A couple of video's in this article show crow's making tools, i've never seen anything quite like this, and thought i would share it with the rest of you. Check out the first and four video to see what i mean.

The vast majority of you will have to watch a small ad before the vid, if you're in the UK you wont; i infact i only discovered the BBC news website used ad's when i've tried to watch video's on there since i've been in Japan.
