378 TED-ED 乌鸦有多聪明

In one of Aesop’s fables, a crow is searching for water. It spies a pitcher— but the water inside is beyond its reach. So, the crow begins dropping in pebbles. One-by-one, they displace the water, and the crow quenches its thirst. This is just one of many fascinating displays of intelligence from corvids. Katharina Brecht digs into what makes this bold, brainy family of songbirds so smart. [Directed by Irida Zhonga, narrated by Pen-Pen Chen, music by Phil Brookes].在伊索寓言中，有一只乌鸦正在寻找水源。它瞥见一只水罐——但罐中的水却遥不可及。于是乌鸦开始往罐里投掷小石子。一颗颗石子逐渐压低水位，乌鸦终于解了渴。这只是鸦科鸟类众多智慧表现中的一个精彩案例。卡塔琳娜·布雷希特（Katharina Brecht）深入探究了这个勇敢聪慧的鸣禽家族为何如此聪明。
