Via iAlja on twitter I heard about the TED talk on crows by Joshua Klein. I am fascinated by crow intelligence and I found this talk incredible.

It shows a very cool video of a Caledonia crow fashioning a wire hook to use as a tool. It talks about crows who follow Swedish fishermen to steal the bait from the line (or the fish). (Perhaps not surprising when we consider that crafty Israeli crows actually learned to fish themselves.) It also talks about how crows can recognize individual people and act accordingly - researchers at Washington State University who trapped crows found that the crows still recognised them years later and would act aggressively when they spotted them on campus.

Those are all things we know. Crows can learn. But Klein turned this on its head and asked what can we teach them?
