Crows Swinging on a Tree Branch

We know from living with cats and dogs that animals like to play and have fun. Still, we are astonished at the rare sighting of wild animals playing games that serve no purpose other than to enjoy it. Crows are quite intelligent birds, being able to use tools and figure out puzzles. Here they have fashioned a game of sorts around swinging on a weeping willow branch. NCARalph caught them on video in his backyard in Massachusetts, and does play-by-play commentary for the game. (via Daily Picks and Flicks)
