This footage was filmed and produced 25 December 2022.

This video shows the incredible camouflage skills of a grey heron blending in with the wall as it soaks up the rays of the sun on Christmas Day in the Vienna Wienfluss, in Austria.

It is a narrow water source and popular with storks and herons that are often seen attempting to catch fish.

This bird was spotted by English jogger Mike Leidig who said: "it is usually there in most mornings, and it never hangs around when there are too many people. But on this occasion, it seems it wasn't very well, maybe it caught a chill, and had found itself a place in the sun to warm up."

He added: "It was amazing that people were cycling or walking past and there were even dogs, and none of them seemed to notice it, even though it was right by the footpath."
