The Chinstrap Penguin (Pygoscelis antarcticus) is a species of penguin which is found in the South Sandwich Islands, Antarctica, the South Orkneys, South Shetland, South Georgia, Bouvet Island and Balleny. Their name derives from the narrow black band under their heads which makes it appear as if they are wearing black helmets, making them one of the most easily identified types of penguin. Other names for them are “Ringed Penguins”, “Bearded Penguins”, and “Stonecracker Penguins” due to their harsh call.
