YouTube user NCARalph captured this amazing footage of young crows keeping themselves entertained by swinging back and forth on a tree branch.
“These are wild crows playing in our back yard north of Boston, MA, USA, swinging upside down on a willow branch and knocking each other off. I believe these are a group of young fish crows who have been playing this game a few times a week for the last couple of weeks, always using the same branch.”
