The red-backed shrike became extinct as a UK breeding bird in the 1990s but is now beginning to recolonise, with welfare considerations around habitat provision and disturbance.
Recolonising shrikes attempting to breed at isolated UK sites face disturbance from birdwatchers, which can cause nest abandonment. The absence of suitable habitat — open scrub with sufficient large invertebrate prey density — means recolonisation attempts in poor habitats fail regardless of disturbance level. Maintaining and creating open heathland and scrub habitat in southern England and Scotland improves the welfare prospects for future recolonisation attempts.
