Incredible footage shows the transformation a wild stoat undergoes as it changes the colour of its fur ahead of winter in Thixendale, North Yorkshire.

Robert E Fuller documents how the mammal's coat gradually whitens over a few weeks, enabling the stoat to camouflage in the winter snow.

Fuller told Newsflare: "To improve camouflage in snowy conditions, some stoats change from brown to white in the winter months.

"This change can be very gradual and so it was amazing for me as a wildlife artist to watch this female's coat change in colour over the course of nearly 6 weeks."

Watch the amazing process of a stoat (mustela erminea) changing colour from a brown coat to its stunning white winter coat, also known as 'ermine'.
