The Chinstrap penguins are found in the Antarctica and several barren islands of the sub-antarctic region. Their name derives from the narrow black band under their heads which makes them appear as if they are wearing black helmets, making them one of the most easily identified types of penguin. Their diet consists of krill, shrimp, and fish, for which they swim up to 50 mi offshore each day. They congregate during winter on barren islands and the Antarctic Peninsula; however, they require solid, snow-free ground for nesting. The chinstrap penguin's primary predator is the leopard seal. The chicks and eggs can be the prey of Sheathbills and Brown Skua.
