Back with the Emperors, the females are now firmly in charge.
回到帝企鹅这边，幼雏已经完全交给了母企鹅
Their first big challenge arrives - an Antarctic blizzard.

The penguins protect their chicks by turning their backs to the wind.
企鹅们背对暴风，保护小企鹅
But soon, it's not enough.
但很快，这招就不管用了
The chicks are still exposed to the swirling winds.

To survive the worsening weather, they must huddle closer together.
要想在不断恶化得天气下求生，它们要靠得更近

They start to gather in even greater numbers.
越来越多的企鹅聚集在一起
A huge mass of penguins can share warmth and shelter.
一大群企鹅相互庇护与温暖着对方
But the crush means it's a risky place for a young chick to be.
但是对于年幼的小企鹅来说，拥挤也意味着危险
At first, penguins with chicks circulate on the outside, avoiding the pressure within.
一开始，企鹅带着雏鸟徘徊在部落边缘，避免群集中间的挤压
As the weather worsens, they'll all have to look for a place to tuck in.

While those in the centre are warm and protected, those on the outside are still struggling.
中间的企鹅被周围安全又温暖，边缘的企鹅却仍在挣扎
To share the heat around, the penguins take tiny steps to change position.
为了分散热量，企鹅们挪动着小步改变自己的位置
Waves of movement ripple through the huddle,
企鹅浪在企鹅群里面扩散
giving everyone a chance to have a go in the centre.
让每只企鹅都有钻进中央的机会
The huddle is so efficient, penguins in the inner core can even overheat.
聚集取暖相当有效，有时企鹅在中间甚至会觉得太热
As these penguins try to cool down, the colony starts to break up.
那些企鹅想出去凉快一下，于是企鹅群开始分散
The collapse acts as a release valve, shedding excess heat.
就好比拧开放气闸，多余的热量也因此扩散
But it's dangerous for the chick.

视频及简介

最新的间谍摄像机带给我们全新的视点，帮助我们重新观察这些不可思议的鸟类的行为和极端的生存策略，带我们发现作为一只企鹅的真正意义。紧随成功的北极熊纪录片《冰上侦查》，间谍摄像机在企鹅摄像机上又发展到了新的水平，一系列逼真的电子动物摄像机伪装成企鹅、幼企鹅和企鹅蛋。企鹅间谍来到冰封的南极大陆，来拍摄企鹅帝国。有些摄像机伪装成福克兰岛的跳岩企鹅、南美沙漠的汉波德企鹅的样子。
