Chilean Pudu (scientific name: Pudu puda) is called Southern Pudu in foreign language. It is the smallest deer in the world and has no subspecies.
Chilean Pudu is a diurnal animal, but it is more active in the afternoon, evening and morning. It will go to open places to forage. The food is leaves, branches, bark, buds, fruits and seeds. Due to its small size, it often has to stand on its hind legs or jump onto fallen tree trunks to reach higher vegetation. It mainly feeds on the understory plants of moist forests, including ferns and leaves. Because its food is full of water, it rarely drinks water. This species has well-trampled trails throughout the year, with a feeding range of 1,626 hectares, and the habitat and rest areas are connected by paths through dense vegetation. Dung piles are usually formed next to these trails. They defecate in the same place and pile up dung piles, which may be used to mark territory.
The short but strong legs of the Chilean balearic deer allow them to walk on steep rocky slopes as if they were flat ground. When threatened, they will flee in a zigzag shape. Natural enemies include pumas, foxes, small cats and eagles.
Chilean deer are solitary animals that only gather during the breeding season, usually in April and May. The female's gestation period is usually from November to January each year, and a fawn will be born after about 7 months. The fawn is weaned at 2 months, and females reach sexual maturity at 3-6 months and males at 8-12. The offspring can remain with their mother for 8-12 months before becoming independent.
The population of the Chilean deer is declining due to habitat destruction caused by overgrazing and human development. The main threat to the Chilean deer is the destruction of temperate forest habitats throughout Chile, which are used for cattle ranching, logging and other human development. Habitat fragmentation and destruction through the conversion of forests to open land and exotic tree plantations has caused serious problems for the survival of the Chilean deer. Road traffic accidents and hunting are also responsible for the decline in populations. Hunters use hunting dogs to hunt wild Chilean deer. Other threats include the introduction of exotic species, such as red deer from Europe, which compete with the Chilean deer for food. Domestic dogs may also prey on the deer and may spread parasites, to which the Chilean deer are particularly susceptible.
