, and creates chronic welfare harm that predisposes to other mortality risks. Wildlife toxicology surveys consistently find rodenticide residues in a significant proportion of red kites tested post-mortem.
Illegal persecution continues in some areas despite full legal protection. Poisoned baits placed for crows or foxes kill red kites that encounter them. Shooting and nest destruction still occur in some upland areas. Each persecution event represents direct welfare harm and removes individuals from a population still not fully occupying all suitable former range.
