In early November 2024, a rare pudu fawn was born at an Argentine biopark, giving scientists and conservationists a valuable chance to learn more about this tiny and elusive deer species. The male fawn, weighing only 1.21 kg (2.7 lbs), was named Lenga after a tree found in the Andean Patagonian forest. Pudus are one of the world’s smallest deer, growing up to 50 cm (20 inches) tall and weighing up to 12 kg (26.5 lbs). Lenga’s birth has brought attention to the pudu’s fragile situation, as fewer than 10,000 are left in the wild. The International Union for Conservation of Nature (IUCN) lists them as near-threatened due to dangers from wild dogs and other introduced predators.

Lenga’s arrival offers hope for the pudu’s conservation. Researchers can now gather important data on the species. For the first few months, Lenga will stay with its mother, Chalten, and father, Nicolino, feeding on its mother’s milk before switching to a herbivorous diet. The white spots on its fur provide natural camouflage, helping protect it from predators during both day and night. The Temaiken Foundation, which oversees the biopark, believes studying Lenga will enhance knowledge of pudu behavior and improve conservation strategies for this species and others in Patagonia, like the huemul. This birth is a vital step in preventing the pudu’s extinction.
