This video is long but it's fascinating. And scary. The fact that a crow can figure out how to use a vending machine is scary. Can they learn that if they peck our faces at an outside cafe, we'll leave our food to avoid facial scarring? Can they learn to swarm above picnickers and release a shower of poo causing those picnickers to abandon their food to find safety? Can they learn to manipulate guns to hold our loved ones hostage while we go to a supermarket and get them food? Can they build robot crows to do all of this for them? I should stop. They may be able to learn to read my blog and get all of these ideas.
If you have the time, watch this. It's really good.
