How smart are birds?

[downbeatplumb]

In an experiment conducted by behaviorists from the University of Oxford, a small bucket of food was placed inside a tube; the crow was unable to reach the bucket because of the length of the tube. She then picked up a short length of wire, and, after a few futile attempts to snag the bucket with it, bent the wire into a hook and lifted the bucket from the tube. What’s more, the crow repeated the behavior in nine out of 10 subsequent trials.

again involved an out-of-reach bit of food. The crows quickly solved the problem by using a long stick to reach the food. And when the long stick was placed inside a cage, the crows—six out of seven in the experiment–used a shorter stick to push the long stick into a position where it could be picked up. Thus the crows used a tool to manipulate another tool, and it was not just a single individual with this skill. The use of a “metatool” is a behavior difficult even for primates.

My point is they worked out how to do this by themselves. They are very smart creatures.

I don't trust them.
