Tool-Making Crows
推荐理由
A crow, given food in a thin cylinder and a piece of wire, bends the wire into a hook and pulls the food out.
说明
这是2006年由quisling76发布的一部演示,主题归在Animals & nature。它讲的是animal tool use这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:A one-minute clip of the New Caledonian crow Betty bending a straight wire into a hook to retrieve food from a tube. It comes from a 2002 Science study on tool-making in crows.这些读者给出的理由,核心是:HN links it as the clearest demonstration that crows can fashion tools.讲法不绑某一条新闻,过几年仍然可以当材料看。从2009年到2016年,有0位不同的读者在0个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把animal tool use变成能跟着复述的例子。
