The pudus are a unique group of small deer found in South America. They belong to the genus Pudu and are recognized as the world's smallest deer species.

While chevrotains are even smaller, they are not true deer and belong to a different family. The name "pudú" is a loanword from Mapudungun, the language of the indigenous Mapuche people. These animals are vital to the ecosystems of the Andes Mountains. Because they live on these slopes, they are sometimes called the "Chilean mountain goat."

There are two distinct species within the Pudu genus. The northern pudu, known scientifically as Pudu mephistophiles, lives in the northern Andes. This species inhabits parts of Venezuela, Colombia, Ecuador, and Peru at elevations above 1,000 meters. The southern pudu, or Pudu puda, lives in southern Chile and south-western Argentina.

The southern species can be found from sea level up to 2,500 meters. The southern pudu is currently classified as near threatened on the IUCN Red List. Meanwhile, the northern pudu is listed as Data Deficient, meaning scientists do not have enough information to determine its status.

Physically, the pudus have very specific traits that help them navigate dense forests. The southern pudu is slightly larger than the northern species. It has a stocky frame supported by short, slender legs.

These deer can weigh up to 13.5 kilograms, though the highest recorded weight is 15 kilograms. They have small black eyes, black noses, and rounded ears. A notable feature is sexual dimorphism, which means males and females look different. Males possess short, spiked antlers that are not forked and are shed annually. Females do not have antlers at all.

They also have large preorbital glands on their heads for scent communication.

These deer are highly specialized herbivores that live in temperate rainforests. They eat a variety of plants, including vines, leaves, shrubs, ferns, and tree bark.

Because their diet of succulent foliage contains high water content, they can survive for long periods without drinking. Their small size requires them to use clever methods to reach food. They may stand on their hind legs to reach higher branches. They also climb tree stumps or bend bamboo shoots horizontally to access leaves. Mature males may even use their spiked antlers to peel bark from saplings.

In the wild, pudus are solitary and crepuscular animals. This means they are most active during the morning, late afternoon, and evening.

Each individual maintains its own home range, or territory. They mark these areas with large dung piles near resting or eating spots. Because they are easily frightened, they may bark when they feel fear. If they are pursued by predators like the cougar or Andean fox, they run in a zigzag path. This movement helps them escape through the thick underbrush of their habitat. In the wild, they typically live between 8 and 10 years.

Reproduction for the pudu follows a specific seasonal cycle in the Southern Hemisphere. The mating season occurs during the autumn, from April to May.

After mating, the gestation period—the time the offspring grows inside the mother—lasts between 202 and 223 days. Most offspring are born during the austral spring between November and January. A single fawn is usually born, though twins can occur. Newborns are quite small, typically weighing between 250 and 450 grams.

While they are fully grown in three months, they may stay with their mothers for up to a year.

Conservation efforts are working to protect these small deer from extinction. The southern pudu faces threats from habitat loss due to logging, agriculture, and cattle ranching.

They also face dangers from road accidents and illegal hunting. To help, an international captive-breeding program led by the Universidad de Concepcion has been established. Some deer have been successfully reintroduced into Nahuel Huapi National Park in Argentina using radio collars for tracking. These efforts aim to ensure that the pudu continues to thrive in its native South American forests.
