Which species of squirrels may be hunted?

[waldoj]

Further to #18, which species of squirrels are actually considered to be squirrels under the law? The guide lists gray, red, and fox squirrels, but there are no species of exactly those names. There are 12 species in the BOVA database, including two kinds of gray, two kinds of red, four kinds of fox, and even a "reddish fox" squirrel, which is a bit of both. (There are also four species of flying squirrels, which I suspect aren't included. They're both nocturnal and look nothing like red/gray/fox squirrels.)

My guess is that northern and eastern gray squirrels both qualify as gray squirrels, that both red and talkative red squirrels qualify as red squirrels, and that all four fox squirrels (Southeastern, Delmarva Peninsula, eastern, and reddish) qualify as fox squirrels, but I mustn't be guessing here.
