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.
每天晚上 全世界各地的城市 点亮了黑暗的夜空 Each night, across the planet, our cities illuminate the darkness.
城市的灯光闪亮耀眼 Their lights burning brighter than ever before.
当我们入睡时 And whilst we're asleep,
动物正在这个新的霓虹世界寻找机会 animals are making the most of this new neon landscape.
芝加哥 一个600平方公里的光之都市 Chicago, a 600-square-kilometer city of lights.
这个满是混凝土和玻璃大厦的迷宫 This maze of concrete and glass canyons
对于地球上速度最快的动物而言 是一个完美的家园 provides the perfect home for the fastest animal on Earth. . .
游隼 the peregrine falcon.
游隼通常在白天捕食 Peregrines are usually daytime predators,
但在芝加哥 一些游隼已开始在夜晚捕食 but here in Chicago, a few have started to hunt at night.
每年的一些固定时期 它们在入夜很久后依然活跃 And there are certain times of year when they're active long after dark.
每年春天 数百万只小鸟在城市上空飞过 Each spring, millions of small birds pass over the city
为了繁殖向北方迁徙 on their migration north to breed.
它们在晚上飞行 因为气温较低 They journey at night, when the air is cooler,
这有助于贮存能量 which saves them energy.
但当它们飞过城市上空时 灯光让它们混乱 But as they fly over the city, the lights confuse them.
它们被灯光吸引 于是改道向下 Mesmerized, they're drawn down. . .
落入这只雌鸟的捕猎场 and into this female's hunting ground.
从前 人们从未拍过 这些捕猎者在夜晚捕食的画面 Until now, nobody has ever filmed these predators hunting at night.
在黑暗中突击快速移动的猎物 需要极精准的动作 Striking fast-moving prey in the dark takes absolute precision.
它的最佳策略是飞到灯火通明的城市上空 Her best strategy is to climb high above the glowing city. . .
锁定下方的猎物 spot her prey below,
然后俯冲 and then nose-dive. . .
化身一颗时速300公里的霓虹子弹 becoming a 300-kilometer-an-hour neon bullet.
将光滑的玻璃大厦作为掩护 Using the sheer glass buildings as cover,
它能在阴影中伏击猎物 she can ambush her prey out of the shadows. . .
一路追逐它们进入空旷的夜空 让它们无处可藏 chasing them into the open, where there's nowhere to hide.
但猎物不是给它自己的 But the kill isn't for her.
这只猎手也是一位母亲 有三只嗷嗷待哺的幼鸟 This hunter is also a mother with three hungry chicks.
迁徙季已经开始一段时间了 With the migration well underway,
这只雌鸟和它的配偶必须继续捕猎 this female and her mate must keep hunting.
它们能在一小时内捉到十只鸟 令人惊叹 Amazingly, they can catch ten birds in just one hour.
60年前 芝加哥没有游隼 Sixty years ago, there were no peregrines in Chicago.
今天 单单是市中心就有十对筑巢的游隼 Today, there are ten nesting pairs in downtown alone.
夜晚的都市灯光是它们的好帮手 Helped by the lights of the city at night.
在世界各地 夜晚的降临 都为城市区域带来巨大改变 Across the world, nightfall brings great change to our urban areas.
每天晚上 数十亿灯泡亮起 Each night, billions of light bulbs burst into life.
如今 一个街灯的亮度 A single streetlamp can now be 200 times stronger
可能比满月的亮度强200倍 than the light of a full moon.
地球的夜晚从未如此明亮 With the nights lit up like never before,
而城市也为一些勇敢的动物 提供意想不到的机遇 the city offers surprising opportunities for a few bold animals.
洛杉矶有二十五万个游泳池 Los Angeles has a quarter of a million swimming pools.
到了夏天 温度高达摄氏38度左右 In summer, when temperatures hit 100 degrees. . .
这些泳池的水成了救命索 all this water is a vital lifeline. . .
让一些意想不到的访客解渴 for some unexpected visitors.
从螽斯… From bush crickets. . .
到啄木鸟 to woodpeckers.
灰狐 Gray foxes.
就连害羞的骡鹿 在口渴至极时也会造访这个后院游泳池 Even shy mule deer are thirsty enough to risk a visit to this backyard pool.
但有一种午夜来客 是你想不到会在洛杉矶找到的 But there's one midnight visitor you'd never dream of finding in LA.
美洲黑熊和它一岁大的幼崽 A black bear and her year-old cubs.
它们来这不只是为了解渴 And they're here for more than just a drink.
在热天的城市中 When it's hot in the city,
它们喜欢游个泳 凉快一下 they like a swim to cool off.
当我们在睡觉时 While we're asleep,
这个黑熊家庭在享受私家游泳池派对 this family can enjoy their very own pool party.
幼崽跟着妈妈的脚步 已经掌握了狗刨式游泳 Following Mum, these cubs have perfected their doggy paddle.
但为人父母的都知道 But, as every parent knows,
和孩子一起游泳并不能放松 swimming with the kids isn't all that relaxing.
没有双胞胎碍事了 With her twins out of the way,
熊妈妈终于可以享受难得的独处时光 Mum finally gets the chance for some much-needed me time.
