A cool video from a couple of years ago where hacker and writer Joshua Klein talks about the intelligence of crows, and the "crow vending machine" he invented. Yes, wild crows learned to deposit coins in this machine to get peanuts. :-)

The video is ten minutes long, and he doesn't talk much about the vending machine until near the end. He talks mostly about crow intelligence. Very interesting...
