It was taken to be examined by Nick Ridge, of Dorset Wildlife Rescue in Creekmoor, who said: "There is not much doubt that it was shot by an air gun and I am fairly sure it was an air rifle."
The unfortunate bird could not be saved as its main wing joint was shattered. Nobody should be firing an air rifle on Upton Heath, especially so close to the main road."
Nigel Brooks, Dorset Wildlife Trust Warden, said: "Whoever did this was breaking the law - buzzards are protected under the Wildlife and Countryside Act 1981 – and also putting the public in danger. Fortunately this is a very unusual incident and we would appeal to the public to help us and the police to stop it happening again."
Information about this or any other wildlife crime should be reported to the police on 01202 222222. Dorset Wildlife Trust wardens can be contacted on 07970 552679.
