A few months ago I was in Cambridge, waiting on a luncheon partner. I was at the rear of a building in my car when I spotted something very odd.
I always have the camera so I was able to squeeze off one shot. Oh, an aside here concerning cameras without viewfinders, they are useless on the water and for action shots.
I got one more shot but it was really moving along the top of the fence, the pic is so shaky it’s not worth posting
I feed the squirrels out back to keep them away from the bird feeders. I buy cracked corn at the feed store, from Jimmy.
Rim shot.
You can practically see through a grey squirrel tail, you hardly notice the squirrel really, they are everywhere.
Black Squirrels are far less common and make for an eyeful.
That was a black squirrel I spotted in Cambridge and they are on the move. It’s still considered a rare sighting in New England apart from specific colonies. A few days ago a neighbor who had just walked home from Hampton Beach spotted two of these fellows along the way and was quite startled as I was in Cambridge. 
The Wiki entry will make you an expert should you happen upon one of these unique rodents locally.
