Here in Australia most people now buy food and drink by tapping their bank cards on a reader. Can't be long now until a particularly smart crow sees this at a beach side shop, and steals a card to copy this. Is a shopkeeper obligated to serve other species? I for one will welcome our new flying thief overlords.

His research claims have been disputed, and an initially favorable NYT story about him ended up being retracted. I think he probably can't be cited anymore as a credible source on the question of crow intelligence.
