夜 The night.
一个暗影重重的世界 那里藏着地球上超过一半的动物 A shadowy world that hides more than half the animals on our planet.
在过去的镜头中 我们只能匆匆一瞥动物的生活 Until now, cameras only offered a glimpse into their lives.
但凭借新一代科技 But with next-generation technology,
我们眼中的夜晚和白天一样清晰 we can see the night as clear as day.
有了比人类眼睛敏感100倍的摄像机 With cameras a hundred times more sensitive than the human eye. . .
我们终于能够捕捉到夜晚的美 we can now capture the beauty of night. . .
以全真色彩 in color.
怪谲的自然风光 Alien landscapes.
在黑夜里活跃的奇特生物 Strange creatures brought to life by the darkness.
前所未见的行为 Unseen behaviors.
现在我们能追踪动物的生活 Now we can follow the lives of animals
前往地球最后的荒野 in Earth's last true wilderness.
夜 The night.
肯尼亚马赛马拉平原上 太阳下山了 Sunset over the plains of Kenya's Maasai Mara.
这是非洲最受保护的野生地点之一 One of Africa's most protected wild spaces.
也是地球上速度最快的陆生动物之家 And home to the fastest land animal on Earth. . .
猎豹 the cheetah.
人们一直认为 这种灵敏的猫科动物在白天捕猎 These agile cats have always been thought of as daylight hunters.
它们能在超过1公里外锁定捕猎目标 They target prey from more than a kilometer away.
以每小时100公里以上的速度追捕 And chase it down at over 100 kilometers an hour.
在所有追捕中 成功猎杀的比率不到一半 Fewer than half of all hunts end in a kill.
这个傍晚 这只年轻的公豹失败了 And this evening, this young male has blown it.
幸好它并非踽踽独行 Fortunately, he's not alone.
猎豹通常独自活动 Cheetahs are usually solitary.
但这只豹子有个兄弟 But he has a brother.
这两只四岁大的豹子从出生起就形影不离 Since the day they were born, these 4-year-olds have been inseparable.
它们合作守卫60平方公里的优质狩猎地盘 Working together, they defend a prime 60-square-kilometer hunting ground.
但今天晚上 失败的捕猎意味着 两兄弟浪费了宝贵的精力 But tonight, a failed hunt means the brothers have wasted precious energy
很快又要再次捕食 and must feed soon.
随着日暮降临 As dusk draws in. . .
它们成功捕杀的几率似乎越来越低 it seems their chances of making a kill are fading.
但是整夜跟随两兄弟的脚步 But following these brothers through the night. . .
我们有不同的发现 tells a different story.
凭借低光度摄像机 With low-light cameras. . .
我们终于可以观察猎豹的夜生活 we can now see the cheetah's nighttime world. . .
这为我们打开了全新视角 in a whole new way.
在月光下 Under moonlight. . .
猎豹过着不为人知的夜生活 cheetahs lead a secret nocturnal life.
猎豹兄弟在天黑后很爱玩耍 出乎意料的是 它们也很爱叫 The brothers are playful and surprisingly vocal after dark.
和大部分大猫不同 猎豹不能咆哮 Cheetahs can't roar like most big cats.
但它们能咕噜叫 But they can purr.
家猫咕噜叫是心满意足的表现 In house cats, it's a sign of contentment.
但人们认为 猎豹的咕噜叫也是为了巩固关系 But it's thought cheetahs also purr to strengthen their bonds.
今晚 两兄弟比任何时候都更需要彼此 And tonight, the brothers will need each other more than ever.
它们必须捕猎 They must hunt.
大部分猫科动物是夜行动物 Most cats are nocturnal.
但猎豹的眼睛生来更适应阳光 But cheetahs have eyes adapted for daylight.
所以在黑暗中 两兄弟很难看清环境 So the brothers struggle to see in the darkness.
但如今我们的摄像机 让我们比它们看得更清晰 But our cameras now allow us to see more than them.
被捕食的动物通常尽可能远离捕猎者 Prey animals usually keep as far from predators as possible.
但我们惊讶地发现 到了夜晚 角马另有一种自保的方式 But at night, wildebeest reveal a surprising way to stay safe.
无论猎豹兄弟去哪 Wherever the brothers go. . .
角马群都跟着 the herd follows.
窍门在于让猎豹处于视线所及之处 The trick is to keep the cheetahs in sight at all times. . .
同时尽可能远离它们 while staying just far enough away. . .
以防需要逃跑 to make their escape.
但两兄弟不是第一次玩这个游戏 But the brothers have played this game before.
夜晚视力不佳的猎豹似乎不可能… It seems impossible that a cheetah with poor night vision. . .
在黑暗中进行高速追捕 would attempt a high-speed chase in the dark.
但人们近期发现 But it's recently been discovered. . .
猎豹有三分之一的捕杀是在夜晚进行的 that one-third of cheetah kills take place at night.
这只捕猎高手很快就征服了猎物 A skillful hunter, he swiftly overpowers his prey.
