This is an interesting video about a vending machine for crows. It actually illustrates how adaptable crows are and how they may be trained, by anyone with patience and smarts enough to teach them, to help human beings become a better species upon our planet. It's time for people to realize, they are not the only ones who are able to think and solve problems. Maybe, in a million years or less, we will have to share the top of the food chain with other breeds. Follow the link below for the TED.com, short talk on crows.
