Chinstrap penguins near Palmer Station, Antarctica. Chinstraps are a penguin species in the genus Pygoscelis, most closely associated with Adélie and gentoo penguins. Chinstraps often select rocky and ice-free slopes, preferably above nesting gentoos and Adélies. They have been known to bully other penguins from their nests in order to take over the nest as their own.
