A report says the south of Scotland could become a stronghold for Golden Eagles again.
Scottish Natural Heritage has warned that the population will only increase if work is carried out to improve the types of habitat on which the eagles depend.
They have been studying potential threats to the species including illegal persecution and wind farms.
BBC Scotland's environment correspondent David Miller reports.
