A female osprey, the oldest breeding individual in the UK, has returned to a Scottish nature reserve for the 22nd year.

Ospreys live on average 10 to 15 years in the wild, but this bird – known affectionately as Lady– has been positively identified by Scottish Wildlife Trust staff at its Loch of the Lowes reserve in Dunkeld.

The trust's Perthshire ranger, Emma Rawling, said: "I'm delighted to announce that our regular breeding female osprey returned to the nest at Loch of the Lowes. She has been positively identified thanks to her distinctive iris and plumage. It is an amazing achievement for her to return to the area for her 22nd breeding year – making her at least in her mid-20s.

"We are certain she is the oldest breeding osprey in the UK."

Visitor facilities were upgraded over the winter at the Loch of the Lowes.
