Albino animals have a genetic inability to produce pigment molecules such as melanin and carotene. As a result, they are wholly or partially white. And they are generally at a disadvantage when it comes to camouflage. Nevertheless, the can survive. (The image at left is an albino squirrel, photographed in the U.S. by Ian Vargas.)
Glendon Mellow at The Flying Trilobite tells us that there’s a white squirrel living in Trinity-Bellwoods Park in Toronto. It’s an albino. Visit his blog for pictures that he took.
According to the Urban Decoder, albino squirrels have been seen around the park since about 1985. Someone else has reported an albino squirrel at Woodbine & Danforth in Toronto. The image at right is a white, non-albino squirrel.
Please look at the Wikipedia entry for “squirrel” for information about colonies of albino squirrels.
