Hanging a power line up on a tree several years ago, working off a ladder maybe 15' up and something brushed my shoulder and then made a big "Thud" when it hit the ground. I looked down and it was a snake wrapped around a squirrel, squeezing it to death. If those two had landed on my head I would've probably had a heart attack ... but I digress. Got off the ladder and started watching the action, the snake wasn't that big but it finally killed the squirrel and started to eat it. Like you, I figured there was NO WAY that little snake could swallow that squirrel ... but it did. Somewhere, if I can find the old phone I had back then, I've got pictures to prove it, I'll see if I can find them and post it here. Nature offers never ending, fascinating and often unbelievable displays of wonder every single day, we probably miss 99.9% of them.
