Pygmy Slow Lorises Are Born at Smithsonian’s National Zoo and Conservation Biology Institute

For the first time, the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) is celebrating the birth of two pygmy slow lorises, an endangered species. Small Mammal House keepers reported for duty the morning of March 21 and observed that 3-year-old mother Naga had given birth overnight and was caring for two infants. She and the babies’ 2-year-old father, Pabu, received a recommendation to breed from the Association of Zoos and Aquariums’ Species Survival Plan (SSP). These babies are the first offspring for both parents. Keepers have observed Naga carrying, grooming and nursing the babies, which appear to be healthy and strong. Animal care staff will determine the babies’ sexes at their first vet exam, which will take place in a few months. The family is on view at the Small Mammal House, and keepers say the babies are most active in the late morning and early afternoon.Naga and Pabu arrived at NZCBI in August 2022 from the Brookfield Zoo in Illinois and Little Rock Zoo in Arkansas, respectively. SSP scientists determine which animals to breed by considering their genetic makeup, health and temperament, among other factors. According to keepers, Naga’s personality is calm and sweet, though she tends to spook easily. She takes her time when exploring her exhibit and rests often. Pabu, on the other hand, seems to be more high energy. He is inquisitive and always the first to approach keepers and participate in training sessions and feedings. Although pygmy slow lorises reach sexual maturity around 9 months of age for females and 1.5 years of age for males, often they do not successfully reproduce until 2 to 3 years of age. Naga and Pabu’s “howdy” introductions took place in September 2023—about a year after they arrived—and the pair bred soon after meeting. This species’ gestation is about six months.

Litter of Five Cheetah Cubs Are Born at Smithsonian’s National Zoo

Carnivore keepers at the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) in Front Royal, Virginia, are celebrating a litter of five cheetah cubs born to 8-year-old adult female Echo Tuesday, Sept. 12. Viewers can enjoy watching the cubs grow via the Cheetah Cub Cam. Note that Echo may move her cubs out of the den and around her habitat so they may be out of view at times.

Animal care staff will leave Echo to bond with and care for her cubs without interference, but as opportunities arise, staff will perform quick health checks. During a recent weight check, staff confirmed there are three males and two females. The cubs appear to be strong, active, vocal and eating well.

Western Lowland Gorilla Born at the Smithsonian’s National Zoo and Conservation Biology Institute

For the first time in five years, primate staff at the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) are celebrating the birth of a western lowland gorilla—a critically endangered species. It was born between midnight and 6:15 a.m. on May 27 to 20-year-old mother Calaya and 31-year-old father Baraka. They bred in September 2022 following a breeding recommendation from the Association of Zoos and Aquariums’ Species Survival Plan (SSP). This is the second offspring for both parents.

Meerkats Are Born at Smithsonian’s National Zoo and Conservation Biology Institute

For the first time in 16 years, the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) in Washington, D.C., is celebrating the birth of three meerkats. Keepers in the Small Mammal House reported for duty the morning of May 10 and observed that 5-year-old Sadie had given birth overnight. NZCBI had received a recommendation from the Association of Zoos and Aquariums’ Species Survival Plan (SSP) to breed Sadie and the pups’ 6-year-old father Frankie. These pups are the first offspring for Sadie; Frankie sired offspring previously at his former zoo. Meerkats live in groups called mobs that can include as many as 30 individuals, although the average mob size is around 10 to 15 individuals. Visitors can view NZCBI’s meerkat mob—which also includes Sadie’s sister, Stella—at the Small Mammal House.

Andean Bear Cub Brothers Now on View Outdoors at the Smithsonian’s National Zoo

Just in time for spring break, two male Andean bear cubs named Sean and Ian are now on view at the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) in Washington, D.C. Over the past few weeks, the animal care team has worked with the brothers to prepare them for the transition. Cubs Ian and Sean began exploring the yard in mid-March alongside their mother, 4-year-old Brienne. For the past four months, members of the public have joined animal care staff in observing the cubs play and explore via a live Andean Bear Cub Cam and follow along with their growth through online “cubdates.”

Happy Birthday Kibibi!

Happy birthday, Kibibi! Smithsonian’s National Zoo and Conservation Biology Institute’s "little lady" celebrated her 14th birthday yesterday, January 10th, 2023. We’re turning back the clock with some archival footage highlights from herpast. First to 2009, the year of Kibibi’s birth. Then 2011, when 2-year-old- Kibibi received her first medical exam. And finally to 2020, when the staff dropped in on Kibibi’s husbandry training.

Look how far she’s come!

We can help western lowland gorillas like Kibibi by recycling. One of the metals inside electronic devices—tantalum—is mined from areas where gorillas live in the Democratic Republic of the Congo. We can protect their home—and reduce the need for more expansive coltan mining—by recycling our old electronics. Every small action has the potential to make a huge difference!

Andean Bear Cubs Born at Smithsonian’s National Zoo and Conservation Biology Institute

After an eight-year hiatus, the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) in Washington, D.C., is celebrating the birth of two Andean bears. The cubs were born Nov. 15 to first-time parents, 3-year-old mother Brienne and 9-year-old father Quito. The first cub was born around 4 p.m. and the second around 8:30 p.m. Animal care staff is closely monitoring the mother and cubs via the Andean Bear Cub Cam on the Zoo’s website, allowing Brienne to care for her offspring without interference. Virtual visitors can also observe the Andean bear family on this temporary platform until the cubs leave the den.
