penguins spy in the huddle

The Antarctic is home to just 2 of the world's 17 types of penguin.

But a new variety has just appeared-PenguinCam.

As well as a cemera in its body,there's another in its eye.

It just has to wait for its legendary subjects to arrive.

They are emperors- the world's tallest and most regal penguin,standing a meter high.

Their curiosity is encouraging.

They must accept EmperorCam if it is to film their lives up close for nearly a year.

Emperors are a very special penguin-

the only animal on Earth to breed through the Antarctic winter.

As the long journey to their breeding grounds begins,

the penguins accept EmperorCam as one of their own.

Ahead,more penguins are on the march.

They can't delay-their destination lies many miles across a frozen sea.
