食物的魅力

Here's a new take ontheword \"birdbrain2.\"

Wild crows often probe3 for food using twigs. A captive4 crow named Betty took that common tool use a step further. \"To solve a new problem，she did something no animal had been seen doing before，\" reports animal behaviorist5 Alex Kacelnik.She figured out how to make a hook to pull up a \"bucket\"from a pipe in which researchers had placed some food.She bent a straight piece of wire.Then she poked6 a hook into the pipe where researchers had placed the food， snared7 the bucket's handle， and pulled it out. Dinner is served!

這里將讓你重新認(rèn)識“笨鳥”這個詞的意思。

野生烏鴉通常會利用小樹枝來探尋食物。有只抓來的烏鴉名叫貝蒂，它對這一常用工具的使用作了進(jìn)一步的發(fā)揮?！盀榱私鉀Q一個新問題，她做了件以前從來沒有動物做過的事?！眲游镄袨閷W(xué)家阿列克斯·卡塞里克說。她想法做出一個鉤子，將由研究人員裝有食物的“小桶”從一個筒狀的容器中提上來。她將一段直鐵絲弄彎，然后她把鉤子伸到研究人員放食物的大桶中，鉤住“小桶”的提手，將它提了出來。一頓美餐就緒!
