Chatham penguin

The Chatham penguin (Eudyptes chathamensis) was a species of penguin, now extinct. It is known only from subfossil bones, but may have become extinct as recently as the late 19th century as a bird kept captive at some time between 1867 and 1872 might refer to this taxon. It appears to have been a distinct species, with a thin, slim and low bill. As of 2009, the species had not been formally described.
