我们的星球（2019）

‎莱桑岛
Laysan.
‎太平洋上的偏远岛屿
A remote island in the Pacific Ocean.
‎是这只莱桑信天翁雏鸟的家
Home to this Laysan albatross chick.
‎它已准备好进行飞往远洋的首航
He's ready to make his maiden flight to the open ocean.
‎但没有犯错的余地
But there can be no room for error.
‎虎鲨
Tiger sharks.
‎它们迁徙一千公里来到这里
They've traveled a thousand kilometers to get here
‎正好赶上雏鸟初长羽毛的季节
arriving just in time for the fledging season.
‎离开岛屿将是它一生中最危险的旅程
Leaving will be the most dangerous journey of his life.
‎但它的邻居 黑脚信天翁雏鸟们
But it's his neighbors, black-footed albatross chicks
‎率先出发了
that go first.
‎水花飞溅的降落
A splash landing.
‎正是鲨鱼们期待已久的
Just what the sharks are waiting for.
‎现在轮到它了
Now, it's his turn.
‎随着夏风渐劲
With the summer winds picking up
‎天气条件终于适合它伸展翅膀
conditions are finally right for him to spread his wings
‎振翅高飞了
and fly.
‎它有生以来第一次在空中飞翔
He's airborne for the first time in his life.
‎但当微风突然减弱时…
But when the breeze suddenly drops...
‎雏鸟也只得降落
...so too does the chick.
‎没有风
Without wind
‎它无能为力
he's helpless.
‎非常幸运的逃脱
A very lucky escape.
‎它飞起来了
He's off!
‎未来五年间 它可能都不会再着陆
He may not touch land again for five years
‎因为它要飞行千万公里
as he travels hundreds of thousands of kilometers
‎飞越大洋 寻找食物
across the ocean searching for food.
‎片名：我们的星球 2
‎（第二章 追逐太阳）
‎‎双语合并：村儿南
‎我们的星球是由太阳能驱动的
Our planet is solar-powered.
‎太阳光需要八分钟才能到达这里
The sun's rays take eight minutes to reach us.
‎但因为地球的倾斜 ‎阳光不会均匀地照射地球表面
But due to the Earth's tilt, they don't strike its surface evenly.
‎太阳能会在一年中的不同时期
This solar energy arrives in varying amounts
‎以不同的数量到达 ‎这取决于阳光照射的地点
at different times of the year, depending on where it strikes.
‎在北半球
And in the Northern Hemisphere
‎夏季太阳光照的激增
the huge increase that comes with summer
‎引发了无数的旅程
triggers countless journeys.
‎（七月）
‎在七月上旬
In early July
‎欧洲的缀花草地比一年中的任何时候
the flower meadows of Europe receive more sunlight
‎都能得到更多的阳光
than at any other time of the year.
‎这使得蜜蜂忙碌异常
And that makes it a very busy time for honeybees.
‎很少有动物在开采夏季的财富时 ‎比它们还要努力
Few animals work harder to exploit the summer's riches.
‎为了制♥造♥半公斤的蜂蜜
To make just half a kilo of honey
‎一群蜜蜂必须飞行九万公里
a colony of bees must fly 90,000 kilometers
‎造访超过一百万朵花
and visit over a million flowers.
‎几千年来 我们都在利用它们的劳动
And we have taken advantage of their labors for thousands of years.
‎在德国的这处家用蜂巢中
In this domestic hive in Germany
‎六万只蜜蜂 ‎作为一个超级有机体共同工作
60,000 bees are working together as one superorganism.
‎由于较大的蜂后每30秒就产一个卵
And with the larger queen laying an egg every 30 seconds
‎蜂群现在已经爆满
it's a colony that is now bursting at the seams.
‎蜂巢里可能还有四万只蜜蜂正在发育
There could be another 40,000 bees developing in this hive.
‎没有足够的空间给所有蜜蜂
And there just isn't enough room for them all.
‎超级有机体必须要分♥裂♥
The superorganism has to split.
‎准备离开的一派聚集在入口处
Those in the leaving party gather at the entrance.
‎当达到临界规模时 蜂群就开始移♥动♥
And when they reach a critical mass, they begin to swarm.
‎它们必须找到一个新家
They must find a new home.
‎但第一站只是蜂巢附近的集结站
But the first stop is just a staging post close to the hive.
‎几分钟之内 ‎三万只蜜蜂聚集在蜂后周围
In a few minutes, 30,000 bees gather around the queen
‎蜂后现在被蜂群严密保护起来了
who is now shielded by the swarm.
‎在野外 它们易于受到各种元素伤害
Out in the open, they're vulnerable to the elements.
‎所以它们必须尽快另找住处
So the race is on to find somewhere else to live.
‎侦察兵开始出发寻找合适的家
Scouts set off looking for a suitable home.
‎一个大小和高度适宜 ‎恰好与太阳同角度的树洞
A tree hole that is just the right size, height, and angle to the sun.
‎这里看起来可行
This one looks possible.
‎但是太背阴了
But... too shady.
