Crows are generally regarded as intelligent, playful birds, but a new video from Russia that has taken the internet by storm shows just how playful a crow can be. The video, which currently has almost 2 million views, is a simple minute-and-a-half video of a crow standing on jar lid and sliding down a roof - twice.

It is in keeping with the general reputation of corvids, Alan Kamil, from the Center for Avian Intelligence at the University of Nebraska told The Atlantic. I don't know what to make of it scientifically but it is a cool example of a play-like behavior in a corvid.

But is it really having fun? Or does it just appear that way to humans, who tend to anthropomorphize things? Watch and judge for yourself.
