The Dodo has been depicted with a naked head.
 While there has been an effort since the mid-19 century to list all historical illustrations of dodos, previously unknown depictions continue to be discovered occasionally
The Latin name cucullatus ("hooded") was first used by Juan Eusebio Nieremberg in 1635 as Cygnus cucullatus, in reference to Carolus Clusius's 1605 depiction of a dodo
