The pudus (Mapudungun püdü or püdu,[4] Spanish: pudú, Spanish pronunciation: [puˈðu]) are two species of South American deer from the genus Pudu, and are the world's smallest deer.[5] The chevrotains (mouse-deer; Tragulidae) are smaller, but they are not true deer. The name is a loanword from Mapudungun, the language of the indigenous Mapuche people of central Chile and south-western Argentina.[6]