但接下来的情况让我们看到 两兄弟在天黑后的生活并不容易 But what happens next shows how tough life can be for the brothers after dark.
角马群慢慢靠拢 The herd closes rank.
它们能够共同将猎豹从猎物身边赶走 Together, they can drive a cheetah off a kill.
它的兄弟来保护它了 His brother is there to protect him.
不过这只是麻烦的开始 But that's just the start of their problems.
几秒钟的功夫 猎物就吸引了一只鬣狗 一种夜行性食腐动物 Within seconds, the kill attracts a hyena, a nocturnal scavenger.
鬣狗比猎豹强壮得多 Far stronger than a cheetah. . .
一只就足以抵挡两兄弟 one hyena can match both brothers.
它们必须为了守住猎物反抗 They must now fight to keep their kill.
但这个小偷不是独自出动 But this thief is not alone.
马赛马拉的鬣狗群可能多达60只 In the Maasai Mara, hyenas live in gangs 60 strong.
猎豹十分之一的猎物会被偷走 And 1 in 10 cheetah kills are stolen.
在夜晚捕猎 Hunting at night. . .
是完全不同的 is a whole new world.
它们必须再次出击 They will have to try again.
但在天黑后寻觅食物的动物不只有猎豹 But cheetahs aren't the only animals out here searching for food after dark.
在非洲的河岸上 On the banks of Africa's rivers. . .
超过十万头河马离开水域 离开自己安全的家 over 100, 000 hippos leave the safety of their watery homes. . .
踏上不寻常的暗夜之旅 to set out on an extraordinary nocturnal mission.
在白天 河马是出了名慵懒的河中动物 By day, hippos are notoriously lazy river dwellers.
更喜欢在水中歇息 躲避炽热的日光 Preferring to wallow in the water and hide from the hot sun.
但到了晚上 它们非常活跃 But at night, they are remarkably active.
它们循着踏过多次的路径 跋涉10公里 在广阔的大草原穿行 Well-trodden trails lead them ten kilometers out across the open savanna.
在清凉的晚上 它们出来牧食 They come here in the cool of night to graze.
每天晚上能咀食多达50公斤的草木 Chomping through up to 50 kilos of grass and plants per night.
通过这样大量进食 By eating on such a scale,
这些秘密的夜间园丁扮演重要的角色 these secret night gardeners are playing a vital role. . .
塑造草原 shaping the grasslands
为这个丰富多元的生态系统贡献肥料 and fertilizing this rich and diverse ecosystem.
远离了安全的河流 So far from the safety of the river. . .
这里藏着危险 it can be a little risky.
但如果你是个3吨重的除草机 But when you're a three-ton lawn mower. . .
就连非洲最有气势的捕猎者 even Africa's most imposing predator. . .
都要让你三分 has to get out of your way.
没想到它们在夜晚 竟能如此自由地享受草原 With their surprising free rein over the grasslands at night,
我们看到河马的另一面 we are beginning to see hippos in a whole new light.
在晴朗的夜空和满月下 Under clear skies and a full moon. . .
失去了辛苦得来的猎物 猎豹兄弟继续捕猎 the cheetah brothers continue to hunt, having lost their hard-won kill.
但它们不是今晚唯一的猎豹 But they're not the only cheetahs out here tonight.
在它们的领地边缘 On the fringes of their territory. . .
它们的姐妹正在休息 their sister is getting some rest.
这是它很需要的 And she needs it.
它有四只一岁大的幼崽 She has four one-year-old cubs.
它们吃饱喝足 They're already fed.
它现在只想保证幼崽安全 All she wants to do now is keep them safe.
但它能感知到黑暗中的危险 But she can sense trouble in the darkness.
鬣狗 Hyenas.
它们能够杀死年幼的猎豹 They can kill young cheetahs.
虽然它一岁大的幼崽看起来已经长大了 Her one-year-olds might look fully grown.
但它们比成年豹更轻、更弱 But they are lighter and weaker than adults.
还是移动地点比较安全 It's safer to move them on.
一整群鬣狗收到关于这个年轻家庭的消息 A whole gang has got wind of the young family.
鬣狗会争抢领地 会将较弱的敌人赶出栖居地 Hyenas are territorial and will bully weaker rivals off their patch.
鬣狗渐渐接近 The hyenas close in. . .
包围了猎豹一家 surrounding the family.
在所有非洲大猫中 猎豹幼崽的存活率最低 Young cheetahs have the lowest survival rate of any of the large African cats.
它们唯一的防御手段 是让自己看起来比实际更大 Their only defense is to make themselves look bigger than they are.
母亲的最后一招是虚张声势 The mother's last resort is a bluff charge.
它快没办法了 She's running out of options.
但夜晚可能发生最意想不到的事 But the most unexpected things can happen at night.
一头正值情绪暴烈期的年幼公象 A young bull elephant in must.
它重达4吨 睾酮水平 较平常高50倍 正大发雷霆 He's a four-ton giant, raging with 50 times more testosterone than usual.
这些吵闹让它忍无可忍 And he's had enough of all the commotion.
