Illegal killing of raptors on shooting estates continues despite legal protection - monitoring programs document the scale of persecution and enable enforcement that protects raptor welfare.
Raptor persecution welfare involves both acute suffering from illegal killing methods and population-level welfare harm from suppressed populations. Poisoning with carbofuran causes convulsions and prolonged death. Trapping causes injury and stress. Shooting at close range may be more immediate but remains illegal. The population welfare impact - harriers breeding at a tiny fraction of potential numbers due to persecution - means the welfare harm extends far beyond individual killed birds to affect an entire metapopulation. Enforcement of existing law, vicarious liability and strong prosecution are the primary welfare interventions. Public reporting of suspicious raptor disappearances and illegal wildlife crime is essential.
