Boomers and Knotty heads
In western NC there are two kinds of squirrels, the normal grey variety that lives almost everywhere in the US and what we hunted, and a smaller variety about half the size of the normal grey and red in color, the only name I knew them by growing up was boomer. I honestly have no idea where the name boomer comes from but that is what everyone called them. The common belief was that a boomer was the result of a grey mating with a chipmunk and looking at them it was easy to see where people would get that.
These boomers are fast, I mean really fast, my grandfather said that you needed a hammerless rifle in order to shoot one. If you had a gun with a hammer the boomer would hear the trigger pulled and run around on the the backside of the tree before the hammer fell. I know now that these squirrels are pine squirrels and a completely different species from grey squirrels, not a cross between a grey and a chipmunk. I still see them and there is one that visits my camp on one of my favorite streams every time I camp there, oh and this particular pine squirrel loves ritz crackers. Here is a pic of him, not a very good pic but as I said they are fast and he did not want to sit still. The other is a professionally taken pic so you can actually see what a boomer looks like.
