In the Brevia section of the 9 August 2002 issue of Science, Weir et al. report a remarkable observation: The toolmaking behavior of New Caledonian crows. In the experiments, a captive female crow, confronted with a task that required a curved tool (retrieving a food-containing bucket from a vertical pipe), spontaneously bent a piece of straight wire into a hooked shape -- and then repeated the behavior in nine out of ten subsequent trials.

  • So glad I never gave up on loving these beautiful birds

  • If we could only get the Greeks to work their food

  • Oh no I didn't but thanks.

  • Crows are awesome! Click my name to see my babies!

  • @LordHannigan didja read the caption? it's a New Caledonian crow.

  • If it had used an already-bent piece of wire supplied by the scientists, it wouldn't have been a big deal. That it _created_ the proper tool for the job is the amazing part.

  • Crow is a former British people probably.

    very elderly.

    bad crow.

  • I think thats a raven. Though crows are of the same family.
