penguins spy in the huddle

The Falkland Islands in the South Atlantic,the breeding grounds of the rockhopper.

Our second remarkable penguin-RockhopperCam-

will record the rockhoppers' arrival,using a camera concealed its eye.

It's joined by an aquatic version that can film both above and below the water.

Its camera-eye captures the penguins' homecoming.

After five months at sea,these rockhoppers are returing

to build new nests where they themselves were born.

They appear at the same time each year,having travelled 400 miles from their fishing grounds off Argentina to be here.

The real challenge begins when they reach the shallows-they must somehow make it ashore.

It won't be easy.These are some of the roughest waters in the world.
