How does the emperor penguin keep its eggs warm?
----------------------------------------------------------------------
Emperor penguins brood their eggs by holding them on their feet. The
single egg is protected from the Antarctic cold by a fold of loose
skin called the brood patch.
Unlike other penguins, emperors brood their young during the cold,
dark winter months. The female lays one egg, passes it to the male,
then travels out to sea, where she feeds for about nine weeks.
Meanwhile, the male stands still and does not eat, weathering
temperatures as low as -65 degrees Fahrenheit (-54 degrees
Centigrade).
When the female returns, she takes over, receiving the just-hatched
chick from the hungry male, who goes out to sea. While he is gone,
the chick is fed and raised by the mother penguin. By the time the
sea-ice begins to break up, the penguin chick is ready to fend for
itself.
