chinstrap penguin Pygoscelis antarcticus

Classy-looking medium-sized penguin. Slender “chinstrap” is unique and unmistakable, but can be difficult to see at a distance; instead, note this species’ white face, dark bill, and cleanly flat-bottomed dark cap. Breeds in colonies on rocky terrain in the Subantarctic, particularly in the southern Atlantic. Winters as far north as far southern Argentina. Gives loud, hoarse barking and braying calls on the breeding grounds.
