The red kite (Milvus milvus) represents one of Europe's most successful raptor conservation stories—reintroduced to several regions of the UK following extinction in England and Scotland, the population now exceeds 10,000 individuals.
Red kites were once common across Britain but were persecuted to a remnant population of a few pairs in Wales by the 1930s. The Welsh population survived due to the efforts of a few dedicated conservationists and landowners. From 1989, reintroduction programmes released Swedish, Spanish, and Welsh kites into England (Chilterns, East Midlands, Yorkshire, North Scotland) and Northern Ireland. These programmes have been spectacularly successful—England now hosts the largest red kite population outside Germany and Spain.
Red kites are scavenging raptors that feed primarily on carrion and earthworms, supplemented with small mammals, birds, and invertebrates. They are not significant predators of live, healthy livestock—misconceptions about kite predation create unjustified persecution in some areas. Their association with human settlements and willingness to take supplementary food (provided at kite feeding stations in Wales) makes them highly visible ambassadors for raptor conservation.
Despite recovery success, red kites face significant ongoing welfare threats: deliberate poisoning using banned pesticides (carbofuran, alphachloralose) remains the primary mortality cause in some areas; lead poisoning from scavenged deer and gamebird carcasses accumulates to harmful levels; and collisions with vehicles cause mortality particularly in naive young birds habituated to urban environments. RSPB investigations document continuing persecution in areas where illegal poisoning of predators occurs.
Studies consistently find elevated lead levels in significant proportions of red kites tested, with fatal lead poisoning documented. Kites accessing shot gamebird carcasses or gut piles from deer stalking ingest lead fragments. The transition from lead to non-lead ammunition in game management and deer stalking would dramatically reduce lead poisoning across the scavenging raptor community. Voluntary and regulatory lead ammunition bans are essential for long-term raptor welfare.
Red kites' boldness creates novel human-wildlife interactions—swooping on picnics, feeding from hands, landing in gardens. While largely benign, this habituation creates welfare risks for kites conditioned to approach people and vehicles. Supplementary feeding stations in Wales support large winter aggregations, contributing significantly to Welsh tourism. Responsible feeding (appropriate food, no direct hand-feeding) maintains the welfare benefits of supplementary feeding while reducing habituation-related risks.
