A pair of white squirrels has set up home in a forest hideaway.
Visitors spotted the two grey squirrels in woodland at Guisborough Forest, on Teesside.
Their snowy pelts are caused by a rare genetic mutation.
Wildlife ranger Cath Brason said: “There has been the odd white squirrel in the population here now and again for the past 30 years, but this is the first time ever there has been two.
“The white gene must be there in the gene pool.
“We don't have to do anything special to look after them, they just dart about in the trees with all the other squirrels.
“Their fur makes them more vulnerable to attack from predators as they have no natural camouflage, so they are doing well to be here at all.”
The squirrels are a one-in-100,000 freak of nature, a Forestry Commission spokesman said.
