The pudús (Mapudungun püdü or püdu, Spanish: pudú, Spanish pronunciation: [puˈðu]) are two species of South American deer from the genus Pudu, and are the world's smallest deer. The name is a loanword from Mapudungun, the language of the indigenous Mapuche people of southern Chile. The two species of pudús are the northern pudú (Pudu mephistophiles) from Colombia, Ecuador, and Peru, and the southern pudú (Pudu puda; sometimes incorrectly modified to Pudu pudu) from southern Chile and south-western Argentina. Pudús range in size from 32 to 44 centimeters (13 to 17 in) tall, and up to 85 centimeters (33 in) long. As of 2009, the southern pudu is classified as near threatened, while the northern pudu is classified as vulnerable in the IUCN Red List.
