Buzzards are now the UK's most common raptor but still face illegal persecution on some game estates, with secondary poisoning also a welfare concern.
Illegal trapping and poisoning causes pain and death. Crow cage traps set illegally for corvid control sometimes catch buzzards causing prolonged distress. Secondary rodenticide exposure from vole and small mammal prey causes sub-lethal health effects. Lead poisoning from ingested shot in rabbit prey affects breeding performance. Despite legal protection, persecution continues in some areas affecting local population density.
