You can see them actually figuring stuff out, another bird would just fly in, see there is no food and fly off, but a raven will look around, lift up stuff and try and get into boxes etc. And work together with other ravens.
The main reason i'm posting here is because I saw a raven doing the weirdest thing I have ever seen one do before. I arrived at my mates house and there was a raven on the lawn of the neighbours house. And it was knocking a chicken egg along the lawn! No joke. It got scared when I walked near and flew off but left the egg on the lawn. Where the hell did it get this egg from haha?
Also for the people who don't like crows/ravens because they attack other birds. In Australia, crows/ravens are bullied by a much smaller bird, The Willy Wagtail.
