山间的生命极限（2017）

安第斯山脉的最高峰是秘鲁的奎尔卡亚冰川，
The highest shoot in the Andes was to Quelccaya glacier in Peru,
在5700米处
at 5,700 metres.
摄制组希望捕获
The crew are hoping to capture
第一张鸟类在冰川中筑巢的照片
the first images of birds nesting inside a glacier.
我们终于要收拾行装去冰盖了
We are packing up to go to the ice cap at last.
我们要去奎尔卡亚
We're heading up to Quelccaya
经过一周的海拔适应，
after a week of acclimatising to the altitude,
我们得步行大约五个小时，然后我们就应该到了
and we've got to hike about five hours, then we should be there.
所以这很刺♥激♥，同时也有点吓人，因为我们不知道
So it's exciting, and slightly scary at the same time because we don't
我很清楚我们到那里后会发现什么
quite know what we're going to find when we get there.
在摄制组到达之前，
Ahead of the crew,
一组科学家已经在冰川上寻找巢穴
a team of scientists is already at the glacier, looking for nests.
我已经上气不接下气了
I'm out of breath already.
在这个海拔高度，氧气只有海平面的一半
At this altitude, there's only half the oxygen compared to sea level.
我想我把肺留在下面了
I think I left my lungs down there.
我们经常检查脉搏
We're checking our pulses quite often
我们的氧气水平，只是为了确保我们没有临床死亡
and our oxygen levels, just to make sure we're not clinically dead.
- 193. - 215.
那不可能是对的
That can't be right.
由于血氧水平低得危险，
With blood oxygen levels dangerously low,
冰川营地是一个受欢迎的景点
glacier camp is a welcome sight.
这次旅行已经计划了九个月，
This trip has been nine months in the planning,
摄制组仍然不知道科学团队是否找到了巢穴
and the crew still don't know if the science team has found any nests.
很高兴大家都在一起
Good to have everybody together.
是 啊所以我要问，有什么新闻？
Yeah. So I've got to ask, what's the news?
我们找到了雏鸟，我们找到了一个筑巢的地方
We found fledglings, we found one nest building.
好！
Yeah!
我不知道你的情况，但我的心率又上升了一点
I don't know about you, but my heart rate has just gone up a bit more.
非常激动人心
It's very exciting.
带着拍些东西的期望，
With the promise of something to film,
摄制组在营地安顿下来
the crew settle into camp
准备度过他们第一个缺氧的夜晚
and prepare to spend their first oxygen-starved night
在零下10度的温度下
in temperatures down to minus 10.
现在是七点半，
It's half past seven,
我冷极了，
I'm freezing cold,
想在水结冰前刷牙，
trying to brush my teeth before the water freezes,
尽量不要在皮特的奇怪帐篷装置附近吐唾沫
trying not to spit in the vicinity of Pete's strange tent contraption.
-晚安 -晚安，皮特
- Good night. - Night, Pete.
甜美的梦
Sweet dreams.
大约五点半--六点，我刚醒来
It's about half five, six. I've just woken up
在一夜没睡好之后-
after a night of not really sleeping at all -
你整晚都上气不接下气，
you're kind of out of breath the whole night,
就好像你刚刚做了很多运动
as if you've just been doing loads of exercises.
但真正的努力才刚刚开始，
But the real effort is just beginning,
当团队徒步前往奎尔卡亚时
as the team hike to Quelccaya.
母鸟不在附近
The parent birds aren't around.
这个攀冰者
This ice climber
安装窝巢摄像头，不到一个小时
has less than an hour to install a nest camera
须在鸟儿从下面山谷中觅食回来前完成
before they return from feeding in the valley below.
这很难看
It's quite hard to watch.
看起来很不稳定
It just looks so precarious.
冰川融化得很快，脚下不稳定
The glacier's melting fast and is unstable underfoot.
当他倒下的时候我会很高兴的，就这样说吧
I'll be pleased when he's down, put it that way.
回到地面上，摄像机的电线连接到一个拍摄隐蔽处
Back on the ground, wires from the camera are connected to a filming hide.
所以这是关键时刻
So this is the moment of truth.
一切都应该插上电源，准备就绪
Everything should be plugged in, ready to go.
哦
Oh!
在那里我们可以看到
And there we have a view
进入冰川鸟巢
into the glacier bird's nest.
看那个！
Look at that!
所以你可以看到这里，你可以看到
So you can see here, you can see
两个小鸟身上的一点点绒毛
the little bit of fluff on the two chicks.
太棒了，我们有机会了解它们的亲密生活
Brilliant - we've got a window into their little intimate lives
当它们的父母来喂它们时，看看小鸟是怎么长大的
when their parents come in to feed them, see how the chicks grow.
