Now, this is completely unprompted; she had never seen this done before.
要知道，它沒有看到過別的烏鴉這么做。
No one taught her to bend this into a hook or had shown her how it could happen.
之前也沒有任何人或者別的烏鴉教它如何把線彎成鉤子；或者告訴過它可以通過這種方式撈肉。
But she did it all on her own. So keep in mind -- she's never seen this done.
這完全是它自己想出來的辦法。請一定記得它以前從沒有學過的哦。
Right. Yeah. All right. So that's the part where the researchers freak out.
就這樣。對，就這樣。這才是研究人員覺得不可思議的地方。
It turns out, we've been finding more and more that crows are really intelligent.
我們發現越來越多的證據表明烏鴉的確是聰明的。
Their brains are in the same proportion as chimpanzee brains are.
它們的大腦占軀體的比例和大猩猩相當。
There's all kinds of anecdotes for the different kinds of intelligence they have.
大家也可能聽過各種各樣的關于烏鴉的趣聞吧。
For example, in Sweden, crows will wait for fishermen to drop lines through holes in the ice.
比如，在瑞典，那里的烏鴉會趁漁人往冰隙里放釣鉤的時候守在一邊。
And when the fishermen move off, the crows fly down, reel up the lines, and eat the fish or the bait.
當漁人走了，它們就飛過去拉起釣鉤，吃掉鉤上的魚或釣餌。
It's pretty annoying for the fishermen.
這可是搞得那里的漁人很煩惱。
On an entirely different tack, at University of Washington a few years ago,
而在華盛頓大學，那里的研究員幾年前做了一個截然不同的實驗，
they were doing an experiment where they captured some crows on campus.
他們在校園里捉來一些烏鴉。
Some students went out, netted some crows, brought them in, weighed and measured them, and let them back out again.
在實驗室里加以標記、稱量，然后把它們放走。
And they were entertained to discover that for the rest of the week, whenever these particular students walked around campus,
而隨后的那個星期，他們驚喜地發現，那些被放走的烏鴉在校園里一見到那些捉過它們的學生，
these crows would caw at them and run around, and make their life kind of miserable.
就會沖著他們鳴叫，并在他們周圍飛來飛去，給他們的生活增添一些小煩惱。
They were significantly less entertained when this went on for the next week.
但之后幾個星期還是如此，他們就不再那么驚喜了。
And the next month. And after summer break.
甚至到了下個月，到了夏季學期結束。
Until they finally graduated and left campus,
到了他們畢業離校了，
and -- glad to get away, I'm sure -- came back sometime later, and found the crows still remembered them.
我相信他們是很高興地離去的--可當他們偶爾回校來看看時，那些烏鴉還是記得他們。
