A wildlife photographer was stunned after she spotted this one-in-a-million non-Albino white squirrel - with "sinister black eyes".
The ultra-rare creature is thought to be one of about five grey squirrels in Britain suffering from leucism - a mutated gene which turns them pure white but keeps their eyes black.
It means the squirrel would not have the same sight problems associated with albino squirrels, who have tell-tale red or pink eyes.
Amateur wildlife photographer Emma Tingay grabbed her camera as soon as she spotted the ghostly squirrel in the garden of her flat in High Wycombe, Bucks. Emma, 40, said:
I've seen albino squirrels before, but never one like this. It's like all the colour was drained from it.
I've seen him a few times since, so we've nicknamed him Snowflake.
There are more than five million grey squirrels in Britain, but wildlife experts reckon fewer than one in a million are born with the recessive gene that causes leucism.
While albinism is caused by a total lack of the skin pigment melanin, leucism is a caused by a reduction in all types of skin-colouring cells.
