I live in Mahoning County. In recent years, I have seen many black squirrels, especially in western Mahoning Co. Are the black squirrels a separate species, distinct from Fox and Red Squirrels, are are they a sub-species?

They are Gray Squirrel (Sciurus carolinensis) - which can range from all white to all black.
