These birds are called Woodwreckers. Their sharp beaks can peck through a whole tree in no time flat, but they don't do it to look for food... they do it for the simple joy of destruction.
Aw thanks! Being the only artist working on this (and only coder, and only writer, and only... you get the idea) has been a pretty big task, but I'm happy there are people who enjoy my doodly programmer-art, haha
