Tourists from all over the world have been flocking to The Treshnish Isles off Mull to indulge in the feel-good factor of getting up-close and personal with a puffin.
Boat operator Iain Morrison calls it puffin therapy, having repeatedly witnessed the positive effect these clownish seabirds have had on people over the years.
Mr Morrison, of the Turus Mara boat tour company, has been taking tourists from Mull to Lunga, the largest of The Treshnish Isles, for more than 40 years to see the thousands of puffins gathering there over summer.
He says the word about puffin therapy is spreading fast, with more cruise ships and private boat owners visiting Lunga this year.
Mr Morrison, 66, said: "I ... was the first person to start taking people out there, but it's a lot busier now and the cruise ships are coming in more and more.
"We get a lot of Australians, a lot of Chinese, East Europeans and Americans. I get people emailing me from all over the world saying 'can I have some puffin therapy on such-and-such a date?'"
When he first used the phrase "puffin therapy" it was "tongue in cheek", but he gradually realised the amazing effect puffins had.
He said: "I have taken people to Lunga for years, and I can see that when they have gone ashore they are a wee bit apprehensive. It's as if I have dropped them off on a desert island.
"Then they come back two hours later and they have a big smile on their face, so puffin therapy must work."
Visitors must walk the uninhabited island to reach the puffins.
Mr Morrison said: "When we go to Lunga you can look to the edge of the cliff and there is not a puffin in sight, but once people go ashore the puffins come in from the sea."