‎太小了
Too small.
‎已经被占领了
Already taken.
‎那这里呢？
Now, what about this one?
‎看起来很有希望
It looks promising.
‎是的 这里正合适
Yes, this will do nicely.
‎下一步就是回到集结站
So it's back to the staging post
‎去说服蜂群的其它成员
to convince the rest of the colony.
‎它通过跳舞来做到这一点
And she does that by dancing.
‎它的摇摆舞相对于太阳的角度
The angle of her waggle dance relative to the sun
‎告诉它们在哪个方向可以找到树洞
tells them in which direction the hole can be found
‎而持续时间让它们知道树洞有多远
while the duration lets them know how far away it is.
‎树洞位置越好 它的表演就越激烈
And the better the spot, the more intense her performance.
‎其它蜜蜂也回来宣传它们的发现
Others return to advertise their finds.
‎但它们的动作比不上它
But their moves just don't cut it compared to hers.
‎大家对它的兴趣越来越浓
Interest grows around her.
‎更多的蜜蜂出发去检视新洞了
And more bees set out to inspect the new hole.
‎这是委员会的寻家活动
It's house hunting by committee.
‎看来它们同意了
It seems they agree
‎它们回来向蜂群的其它成员 ‎传递这个消息
and they return to spread the news to the rest of the swarm.
‎为了做到这一点 ‎侦察兵必须轮流接触每只蜜蜂
To do so, the scouts must touch every bee in turn.
‎令人难以置信的是 仅仅半小时内
And, incredibly, in just half an hour
‎三万只蜜蜂就全部做好了离开的准备
all 30,000 of them are ready to leave.
‎到达后 每只蜜蜂 ‎都在森林中扇动信息素
Upon arrival, each bee fans a pheromone across the forest
‎帮助其它蜜蜂找到新的巢址
helping others to find the new nest site.
‎越来越多的蜜蜂来到新地点
More and more arrive at the new location.
‎所有蜜蜂都加入进来 传播化学信息
All joining in to spread the chemical message.
‎短短几个小时内 ‎整个蜂群就完成迁移了
Within a few hours, the entire swarm has made the move.
‎蜜蜂能够像这样迁移
Bees are only able to move like this
‎是因为太阳的能量 ‎为它们提供了足够多的食物
when the sun's energy provides them with enough food
‎让它们能从零开始重建蜂群
to rebuild their colony from scratch.
‎所以在接下来的几周内
So for the next few weeks
‎它们会像蜜蜂一样忙碌
they will need to be as busy as, well, a bee!
‎（加拿大）
‎七月 越往北走
In July, the further north you go
‎日照就越充足
the more daylight there is.
‎在很短的时间内
And, for just a brief period
‎太阳能如此增加
this increase in solar power
‎把北极苔原变成了丰饶草原
turns the Arctic tundra into a rich grassland
‎吸引了超过一百万只雪雁
attracting more than a million snow geese.
‎它们已经穿越北美
They've traveled the length of North America
‎飞过五千公里的距离
a distance of 5,000 kilometers
‎来到这里繁殖
and they've come here to breed.
‎北极的夏天非常短暂
Arctic summers are short
‎所以雪雁立刻开始产蛋
so the geese start laying straightaway.
‎雌性紧紧地坐在巢上
The female sits tight on the nest.
‎与此同时 雄性会提防敌人
While the male keeps an eye out for enemies.
‎而它并没有等待太久
And he doesn't have long to wait.
‎北极狐常年在此生活
Arctic foxes live here the year-round
‎它们急切地等待着雪雁的回归
and they eagerly await the return of the geese.
‎北极狐的生存依赖稳定的雁蛋供应
The fox's survival depends on a steady supply of eggs.
‎可是雪雁一年只产一窝蛋
But snow geese only lay one clutch a year.
‎并且它们会用生命来保护这窝蛋
And they defend it with their lives.
‎尽管如此 一只北极狐 ‎一个季节就可能偷走超过一千枚蛋
Nonetheless, a single fox may steal over a thousand eggs in a season.
‎尽管损失了不少…
Despite these losses...
‎还是有足够多的蛋得以孵化
...plenty of eggs do hatch.
‎虽然正值盛夏 但这里毕竟是北极
It may be the height of summer, but it's still the Arctic.
‎所以雏雁要跟在妈妈身边取暖
So the goslings stay with Mother to keep warm.
‎但是羽翼之下 空间十分有限
But there's only so much room under one wing.
‎不过 当苔原上的大型居民经过时
Still, it's better to keep out of the way
‎最好还是不要挡路
when the tundra's larger residents pass through.
‎驯鹿本身并不构成什么风险
Caribou themselves pose little risk.
‎但它们的确会带来麻烦
But they do bring problems.
‎灰熊跟着它们 希望能轻松吃上一顿
Grizzly bears follow them in the hope of an easy meal.
‎它们的出现引起了群落的骚动
And their presence causes a stir within the colony.
‎沿路的雏雁都被吸入嘴中
Any chick in its path is hoovered up.
‎由于越来越危险
