A conservation charity has said that a golden eagle found fatally injured by gamekeepers in the Borders died as a result of "territorial combat" with another bird.

The incident happened on an estate in the region on 1 April this year.

Restoring Upland Nature (Run) - the new home of the South of Scotland Golden Eagle Project - said gamekeepers had done what they could to care for the eagle, named Percy, and had contacted them immediately.