随着城市发展壮大 As our cities grow,
越来越多的熊在城市区域栖居 more bears are finding themselves in urban areas.
难以置信的是它们调整了自己的生物钟 And incredibly, they're shifting their body clocks
让自己在夜晚更加活跃 to become more nocturnal.
对于这些熊而言 洛杉矶的夜生活很滋润 For these bears, LA nightlife is sweet.
天黑后 动物们寻找的不只是水 It's not just water that animals are seeking out after dark.
夜晚也是偷食的好时机 Nightfall is also the perfect time to steal a meal.
夜间犯罪生涯让一种城市动物 A nocturnal life of crime is making one city creature. . .
越来越聪明 smarter than ever.
浣熊 The raccoon.
今晚 浣熊母亲带着两个幼崽潜入城市 Tonight, this mother is leading her two young kits
给它们夜晚偷盗行动的初体验 out on one of their first night heists.
它们的地盘是多伦多郊区的三个方形街区 Their turf: three square blocks in suburban Toronto.
它们盗贼一样的面具能吸收光 减弱强光 Bandit-like face masks absorb light, reducing glare,
让它们能在黑暗中看清东西 which helps them see in the dark.
它们并不挑食 And they're not fussy eaters.
但菜单上不只有垃圾 But it's not just garbage on the menu.
这两只聪明的小浣熊还在学习 These bright young raccoons are in training
成为技术高超的后院小偷 to become skilled backyard burglars.
首先 它们必须找到进入后院的最佳路线 First, they must figure out the best way to break in.
接下来 它们必须练习使用灵活的小手 Next, they must practice using their dexterous little hands
抓到美味的食物 to get at tasty morsels.
它们有无穷的好奇心 这让它们成为犯罪大师家族 They're endlessly curious, making them a family of criminal masterminds.
直到某个成员掉链子 Until somebody lets the side down.
像这样大胆而复杂的夜间偷袭行动 Daring and complex night raids like this
让城市浣熊比它们的乡野表亲们更聪明 have made city raccoons even smarter than their country cousins.
多伦多目前有十万只浣熊 And with 100, 000 of them now in Toronto,
掀起了一阵郊区犯罪潮 it's a suburban crime wave.
有许多故事讲述了动物如何被迫适应 There are many stories of how animals must adapt
夜晚的都市生活 to live in our cities at night,
但其中一个故事格外特别 but one is truly extraordinary.
在美国最大的都市丛林之一 住着一只食物链顶端的捕猎者 A top predator in one of America's largest urban jungles.
距洛杉矶市中心不远处有一座山丘 名叫韦尔杜戈山 A stone's throw from the heart of LA lies Verdugo Mountain.
白天 这里是登山者最爱的地点 By day, it's a favorite spot for hikers.
但远景夜间摄像机 But remote night cameras. . .
拍下了令人意想不到的秘密夜生活 capture a surprising and secret nightlife.
一群郊狼 共有六只 夜晚在山丘游荡 A pack of coyotes, six strong, prowl the hills at night.
为了避开人类 它们变得在夜间更活跃 They've become more nocturnal to avoid humans,
以小哺乳动物为食 surviving on a diet of small mammals.
安静的夜晚也是美国大山猫现身叫唤 以吸引交配对象的时候 And the quiet of night is also when bobcats call to attract a mate.
但这里有一种动物尤其善于隐藏行踪 But there's one animal here that's so elusive
以至于没有人见过它的身影 no human has ever set eyes on her.
美洲狮 A mountain lion.
这只大猫住在洛杉矶的市中心附近 A big cat living in sight of downtown LA.
在隐藏摄像机第一次捕捉到它的画面之前 Until she was first caught on a hidden camera,
没有人知道它住在这里 no one even knew she was here.
人类邻居叫它妮基塔 Her human neighbors have named her Nikita.
它在深夜四处巡视 She patrols in the dead of night,
安静地闯入 尽情享用都市的设施 silently trespassing to make the most of the city's amenities.
山上也栖居着大型骡鹿 Sharing these hills with large mule deer. . .
所以它不缺猎物 means there's plenty for her to hunt.
我们的摄像机捕捉到它的藏身地 And our cameras reveal the hiding places
它在那里不受打扰地享用猎物 where she devours her prey away from prying eyes.
但妮基塔最让人震惊的一点 But the most astonishing thing about Nikita
是它能够在城市环绕的情况下存活下来 is how she survives, surrounded by the city.
如今 它所栖居的山地四周 Today, her mountain home is encircled
筑起了混凝土建筑和高速公路 by a barrier of concrete and freeways.
其他美洲狮的栖居地 面积超过200平方公里以上 Whilst other mountain lions wander over an area of 200 square kilometers,
妮基塔却能在四分之一的面积内茁壮生长 Nikita manages to thrive in a space only a quarter of that size.
它的领地是灯海中的一块黑暗岛屿 Her territory is a dark island amongst a sea of lights.
然而 令人惊叹的是 它已经在这里生活了十多年 But amazingly, she's been surviving here now for over a decade.
