Run’s chief executive Dr Cat Barlow said: “We’re very sad to confirm Percy’s death.
“In natural golden eagle populations, territorial breeding eagles will attack and kill intruding sub-adults.
“This is what evidently happened here.”
She said the charity was grateful to SRUC and the gamekeepers who “did what they could” for the bird.
“We immediately responded to the alert, but on this occasion Percy’s injuries were severe, and he died before we arrived,” she said.
“This highlights how much gamekeepers engaged in our work care about these majestic birds, and their vital role in supporting the recovery of golden eagles to once again soar in southern skies.”
