The 'Pudú', the smallest known deer in the world, lives on which continent?

The pudús 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 and south-western Argentina. The two species of pudús are the northern pudú from Venezuela, Colombia, Ecuador, and Peru, and the southern pudú from southern Chile and south-western Argentina.

The southern pudú is the better-known species. It is slightly larger than its sister species, the northern pudú, being 35 to 45 cm (14 to 18 in) tall at the shoulder and weighs 6.4 to 13.4 kg (14 to 30 lb). The antlers of the southern pudú grow to be 5.3 to 9 cm (2.1 to 3.5 in) long and tend to curve back, somewhat like a mountain goat. Its coat is a dark chestnut-brown, and tends to tuft in the front, covering the antlers. It is found at lower elevations than its sister species, from sea level to 2,000 m (6,600 ft).

The northern pudú is the smallest species of deer in the world, being 32 to 35 cm (13 to 14 in) tall at the shoulder and weighs 3.3 to 6 kg (7.3 to 13.2 lb). The antlers of the northern pudú grow to about 6 cm (2.4 in) long, also curving backward. Its coat tends to be lighter than that of the southern pudú, but the face is darker compared to the coat. It is found at higher altitudes than its sister species, from 2,000 to 4,000 m (6,600 to 13,100 ft) above sea level.
