These penguins that we can find in the islands surrounding Antarctica live in colonies of more than 300,000 specimens and, however, within all this scramble are familiar.
Each penguin, like our fingerprints, has its own song: several syllables that repeat frequently fixed. It seems that penguins who are familiar are able to get to know up to 6% of the song. This capacity that seems surprising is absolutely necessary by the penguins kings, who, by not nesting, have no reference when placing themselves within the colony. According to studies conducted in this regard, the puppies penguins are able to discriminate the call of their mother of 15 m above other 300,000 people and the hum of the wind.
