Ospreys were once persecuted to near extinction.
Now thanks to more than 50 years of conservation work the birds are thriving again in Scotland.
The latest chicks to be reared in the Tweed Valley in the Borders were tagged before they grow big enough to fly to the other side of the world.
BBC Scotland's Cameron Buttle expected a bundle of fluff when he went to see them.
