A flamingo in Gloucestershire has shunned standing on one leg for floating in water in an effort to cool down.
Experts at Slimbridge Wetland Centre say they have never witnessed the "unusual" behaviour before.
The 52-year-old Andean flamingo began floating when temperatures first soared a few weeks ago.
He now regularly indulges in a mid-afternoon float, with his legs outstretched behind him.
Paul Rose, a flamingo expert at WWT Slimbridge, said: "Lots of flamingos go for a quick paddle around but I've never seen anything like this.
“I first noticed the unusual behaviour as the weather warmed up a few weeks ago so I think it is his way of keeping cool in the heat of the day.
“He floats with his legs outstretched behind him for long periods of time.
“I think it is his way of relaxing, as he seems very content. It is presumably the equivalent to a human floating in a swimming pool on a lilo.”
