Iceland's cliffs will be opened empty in just a couple of days.

By the time the puffinlings emerge from their burrows, the adults have gone.

However, the young puffins are already strong, and take to the skies almost immediately. Beginning their life on the oceans. But there are millions of birds whose first flight is not so easy.
然而小海鹦们已经羽翼丰满，几乎一瞬间就已飞上天空。开始了它们的海上生涯，但是有几百万只海鹦的首次飞行并非一帆风顺。
Over one and a half million guillemots nest here during the summer and these chicks are also about to taketheir maiden flight.

冻土就像一个天然的冰箱，能在将来的漫长冬天里保持食物新鲜。
The guillemots may not be particularly agile on land or in the air, but those that make it to the water, can show where their true ability lies.
海鸠也许在陆地上和在空中显得不是特别灵活，不过当进入水里之后，它们就能展现自己的真正实力了。
Once at sea, the guillemots will only return to land to breed, so the males must spend over a month teaching the young birds to hunt for fish and mollusks below the surface.
一旦入海，海鸠就只有繁殖时才会返回陆地，因此雄性必须花费一个多月时间教后代如何捕捉在水面下的鱼类和软体动物。
They're one of the most numerous seabirds in the northern hemisphere. There are more guillemots on Svalbard than there are people on the whole of Iceland.
它们是北半球数量最多的海鸟之一，斯瓦尔巴德群岛的海鸠数量比整个冰岛的人口还多。
