Initially it was thought the deer was suffering from albinism, but experts now believe a rare genetic mutation resulting in a condition called leucism has changed the deer's pigmentation.
Weighing in at just over 14 pounds, the creatures are not albino, but are born with a genetic condition known as leucism, which means they have a reduction in all types of skin pigment.
With its beady black eyes, the Polar Squirrel most likely suffers from "leucism," a rare genetic condition in which the body cannot produce pigment on all or part of its skin and fur, Gilman said.
Unlike albinos, which have characteristically red eyes, deer with leucism have normal colouring in their eyes.
The jay was an example of something called "leucism."
Famous as the home of the world's only gators with leucism, Audubon Zoo took care of 18 white baby gators in the late 1980s and out of that batch they still have 10.
White deer are often mistakenly thought to be albinos, but their unusual condition is caused by leucism, a rare genetic pattern that causes a reduction in the pigment in the animal’s hair and skin.
A spokesman for RSPB Scotland said: "Experts had diagnosed the bird as having leucism - a mutation that causes cells to have less or no colouring.
Their condition is the result of a recessive gene and is termed leucism. "
