阿德利企鹅

冰山和阿德利企鹅，阿德利地，南极洲。

在阿德利企鹅栖息地，你可以看到比想象中阳光更充足的南极，那里还有很多企鹅。

At the Adelie Penguin Rookery , you can see a sunnier-than-expected South Pole landscape with plenty of penguins .

阿德利企鹅来了当然只有雄性

Adelie penguins are arriving . Just the males .

雄性的阿德利企鹅会协助它们的配偶抚养幼仔，如果不仔细观察，两个性别几乎很难分辨。

Male Adelie penguins help their mates rear the young and , without close inspection , the two sexes are nearly indistinguishable .

在早年，南极没有更好得暖冬，而阿德利企鹅的成长是在寒冷的冬天与大量的冰。

In earlier years , chinstraps did better in warmer winters , while Ad é lie penguins grew their numbers in cold winters with lots of ice .

原因就是阿德利企鹅钟爱的那种筑巢栖息地——冰雪溶化后显露出来的岩石海滩在扩张。

The reason is an increase in the kind of nesting habitat Adelie penguins love : rocky beaches revealed by the melting back of snow and ice .

每只阿德利企鹅只有两个蛋，而饲养这些蛋需要一年的投资。但有贼鸥出没，蛋可能会瞬间毙命。

Each Adelie has only two eggs and a year 's investment goes into rearing them . But with skuas on the prowl one can go in a flash .

阿德利企鹅生活在南极大陆和周边许多小岛上。整个冬天他们都会在南极冰盖周围的海上度过。

Adelie penguins live on the Antarctic continent and on many small , surrounding coastal islands . They spend the winter offshore in the seas surrounding the Antarctic pack ice .

对于海豹来说，阿德利企鹅群的壮大可能是好消息，因为他们猎食企鹅，不过前提是海豹能忍受日益升温的海水。

And more Adelies might prove good news for leopard seals , who dine on them . Of course , that 's only if the seals can stand the warmer waters .

如今，筑巢在罗斯岛的阿德利企鹅和帝企鹅被迫要经过长途跋涉，翻越冰山，去获取食物，从而喂养它们在十一二月份的繁衍季节生育的孩子们。

Adelie and emperor penguins nesting on the Ross Island are now forced to walk long distances over the icebergs to obtain food for their chicks , born during the November-December breeding season .

一项来自新西兰和澳大利亚两国研究人员的研究成果显示，自从2010年一座编号为B09B的冰山在南极洲海湾搁浅以来，只有约1万只阿德利企鹅幸存。

A study by researchers from New Zealand and Australia said only about 10000 Ad é lie penguins have survived after an iceberg - labelled B09B - grounded in a bay in 2010 .

因此，在南极洲远海带捕食的企鹅适应得比较好，而只靠从冰架上跃入水中捕食的阿德利企鹅和帝企鹅（如图所示）则面临衰落。

So the penguins in Antarctica that feed in the open ocean are doing okay ; the penguin species that feed by just dropping off the ice shelves , like the Adelie and the emperor ( pictured ), are declining .
