Chinstrap Penguins often live on large icebergs on the open ocean. One colony on the South Sandwich Islands is said to contain over 10 million birds. They are a stable population and were last estimated to include about 7.5 million breeding pairs. (Barham and Barham 1996, Welch 1997, Woehler and Chippingdale 2000).
