Signs of beavers have been seen close to Perth city centre for what is believed to be the first time.
John Didcock, 75, of Bridgend, was walking on the railway bridge when he saw tell-tale signs of the large mammals on Moncreiffe Island.
He returned the next day with a camera to take pictures of a large tree, which appears to have been gnawed by the animals.
“I had never heard of them within the city limits before and that’s what has surprised me,” he said.
“It’s the first time I have noticed them on the island. I was just out walking with the family when I saw the tree.
“Obviously, they are not put off by the railway line or the noise it makes. It was surprising they had gone into the town.”
Mr Didcock said he was aware of the damage the animals had caused in other parts of Perthshire.
“If they start felling trees in that part of the river then that could cause an issue,” he said. “I think it’s important that people are aware.”
Moncreiffe Island divides the River Tay into two channels as it flows through the city. The railway line to Dundee runs above the island.
Beaver populations in Tayside have become increasingly controversial since the animals were reintroduced to the wild 12 years ago.
A recent Scottish Natural Heritage report revealed more than 400 beavers are now thought to live in the area.
Their lodges and dams can flood farmland, costing farmers and land managers thousands of pounds every year.
