A reader spotted a white squirrel in Conshohocken. If you are wondering, it could be white for two reasons. From Untamed Science:

White squirrels are almost always a white version of the eastern grey squirrel. There are a few types of genetic aberrations that cause the white coats. The first is albinism, caused by a mutation on a gene that codes for pigmentation. Albinos have red eyes. The other is a white morph, caused by a different gene. It is a naturally occurring trait of eastern grey squirrels that is very, very rare.
