Rare Black Squirrel Sighted

I spotted a black squirrel on the fence in my back yard today. I was doing a little pool maintenance when he skittered over the fence, saw me and froze.We just stared at each other for a while, then he ran away. According to wiki, you find them mostly in the NorthEast, mid-West, parts of Canada and the UK.

Looked kinda like this.

The black fur color can occur naturally as a mutation in populations of gray squirrels, but it is rare- wiki

Since there don't appear to be any black squirrel populations within, say 2-3,000 miles of here, I'm going with "mutation".

Great. I've got a mutant squirrel in my back yard. Possibly a ninja...