我们拍到多么难得的一些图像啊
What a privileged little view we've got.
这是第一次拍摄冰川鸟巢
This is the first-ever footage of a glacier bird nest.
但成鸟有可能不接受这架相机
But there is a chance the adults won't accept the camera.
如果它们太警惕而不敢进入巢穴，
If they're too wary to enter the nest,
这项任务将不得不放弃
the mission will have to be abandoned.
它们刚刚飞起来，20米，25米，但越来越近了
They just flew up, so they're 20, 25 metres but they're getting closer.
好的，这样我就能看到那只鸟了，
OK, so I can see the bird,
在鸟巢右侧大约三四米处
about three or four metres up to the right of the nest.
她正在检查，这是她周围环境中的一个新东西
She's checking it out. It's a new feature in her environment.
来吧，勇敢点
Come on, be brave.
是的，她在里面
Yes, she's in there, she's in there.
-现在她进来了？ -是啊！
- Now she's in? - Yeah!
-飞出去 -就在镜头前
- Flying out. - Right past the camera.
随着鸟儿们接受了摄像机，现在希望团队
With the birds accepting the camera, the hope is that the team will now
恰好发现隐藏的巢穴中发生了什么
discover exactly what goes on in the hidden nest.
在这次到访之前，
Before this visit,
关于这个物种筑巢的所有已知信息都来自两个巢穴
all that was known about the nesting of this species was from two nests
发现于2014年4月底
found the end of April in 2014.
这项活动以前没有记录
This activity was previously undocumented
这将有助于构建一个描述经过
and will help to build a story
鸟类在冰上筑巢的原因和时间
of why and when the birds are nesting on the ice.
斯宾塞是发现这些鸟独特行为的原始团队的一员
Spencer was part of the original team that discovered the birds' unique behaviour.
他寻找新的巢穴，甚至他到了冰川下
His search for new nests even takes him underneath the glacier.
在这下面有点伤脑筋
It's a little nerve-racking being under here.
我上面有很多冰，我知道它正在融化，并在活跃地移♥动♥
A lot of ice over me and I know it's melting and actively moving.
如果它开始吱吱作响，快跑！
If it starts to creak, run!
科学是斯宾塞家族的传承
Science runs in Spencer's family.
他的父亲道格，多年来一直在研究奎尔卡亚
His father Doug has been studying Quelccaya for years.
自1980年以来，冰川已经缩小了约三分之一
Since 1980, the glacier has shrunk by around a third.
无论魁卡亚在20年、50年还是100年后来到这里，
Whether Quelccaya's here in 20 years, 50 years or 100 years,
很难猜测，
it's pretty difficult to speculate,
尤其是考虑到增长率
especially given the increasing rate
我们正在改变大气层
at which we're changing the atmosphere.
这有点像是在与时间赛跑，试图挽救和理解
It's a little bit of a race against time trying to salvage and understand
这些冰盖还在这里的时候发生了什么
what's going on in these ice caps while they're still here.
回到幕后，有一些好消息
Back in the hide, there is some good news.
等了一周之后，我们终于看到一只小鸟长羽毛了，
So, after a week of waiting, we've finally seen one of the chicks fledge,
这非常令人兴奋
which is very exciting.
现在只剩下一只小鸟，看起来有点不开心
And now there's one chick left, looking a bit sad.
生下来，第一次独自一人-
He's all alone for the first time in his life -
可能不知道发生了什么
probably doesn't know what's going on.
我们希望父母能鼓励它尽快成长
We're hoping the parents can encourage it to fledge soon.
小鸟的家不会持续太久
The chick's home will not last much longer.
来吧，小家伙
Come on, little fellow.
小鸟还没有完全准备好冒险
It's not really quite ready to take the plunge.
-接下来，向你飞来，马修 -准备好的
- Coming up, coming up to you, Matthew. - Ready.
哦，小鸟突然回到了自己的窝里
Oh, he's popped back in his nest.
只是没准备好
He's just not up for it.
哦，小鸟在飞，小鸟在飞
Ooh - chick's flying, chick's flying.
所以我们一直在观察它们，我们看到雪融化了
So we've been watching them and we've seen the snow melting away
在鸟巢周围一点一点地
little by little around the nest.
有一天，鸟巢会从悬崖上滑落下来
One day, the nest is going fall and slide down this cliff face.
幸运的是，它们在那之前就成功了，所以，是的，祝它们好运
Luckily they've managed to fledge before that happened so, yeah, good luck to them.
在这个非常恶劣的环境中
In this really harsh environment.
这对我来说太苛刻了
Which is too harsh for me.
我要下山去吸氧
I'm going to go down the mountain and get some oxygen.
