The pudu deer, specifically the Southern pudu (Pudu puda), is the world’s smallest deer species, native to the temperate rainforests of southern Chile and southwestern Argentina. Adult Southern pudus stand about 32 to 44 centimeters (13 to 17 inches) tall at the shoulder and weigh between 6.4 to 13.6 kilograms (14 to 30 pounds). Known for their small size and shy nature, pudus are elusive creatures that prefer dense underbrush where they feed on leaves, bark, and fallen fruit. Despite their diminutive size, pudus are excellent climbers and jumpers, which helps them navigate their forested habitats.
