The kestrel was once Britain most familiar raptor but has declined by 46 percent since the mid-1970s.
Kestrels face welfare threats from loss of rough grassland that reduces vole prey. Intensification of motorway verge management has reduced hunting habitat. Secondary rodenticide poisoning is a growing cause of death. Cold winters cause food stress when frozen ground prevents vole detection. Nesting in old buildings and trees depends on maintenance of suitable sites.
