The pudús ([7] As of 2009, both species are classified as "Endangered" in the IUCN Red List.[8][9]


The genus Pudu was first erected by English naturalist John Edward Gray in 1850. Pudua was a Latinized version of the name proposed by Alfred Henry Garrod in 1877, but was ruled invalid. Pudús are classified in the New World deer subfamily Capreolinae within the deer family Cervidae. The term "pudú" itself is derived from the Mapuche people of southern Chile.[3] Because they live on the slopes of the Andes Mountain Range, they are also known as the "Chilean mountain goat".[10]

Two similar species of pudús are recognised:

  • The southern pudú (P. puda) is the better-known species found in the southern Andes of Chile and Argentina. 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).[11] 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.[12] It is found at lower elevations than its sister species, from sea level to 2,000 m (6,600 ft).
  • The northern pudú (P. mephistophiles), found in the Andes of Colombia, Peru, and Ecuador, 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).[11] 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.[11] 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.


The pudús are the world's smallest deer, with the southern pudú being slightly larger than the northern pudú.[2] It has a stocky frame supported by four short and slender legs. It is 32 to 44 cm (13 to 17 in) high at the shoulder and up to 85 cm (33 in) in length. Pudús normally weigh up to 12 kg (26 lb),[7] but the highest recorded weight of a pudú is 13.4 kg (30 lb).[3] Pudús have small, black eyes,[2] black noses, and rounded ears with lengths of 7.5 to 8 cm (3.0 to 3.1 in).

Habitat and distribution

The pudú inhabits [7] The northern pudú is found in the northern Andes of Colombia, Ecuador, and Peru, from 2,000 to 4,000 m (6,600 to 13,100 ft) above sea level. The southern species is found in the slope of the southern Andes from sea level to 2,000 m (6,600 ft).

The climate of the pudú's habitat is composed of two main seasons: a damp, moderate winter and an arid summer. Annual precipitation in these areas of Argentina and Chile ranges from 2 to 4 m (6.6 to 13.1 ft).[16]



The pudú is a solitary animal whose behavior in the wild is largely unknown because of its secretive nature.[17] Pudús are crepuscular, most active in the morning, late afternoon, and evening. Their home range generally extends about 16 to 25 ha (40 to 62 acres), much of which consists of crisscrossing pudú-trodden paths. Each pudú has its own home range, or territory.[16] A single animal's territory is marked with sizable dung piles found on paths and near eating and resting areas. Large facial glands for scent communication allow correspondence with other pudú deer.[13] Pudús do not interact socially, other than to mate.[16] An easily frightened animal, the deer barks when in fear.[10][18] Its fur bristles and the pudú shivers when angered.[10]

Predators of the pudús include the horned owl, Andean fox, Magellan fox, cougar, and other small cats. The pudú is a wary animal that moves slowly and stops often, smelling the air for scents of predators. Being a proficient climber, jumper, and sprinter, the deer flees in a zigzag path when being pursued.[19] The lifespan of the pudús ranges from 8 to 10 years in the wild.[18] The longest recorded lifespan is 15 years and 9 months. However, such longevity is rare and most pudús die at a much younger age, from a wide range of causes. Maternal neglect of newborns, as well as a wide range of diseases, can decrease the population.[3] A popular rumor is that if alarmed to a high degree, pudús die from fear-induced cardiac complications.[10]


The pudús are herbivorous,[10] consuming vines, leaves from low trees, shrubs, succulent sprouts, herbs, ferns, blossoms, buds, tree bark, and fallen fruit.[16][20][21] They can survive without drinking water for long periods due to the high water content of the succulent foliage in their diets.[2]

Pudús have various methods of obtaining the foliage they need. Their small stature and cautious nature create obstacles in attaining food.[21] They stop often while searching for food to stand on their hind legs and smell the wind, detecting food scents.[16][19] Females and fawns peel bark from saplings using their teeth, but mature males may use their spikelike antlers. The deer may use their front legs to press down on saplings until they snap or become low enough to the ground so they can reach the leaves. Forced to stand on their hind legs due to their small size, the deer climb branches and tree stumps to reach higher foliage.[13] They bend bamboo shoots horizontally in order to walk on them and eat from higher branches.[16]

Pudús are solitary and only come together for [7] Young are weaned after 2 months. Females mature sexually in 6 months, while males mature in 8–12 months.[13] Fawns are fully grown in 3 months, but may stay with their mothers for 8 to 12 months.[15]

Status and conservation

As of 2009, both species of pudús are classified as "Endangered" on the [7] Pudús are protected in various national parks; parks require resources to enforce protection of the deer.[15]

Efforts to preserve the pudú species are being taken in order to prevent extinction. An international captive-breeding program for the southern pudú led by Concepcion University in Chile has been started.[13][25] Some deer have been bred in captivity and reintroduced into [7] Reintroduction efforts include the use of radio collars for tracking.[26] The Convention on International Trade in Endangered Species has banned the international trading of pudús.[15] The Wildlife Conservation Society protects their natural habitat and works to recreate it for pudús in captivity.[19] Despite efforts made by the World Wildlife Fund, the size of the pudú population remains unknown.[16] Threats to the pudús remain despite various conservation efforts.[15]


Pudús are threatened due to the [7][15] They are overhunted and killed for food by specially trained hunting dogs.[2][15][26] The recently introduced red deer compete with pudús for food. Domestic dogs prey upon pudús and transfer parasites through contact. Pudús are very susceptible to diseases such as bladder worms, lungworms, roundworms, and heartworms.[15][19]
