Rare birds of prey have been caught stealing the underwear of skinny dippers at a popular wild swimming spot in a Highland glen.
The red kites have taken pants and socks to line their nest, including designer brands such as Armani, which have helped keep four chicks warm this summer.
Dave Clement, a gamekeeper on the Gannochy estate in the Angus glens, made the discovery after contacting the RSPB to have the kite chicks ringed and recorded.
It is the second year in a row that he has found a variety of underwear in the nest, high in a larch tree, not far from a gorge in Glen Esk where walkers often strip off to have a swim.
Mr Clement, a member of the Angus Glens Moorland Group, which promotes the benefits of grouse estates, said it appeared that the kites had become more discerning this year by choosing more expensive pants.
He added: "The licensed ringer who went up the tree to the nest said there were Armani pants and another brand as well as socks, which they must have pinched off the swimmers at the local gorge.
"It seems they will take anything to line the nest, then lay the eggs on top, and someone must have gone home minus some underwear.
"It is clearly working because a nest is very successful. Last year there were two chicks, now it's four, and there is clearly plenty of food for them on the estate.
"One of the four chicks is smaller than the others. My daughter Emma has named it 'Georgi' and, obviously, we all hope it survives with the others."
The red kite's habit of "stealing" to make its nest is well known, and nests in England have been found to contain items including England flags, handbags, tea towels, lottery tickets and frilly knickers.
According to the RSPB, underwear, which has been taken off clothes lines in some areas, appears to be a favourite.
The species was formerly persecuted to extinction north and south of the border in the late 19th and early 20th centuries but has made a strong recovery after reintroduction programmes in Scotland and England.
Kestrels and barn owls have also bred successfully on sporting estates in the Angus glens this summer.
