Rewilding Red Kites and Raptor Welfare

The red kite reintroduction in the UK is one of Europe's great conservation successes, but ongoing welfare challenges from poisoning and persecution require sustained attention.

Key Facts

Red kites (Milvus milvus) were reintroduced to England, Scotland, and Ireland from 1989, using birds from Spain and Sweden.
The UK population has grown from 0 to over 10,000 birds in three decades — a remarkable conservation achievement.
Poisoning by rodenticides (particularly second-generation anticoagulants) remains a leading cause of red kite mortality.
Illegal persecution through poisoning bait, shooting, and trapping causes individual bird suffering and limits population expansion.
Ingestion of lead from spent ammunition in game carcasses and gut piles causes sub-lethal poisoning affecting neurological function.
Road traffic accounts for significant mortality, particularly in young birds attracted to carrion on verges.
Red kites in urban areas face novel welfare challenges including fishing line entanglement and collision with buildings.
Wildlife crime against raptors in the UK is monitored by the RSPB's Investigations team; conviction rates remain low.

Welfare Considerations

Red kite welfare post-reintroduction demonstrates that conservation success does not eliminate individual animal suffering. The primary welfare concerns — poisoning, persecution, and lead toxicity — are all anthropogenic and preventable. Addressing them requires both legal enforcement and voluntary change: lead ammunition phase-out, rodenticide stewardship, and effective deterrence of illegal poisoning. Individual welfare matters here not only ethically but practically: continued mortality from poisoning limits population growth in some areas and undermines the conservation investment. Sustained community reporting of dead and sick raptors provides the surveillance data needed to target interventions.

What You Can Do

Report dead or sick red kites to the RSPB Wildlife Enquiries line for post-mortem and investigation.
Support campaigns for a complete ban on lead ammunition in the UK and EU.
Advocate for stronger enforcement of wildlife crime legislation.
Choose pest control services that use rodenticides responsibly, minimising secondary poisoning risk.
Support the RSPB, Wildlife Trusts, and Raptor Persecution UK in their monitoring and advocacy work.
