The illegal killing of birds of prey on UK grouse moors continues to cause acute welfare harm and population suppression.
Raptor persecution causes acute individual welfare harm — poisoned birds die slowly over hours to days; shot birds suffer traumatic injuries; nest-destruction means chick starvation. At population level, the suppression of hen harrier, peregrine, and golden eagle populations over driven grouse moors represents an ongoing welfare failure sanctioned by inadequate enforcement. The evidence base for organised, deliberate persecution is strong; the response from law enforcement and land management agencies has been inadequate.
