世界上最大的一颗蛋

What Is the Largest Egg in the World? | Object of Intrigue | Atlas Obscura

(John Bates) This is the largest egg in the world.
这是世界上最大的一颗蛋
It resides in our paleontology collection here at the museum
它属于我们博物馆的古生物藏品
because it is something that’s extinct and it’s fairly old.
因为它年代久远 而且已经灭绝了
《世界上最大的一颗蛋》
My name’s John Bates. I’m an Associate Curator of Birds.
我叫John Bates是鸟类馆副馆长
I curate one of the largest bird collections in the world.
我管理着世界上最大的鸟类收藏地之一
Our egg collection has about 60,000 total eggs.
我们收集的鸟蛋大约有60000个
These collections have just this incredible baseline data
而在鸟类繁殖生物学方面
on the breeding biology of birds from various parts of the world.
这些藏品中的基本数据来自世界各地 颇为惊人
This is an egg of an elephant bird,
这是一种大约六七百年前
which is a bird that lived in Madagascar up
生活在马达加斯加的一种
until about six to seven hundred years ago.
被称为“象鸟”的鸟类所下的一个蛋
These birds were bigger than an ostrich by about a meter or so,
这种鸟大概比鸵鸟高一米左右
and twice as wide as an ostrich.
体型有鸵鸟的两倍大
They were probably these incredible, docile animals.
象鸟可能是又庞大又温顺的动物
They had evolved in a place where they literally had no predators,
它们是在一个没有天敌的地方进化而成的
and so, they laid one to two eggs at a time
所以 象鸟一次只产一到两颗蛋
because they could afford to invest all of that in these few chicks
因为它们可以全心投入到仅有的几只幼崽身上
and that’s probably one of the reasons
这很可能就是它们现在
why they’re extinct today.
已经灭绝的原因之一
Humans arrived in Madagascar and these
人类来到马达加斯加时
elephant birds were just completely unprepared
这些象鸟完全应付不了
to deal with the fact that this incredible predator had showed up there.
人类这种惊人的捕食者的出现
They went extinct fairly quickly after that
在那之后 它们很快就灭绝了
and one of the reasons for it is probably the fact
原因之一很可能就是
that they were pretty good eating.
它们非常好吃
You can get an awful lot of omelets out of this.
你可以用象鸟蛋做很多煎蛋卷
This egg didn’t hatch.
这颗蛋并没孵化
That left it in a really pristine state.
它一直处于原始状态
The egg shells of these birds are really thick
象鸟蛋的蛋壳非常厚
and so it’s not that surprising that you would actually
所以能找到几颗长这个样的蛋
have a few out there that look just like this.
也不是什么令人惊奇的事情
A lot of smaller birds are going to be much more fragile
许多较小的鸟类比较脆弱
and you wouldn’t be able to find something like that.
你不可能找到类似于那样的蛋
This egg will probably be on the order of six to seven hundred years old.
这颗蛋大概快有六七百年的历史了
It’s just amazing to have legacy of these birds in the form of these eggs
这些鸟类的蛋很宝贵 拥有它让人感到兴奋
to be able to understand some aspects of their natural history.
因为我们能从中了解到它们的自然历史的某些方面
When you have big series of eggs,
当你有很多鸟蛋的时候
you can start asking what happens with change over time.
你就能发现它们随时间所发生的变化
So, for instance, birds like peregrine falcons and bald eagles
举个例子 在美国东部 像游隼和白头海雕
were declining in numbers precipitously across the eastern U.S.
这样的鸟类数量在急剧下降
Biologists realized that
生物学家发现
females were laying eggs and when they were trying to incubate them,
雌鸟在产蛋后试图孵蛋时
the eggs would crack,
蛋就会开裂
and so one of the ideas they came up with
所以他们想到的其中一个办法
was to go into collections
就是研究收藏起来的蛋
and if you look at a set of eggs collected
如果你去观察DDT投入使用前
way before DDT was being used,
收集起来的一些鸟蛋
biologists realized in areas where DDT was being used,
生物学家发现 在使用DDT的地方
eggshells were dramatically thinner.
鸟类的蛋壳要薄得多
That was one of the pieces of evidence
这也是说服人们
that allowed them to convince people
禁止使用DDT的
that we should ban DDT
证据之一
and it’s an incredible conservation success story
这是一个很好的成功保护案例
because these egg collectors that collected eggs of birds
因为早在19世纪90年代及20世纪初
like bald eagles and peregrine falcons
这些收集者就收集了很多鸟蛋
back in the 1890s and early 1900s,
比如白头海雕和游隼的
had no idea that 50 to 60 years later,
却没想到在50到60年后
their eggs would be used to argue for the preservation of the species
人们会用这些蛋
in a way that’s actually worked.
有效地声援这些物种的保护
