BRONX, N.Y. — May 22, 2026 — The Wildlife Conservation Society’s Bronx Zoo is announcing the birth of twin collared lemurs in a rare event for the Endangered species.

The collared lemur is a medium-sized primate native to southeastern Madagascar. They are considered Endangered by the IUCN Red List of Threatened Species, as populations have declined by 50% in the past 24 years due primarily to habitat loss and poaching. Collared lemurs belong to the most endangered group of mammals in the world; roughly 96% of lemur species are at risk of extinction.

Less than 25% of all collared lemur pregnancies in managed care settings result in multiple births, making this pair’s birth an especially hopeful moment for the conservation of the species. The Bronx Zoo participates in the Collared Lemur Species Survival Plan (SSP), an AZA-managed breeding program that helps maintain the species’ genetic viability. Bronx Zoo animal care staff will determine the sex of each infant at their first veterinary exam.

Collared lemurs are named for the distinctive rust-colored fur around their necks. Infants typically nestle into their mother’s belly for nursing and warmth and can be seen riding on her back as they grow. Adults spend most of their lives in treetops, utilizing their long tails to balance as they leap through the forest canopy.

This pair can now be seen at the Spiny Forest section of the Bronx Zoo’s Madagascar! habitat. While visiting, guests can also encounter a variety of species that reflect the extraordinary biodiversity that WCS works to protect across Madagascar – including Critically Endangered red-ruffed lemurs, radiated tortoises, among others.
