Dear MEL Topic Readers,
Father penguin uses unique call to distinguish chick
The emperor penguin breeds during the Antarctic winter, incubating and
carrying its egg on its feet in a colony that is far away from the sea where
they can catch fish. Imagine that you’re an emperor penguin coming back from
the sea to your colony after catching fish and bringing it back in your stomach
to feed your offspring. How can you find your mate and chick in a large colony?
Emperor penguins don’t make nests, so there’s no fixed spot where you can meet
up with your family. There’s just a large crowd of all-look-alike penguins
standing around on a flat ice sheet. Interestingly, emperor penguins make a
special two-voiced call that can be used for individual recognition. They use
the call to draw their chicks from the rest to feed them.
Watch the video and learn how penguins identify their chicks.
