A lot of what scientists know about bird song comes from studying zebra finches.

But hide the same loudspeaker inside a toy painted to look like a zebra finch, and his learning improves.

但是， 将同一个扬声器藏在一个看起来像斑胸草雀的玩具里，他的学习能力就会提高。

If isolate zebra finches start a new colony, the young birds pick up the isolate song from their parents.

如果孤立的斑胸草雀开始了一个新的群体，幼鸟就会从它们的父母那里听到孤立的歌曲。

In the zebra finches, the LM did what they expected, responding more to dots that seemed to move from back-to-front.

And after a few iterations, the melody actually starts to resemble the cultured songs sung by zebra finches in the wild.

反复几次之后，旋律实际上开始像斑胸草雀在野外所唱的文化歌曲。

And a study published this week in Science suggests that some incubation calls can even affect how Australian zebra finch embryos grow up.

本周发表在《科学》杂志上的一项研究表明，一些孵化电话甚至会影响澳大利亚斑胸草雀胚胎的成长方式。

Mylene Mariette: In the species that I study, the zebra finch, we found that the parents make a special call when it's hot.

Mylene Mariette：在我研究的物种中，斑胸草雀，我们发现父母在炎热的时候会发出特殊的叫声。

A baby male zebra finch typically learns to sing from its father or other males, starting while it’s still a fledgling in the nest.

一只雄性斑胸草雀宝宝通常会从它的父亲或其他雄性那里学会唱歌，从它还在巢穴中的雏鸟开始。

This means that basic information about the zebra finch song must be stored somewhere in its genome, imprinted there by millions of years of evolution.

这意味着关于斑胸草雀歌声的基本信息必须存储在其基因组的某个地方，经过数百万年的进化而烙印在那里。

She'd take them to the incubator and play them either the zebra finch heat call or a different call, one that the parents make when they change shifts.

她会把它们带到孵化器，给它们播放斑胸草雀的热叫声或不同的叫声，这是父母换班时发出的。

In the bird, seems to be somehow encoded so that when they imitate sounds, they'll shift them to where some kind of an internal image that they have of how a good zebra finch song should be like.

鸟类体中，似乎有某种密码，当它们模仿某些声音时，它们能将密码转换成某种内影像，也就是珍珠鸟好听鸣叫声的样子。

Australian zebra finches, for example, make a special incubation call when their eggs are just about to hatch — starting about 5 days before — but only when it’s 26 degrees Celsius or warmer.

例如， 澳大利亚斑胸草雀会在它们的卵即将孵化时发出特殊的孵化叫声— —大约在 5 天前开始— — 但只有在 26 摄氏度或更高的温度时才会这样。
