Amazing video of a crow repeatedly sliding down the slope of a snowy roof standing on what looks like a drink coaster. When the slide ends, the crow picks up the coaster and flies back up to the ridge of the roof, positions the coaster in another snowy spot on the roof, and takes another slide.
You can see on the roof the tracks of a bunch of previous slides, so obviously the crow had been enjoying itself this way for some time before the video was shot. I suppose it's possible it was a trained crow doing a trick while its master shot the video...but that sure isn't what it looks like. http://www.youtube.com/watch?v=_2rJoIhgWmw
