I was out hunting yesterday, leaning against a big pine tree. I happened to look at the trunk of the tree, and I saw it was littered with holes about the size of a nickel. There are plenty of woodpeckers in the area, so that wasn't a surprise. The funny thing was, almost every hole had an acorn wedged in it. I was like, WTH????? I was wondering if it's a woodpecker doing that, or another bird/squirrel taking advantage of the holes.
I did a quick search and found that they are called Acorn Woodpeckers. Pretty funny.
