The Prince of Wales, who is patron of the Red Squirrel Survival Trust (RSST), thanked volunteers who work to protect the forest animals. In the letter, the heir to the throne confessed he leaves his jackets with nuts left in the pockets outside in his Birkhall estate for squirrels to eat.
Prince Charles told volunteers who look after the native species he has enjoyed observing squirrels since he was young.
He wrote: “I am so very grateful to all of you for the crucial role you play in this ongoing battle to protect and restore a precious part of our natural heritage.
“They are such inquisitive and delightful characters.
“I take enormous pleasure in having them around – and in the house when I am at home in Scotland.”
He added: “They have even been known to hunt down a few of their favourite nuts left out in an unguarded jacket pocket!”
The Prince of Wales has long been an advocate for environmental causes and recently launched a new initiative to mark half a century of campaigning.
His Terra Carta project aims to persuade businesses to join a charter to help tackle climate change.
HeirPod hosts and royal commentators Omid Scobie and Maggie Rulli discussed how Charles’ new campaign might change the future.