妮基塔的未来也许充满未知数 Nikita's future may be uncertain.
但目前 洛杉矶的这只神秘大猫 仍然在阴影中游荡 But for now, LA's secret big cat still prowls the shadows. . .
在人们沉沉睡去时活跃着 whilst we're sleeping.
它是城市的终极幸存者 The ultimate city survivor.
（镜头下的黑夜）
在芝加哥 On location in Chicago,
团队第一次拍摄在夜间捕猎的游隼 the crew filmed peregrine falcons hunting at night for the first time.
但故事只讲了一半 But this was only half the story.
现在是迁徙季节 It's migration season,
超过250种小型鸟类飞过芝加哥 when over 250 types of small bird fly over Chicago.
它们的迁徙路线 早在芝加哥建成之前就已经定下了 Following the same route from a time long before the city was even built.
灯光的反射让鸟儿眩晕 The reflected lights dazzle the birds,
许多鸟会撞上玻璃窗户 and many hit the glass windows.
（芝加哥）
黎明到来时 志愿者 安妮特普林斯搜索城市的街道 As dawn arrives, volunteer Annette Prince searches the city streets,
希望拯救受伤的鸟儿 hoping to rescue any injured birds
并记录下未能存活的鸟儿 and recording those that didn't make it.
这是我们今早发现的红喉北蜂鸟 This is a ruby-throated hummingbird that we found just this morning,
我们到街上后最先发现的 very first thing when we arrived.
从遥远的南美洲或中美洲 一路飞来这里的小鸟 A little bird that flew all the way here from South or Central America,
它曾飞越墨西哥湾 across the Gulf of Mexico.
马上就到达它们的繁殖地点了 却在这里结束 挺悲伤的 And to have it end when they're almost to their breeding grounds is pretty sad.
（芝加哥鸟类撞击保护会 安妮特普林斯）
但它们更让人觉得难得 因为它们是幸存者 But they are even more precious 'cause they are the survivors.
这是最棒的红喉北蜂鸟 This is the best little ruby-throated hummingbird
虽然它没有到达繁殖地点 that didn't make it to his breeding ground.
在芝加哥市中心各处 Across downtown Chicago,
安妮特的团队寻找需要帮助的小鸟 Annette's team are searching for birds that need help.
捉到了 Got him.
是一只橙顶灶莺 It's an ovenbird.
它来自南美洲或中美洲 This guy comes from South America, Central America.
（芝加哥鸟类撞击保护会 约翰凯利）
它很可能飞越墨西哥湾才来到这里 He probably flew across the Gulf of Mexico to get here.
它们飞了这么远的距离却在这里撞上大楼 So, this It's amazing they go this far and then hit a building here.
在清晨巡视的过程中 During their morning patrol,
安妮特和团队成员找到的每只小鸟 都有属于自己的悲伤故事 each bird Annette and her team find has its own sad story.
它很不安 你看到它张嘴呼吸的样子吗？ He's very stressed. You see how he's open-mouth breathing like that?
在大量鸟类迁徙的日子 On very heavy days of migration,
我们最多发现、救援300只受伤的小鸟 we've had as many as 300 birds injured and rescued,
还有300至400只小鸟在发现时已经死去 and another 300 to 400 birds found dead.
所以在大量鸟类迁徙的日子 一天就能找到数百只小鸟 So we can find hundreds of birds on single heavy days of migration.
一年内 In one year,
安妮特的团队在芝加哥市中心 收集了超过五千只鸟 Annette's team collected more than 5, 000 birds from downtown Chicago.
三分之二在发现时已经死去 Two-thirds of them were found dead,
因此 芝加哥是美国鸟类撞击事故 死亡率最高的城市 making Chicago the deadliest city for bird collisions in America.
-在街上找到一只 天啊 . . . got one on the street. Oh, boy.
今天的清晨巡视结束了 As this morning's patrol comes to an end,
安妮特的团队收集了幸存的小鸟 Annette's team gather the birds lucky enough to get a second chance.
看 它是不是很漂亮？ Look at that. Isn't he beautiful?
是一只黄鹂 是雄鸟 它正在长婚羽 It's an oriole. It's a male. He's getting his breeding plumage.
你可以看到它的头上仍有一些斑点 You can see he still has a little bit of speckling on his head.
它飞了数千公里来到这里 它成功了 So he has flown thousands of miles to get here, and he's made it.
希望我们能放飞它 它会飞去森林保护区 And hopefully he's gonna get released and go off into a forest preserve,
它可以在那里找到夏季筑巢的理想地点 where he'll find his way to where he wants to set up his nest for the summer season
抚养雏鸟 and raise his young.
芝加哥有了新的希望 In Chicago, there's now hope.
100栋大楼已同意在迁徙季熄灯 One hundred buildings have agreed to turn off their lights during the migration. . .
保护一万只小鸟的生命 saving the lives of 10, 000 birds.
数量高达十亿只鸟 With a staggering one billion birds
每年撞上美国各地的大楼 hitting buildings across America every year,
许多种类的未来也许就寄望于 关上开关这个简单的举动 the future of many species could depend on the simple flick of a switch.
