An undated photo released by The University of Cambridge shows a rook, a member of the crow family, as it drops stones into a tube to raise the water level and bring a worm into reach, at the Sub-depart
ment of Animal Behaviour at University of Cambridge. In Aesop's fable 'The crow and the pitcher' a thirsty crow uses stones to raise the level of water in a pitcher to quench its thirst. A new study published online Thursday, Aug. 6, 2009 in the journal Current Biology demonstrates that rooks, birds belonging to the corvid, or crow family, are able to solve complex problems using tools and can easily master the same technique demonstrated in Aesop's fable.

剑桥大学,动物行为系发布的一张未注明日期的照片显示一只白嘴鸦,乌鸦家庭的亲属,它正在投下石头在一个管型容器中从而提高水平面,并使水面漂浮的蠕虫进入伸手可及的距离。 在伊索寓言‘乌鸦和水罐’中,一只口渴乌鸦用石头放入水罐提高水平线来止它的干渴。 网上2009年8月6日,星期四出版的一项新的研究, [当前生物]期刊显示出,白嘴鸦,鸟属于蓝鸟科-corvid或者乌鸦家族,它们能使用工具解决复杂问题,并且可能很容易地掌握在伊索寓言展示的同一个技术。
