Red-backed shrikes became extinct as UK breeding birds in the 1990s, having declined from thousands of pairs to zero in 50 years. Loss of rough grassland, hedgerows, and insect prey caused one of the most complete breeding bird extinctions in UK history.
The extinction of red-backed shrikes as UK breeders represents a total welfare failure at national level following decades of progressive habitat and prey base deterioration. Individual birds that attempted breeding in declining habitat experienced repeated nest failure and food stress. The example serves as a cautionary tale for the welfare consequences of habitat loss that proceeds faster than conservation intervention capacity.
