We call'em mountain boomers here. I don't have a clue why, but that's what we call'em.
Red squirrels aren't chipmunks. They're a squirrel similar to grey squirrels, but colored more like a normal Fox squirrel. They have a little black stripe between the white belly fur, and the red side for. Their tails aren't bushy like a fox, or grey squirrel. They're tails are flat, with most of the fur on the sides.
I've ate plenty of them. When I was younger we ate them all the time. They taste more or less just like grey squirrels, but with just a bit more "rich" taste to them. I figure their taste comes from the pine cone seeds that they feed on. The majority of ours live in bull pine thickets, and from my observations, I'm pretty sure that pine nuts are their main diet.
Try'em!
If you like squirrel meat, you'll love them...
