One of the Bronx Zoo’s storks was on duty last month–it delivered an adorable endangered pygmy slow loris! Though the baby was born back on December 13, 2025, the Zoo just announced its birth today, January 22, 2026.
The pygmy slow loris is a small primate native to Southeast Asia. They’re born fully furred with their eyes open and reach an adult weight of just about one pound. Impossibly cute, we know. Infants are carried on the mother’s stomach and intermittently “parked” on branches while the mother forages for food.
As the baby grows, it’ll become more active and independent, becoming fully weaned around 6 months of age. As of now the baby’s sex is unknown, though it’ll be determined at its first veterinary exam.
Sadly, due to habitat loss and poaching for the illegal pet trade, the pygmy slow loris is considered endangered by the IUCN Red List of Threatened Species–that’s where the Bronx Zoo’s conservation efforts step in.
Being the Zoo is world-renowned for its leadership in the areas of animal welfare, husbandry, veterinary care, education, science, and conservation, it participates in the pygmy slow loris Species Survival Plan (SSP), a breeding program managed by the Association of Zoos and Aquariums (AZA) to maintain a genetically diverse population of the endangered species.
The baby pygmy slow loris marks the first primate born at the zoo’s new immersive World of Darkness exhibit, which re-opened to the public after 16 years in July 2025. The exhibit brings the mysteries of nocturnal life into the spotlight with 25 species and 21 habitats, and it puts visitors right in the center of it all!
Beyond the pygmy slow loris, other species featured within exhibit include:
- Nancy Ma’s Douroucouli (Aotus nancymaae)
- Hoffmann’s Two-toed Sloth (Choloepus hoffmanni)
- Northern Luzon Giant Cloud Rat (Phloeomys pallidus)
- Emperor Scorpion (Pandinus imperator)
- Gray Mouse Lemur (Microcebus murinus)
- Blood Python (Python brongersmai)
- Common Vampire Bat (Desmodus rotundus)
- Fat-tailed Dwarf Lemur (Cheirogaleus medius)
- Naked Mole Rat (Heterocephalus glaber)
Though the pygmy slow loris is certainly photogenic–we mean, come on, just look at that face!–the species is sensitive to light. Thus, the Bronx Zoo kindly requests that visitors resist taking disruptive flash photographs.
