Chinstrap Penguin

• GeneralIts name comes from the thin black line across its chin, like a helmet strap.
• It sleeps in micronaps: while incubating, the adults guarding the nest rack up more than ten thousand bouts of sleep of about four seconds each over the course of the day, adding up to eleven hours of sleep without ever ceasing to be alert. It is a pattern not known in any other vertebrate.
• The colony on Zavodovski Island, in the crater of an active volcano, holds more than a million chinstrap penguins: it is the largest penguin colony in the world.
