Staff at the Loch of the Lowes reserve saw Lady lay the egg in the early hours of Sunday morning
A veteran breeding osprey has laid her 69th egg at a Perthshire nature reserve.
Lady the osprey returned to Loch of the Lowes for the 24th consecutive year, having reared 50 chicks there in the past.
And staff at the centre confirmed that she laid her first egg of the season early on Sunday morning.
The 29-year-old female is thought to be the oldest breeding raptor in the world.
An update on the centre's osprey blog welcomed the "wonderful news" of the latest egg.
It read: "At around 00:30 our nightwatch staff noticed classic egg-laying behaviour, and at 00:47 the female stood up to reveal her new egg.
"It is just as well the birds have built such a deep, snug cup in the centre of the nest as it was so windy last night, the whole nest was rocking.
"The staff and volunteers here are over the moon, and we are so relieved that our beloved female is still breeding at her advanced age."
