Emperor Penguin, they are such beautiful animals.

They mate at a place called Oamock . After their courtships, the entire population awaits the hatching of the eggs. However, the females leave the eggs with the males and set out through the polar winter back to the sea to find food. After they return the newborn offspring are passed back to them while the males embark on another exhausting march.

One thing I dont understand is that why they have to mate in Oamock? Cant they mate in other places?
