This video (via Al Dove on twitter), which appears to be from Russia, shows a crow (can anybody confirm the identity of the bird?) engaging in an activity that can only be described as play. There is at least some scientific evidence (behind a paywall) that corvids, as well as some species of parrots and other social birds, do engage in play-like behaviors. This particular instance is remarkable as it does not only show play, but also a form of tool use!
