Dogs Monitor Rare Birds

Dogs wearing global positioning systems (GPS) are being used to help monitor one of Scotland’s rarest birds.

Wildlife Ranger Ally Macaskill is using two German shorthaired pointers to help him track breeds such as black grouse at Perthshire’s Schiehallion estate.

The dogs wear GPS collars as they track the birds. Their precise location is then relayed to a handset carried by Mr Macaskill on the estate
