From the What the Heck? department:
penelopecat told me that she looked outside to see what sort of critter was making a racket in her yard, and that it was a black squirrel. I said there's no such thing. She said yes, there are two in her yard, and sent a link about Black Squirrels.
So, I read the links and did more research besides. OK, so Black Squirrels exist, but only in eastern Canada, the Midwest of the U.S. and "rarely seen as far west as Nebraska". I said it again: There's no such thing as black squirrels in San Jose, California.
She borrowed my camera, and took the photo you see to the right.
Now, I can't imagine squirrels naturally migrating over the Rockies, so... how the heck did a couple of Black Squirrels get to her yard in San Jose? and does the Fish & Wildlife Commission (or whoever) know about this? Is that who I should call to ask about it?
