Sometimes watching birds I wonder if they are having fun flying. The little chickadees darting through the trees or eagles soaring high. Are they just using flight as a function to get somewhere or to hunt for food? It seems amazing that they couldn't be performing those aerobatics just for the heck of it. I don't think this young fellow was leaving because he was afraid, he just wanted to show off a bit, make me jealous.
