The largest penguin colony in the world is on Zavodovski Island in the South Sandwich Islands. Approximately two million chinstrap penguins (Pygoscelis antarctica) breed on the slopes of the island which is an active volcano.
Chinstraps get their name from a thin curved line of black feathers which run under their chin. They are also considered the most numerous penguins in the world with a population of around 12 million, mainly found in the Antarctic.
