The Intelligence of CrowsCBC had a great show on television the other night on the intelligence of crows. The study demonstrated how crows can remember faces, not only for a short time, but months later, and how the parents can pass on information like this to their chicks. Plus, they showed how crows not only use sticks to get at food, but learn how to use a stick to get at another stick, which then is used to get the food. The commentator on the show said crows have been watching us for a long time, and perhaps we should be paying more attention to them, as their intelligence is on the scale of chimps. I must admit that watching these crows figure out how to use implements, I wondered if I would have thought of the same thing, so quickly.
If you get a chance to watch it, do! Can't find the link to the documentary, but here is another CBC link with some info and some suggestions for more information.