体型最大的陆生哺乳动物 救了速度最快的陆生哺乳动物 The fastest land mammal saved by the biggest.
我们才刚开始了解 We're only beginning to understand
夜晚非洲平原上发生的奇怪事情 the strange things that take place on the African plains at night.
回到两兄弟的领地 Back in the brothers' territory. . .
它们的决心终于有回报了 their persistence has paid off.
它们再次成功 They've made another kill.
又一次 一个熟悉的身影赶到现场 Once again, a familiar character is quick on the scene.
但是这一次发生了不寻常的一幕 But this time, something unusual happens.
鬣狗没有呼唤其他同伴 The hyena doesn't call in the rest of its gang.
而猎豹没有为了猎物和来者对抗 And rather than fight for their kill. . .
而是决定分享 the brothers decide to share.
敌对的双方竟暂时达成休战协议 The two rivals accept an uneasy truce.
终于 两兄弟填饱了肚子 Finally, the brothers get their fill.
猎豹一直被认为是白天活动的猫科动物 Cheetahs have long been considered daytime cats.
但如今我们才发现 But only now are we discovering. . .
它们有着复杂的夜生活 they live complex nocturnal lives.
每天晚上跟随两兄弟的脚步 Following these two brothers night after night. . .
我们发现世界上速度最快的陆生动物 shows a powerful but surprisingly fragile side. . .
在强大之余 竟有如此脆弱的一面 to the world's fastest land animal.
（镜头下的黑夜）
在黑暗中拍摄猎豹捕猎 Filming cheetahs hunting in the dark. . .
是《Earth at Night》团队 遇到的最艰难的挑战之一 was one of the Earth at Night team's hardest challenges.
我以前曾在白天拍摄猎豹捕猎 I've filmed cheetah hunts during the daytime before
（摄像师 内森皮切尔）
但这是我第一次试图 捕捉猎豹夜间捕猎的画面 but this is the first time I've ever tried to get one at nighttime.
猎豹在满月前后 成功捕猎的几率更大 Cheetahs are more likely to make a kill around full moon.
但两兄弟似乎有其他问题要考虑 But the brothers seemed to have other things on their minds.
对 它们来了 Yeah, they're coming.
大多数夜晚 它们都在用气味标记自己的领地 They spent most nights scent marking their territory. . .
就像家猫一样 just like house cats.
猎豹最常见的行为是标记树木 从一棵树到下一棵树 A cheetah's biggest habit is going from one tree to the next tree. . .
再到下一棵树 to the next tree.
我拍了很多这样的画面 And I've got a lot of them doing that.
跟随两兄弟在黑暗中的足迹 Following the brothers in the darkness. . .
团队看到这些猫科动物 需要这么大的空间才能生存 the team saw just how much space these cats need to survive.
但通常它们面对一个难以忽视的问题 But all too often, they were confronted by a glaring issue.
我们的摄像机会拍到城镇 So what we're seeing with our cameras we're picking up towns,
也许在10公里以外 maybe 10 kilometers away.
这提醒了你 It just reminds you
这些非凡的捕猎动物 住在距离人类如此近的地方 how close these extraordinary predators are to living with people.
这些区域很适合 These areas are really good
作为这些捕猎动物的保护区 for the conservation and protection of these predators.
（保育科学家 尼尔斯摩根森）
但与此同时 But at the same time,
随着人口不断增加 土地需求上升 with the increasing human population growth and demand for land,
它们仍然岌岌可危 you know, they are still vulnerable.
世界上仅存约七千只野生猎豹 There are around 7, 000 cheetahs left in the wild.
它们的分布区域每年都在减少 And their range is decreasing year-on-year.
就算是地球上最受保护的野生地区 Even in one of the most protected wild places on Earth,
从我们的夜间摄像机上也能看到 人类永远在不远的地方 our night cameras show humans are never far away.
在黑夜里跟随两兄弟 Following the brothers in the darkness. . .
团队终于等到这个机会 the team finally got their chance.
再来1米左右 好的 慢慢开 Just another meter or so. Okay, just go slowly.
好的 没问题 Okay, no problem.
好 似乎其中一只开始奔跑了 大家稳住镜头 Okay, looks like one of them is starting to run in. Hold still, everyone.
拍到终于成功捕猎的一幕其实挺难得的 It was actually quite amazing to finally get it.
我都开始觉得我们不可能拍到了 I was starting to think we wouldn't.
你必须反应敏捷 You gotta be so quick and hope
希望这是对的时间、对的地点 that you're kind of in the right place at the right time.
鬣狗已经到场 The hyena are coming in already.
难以置信的速度 Incredibly fast.
捕猎技术高超 却如此脆弱 An amazing hunter, but yet so fragile.
跟拍猎豹数月后 After months following the cheetahs. . .
团队捕捉到科学界从未见过的行为 the team captured behaviors new to science.
借此 And in doing so. . .
也揭示了 revealed a secret nocturnal side. . .
这些标志性非洲猫科动物的秘密夜生活 to these iconic African cats.
