I ran into a snake in my backyard today (see my post in the forum) and it was shaking its tail like a rattlesnake would too. I had already been able to tell that it was some kind of colubrid and not a copperhead or something else that we also get a lot of around here. But yeah, I do think that its kind of cute. I think we're the only animals that aren't fooled by their bluff though!
