Surveys have been conducted at Hubbard Brook since 1999 to better understand how birds respond to a changing environment.

Born in Sri Lanka around 1975, Asian elephant Shanthi developed arthritis in her front-left leg more than a decade ago. While there is no cure for arthritis, there are ways to alleviate the symptoms, and our animal care experts have focused on her comfort. We'll be posting the latest information on...

Bird House keepers at the Smithsonian's National Zoo are celebrating the arrival of a Stanley crane chick, hatched July 10 to the Zoo's 27-year-old female and 17-year-old male. Animal care staff are monitoring the chick closely and report that it appears to be alert and strong, and the parents are...

What affects an elephant’s ability to get pregnant? Scientists from the Smithsonian Conservation Biology Institute (SCBI) set out to solve that mystery. With help from peers across North American zoos, they evaluated elephant hormones to learn how body weight, socialization and life events affected...

Nearly one-third of all amphibian species globally are at risk of going extinct. While the global amphibian crisis is the result of habitat loss, climate change and pollution, the deadly amphibian chytrid fungus plays a large role in the frogs' disappearances. In the fight for frogs, Smithsonian...

What happens when a species is restored to its rightful place in the wild? In the case of the scimitar-horned oryx, the answer to that question has been nearly 30 years in the making. Next month, 25 oryx will be released to a large reserve in Chad, a country where they have been extinct in the wild...

When it comes to choosing a location for a natural gas marine terminal, PERU LNG (Liquefied Natural Gas) discovered that the options are not always black and white. When their construction site became the home of choice for Humboldt penguins, PERU LNG called upon the Smithsonian Conservation Biology...

For the first time, the Smithsonian Conservation Biology Institute (SCBI)'s kiwi pair are parents! Keeper Wesley Bailey reveals how a strict diet helped dad Ngati Hine Tahi get in shape and resulted in the pair's first chick. This story appears in the July 2016 issue of Smithsonian Conservation...

Smithsonian's National Zoo scientists are all over the globe and, most recently, at the peaks of Machu Picchu, Peru! Andean bear curator Craig Saffoe, chief veterinarian Don Neiffer, and Smithsonian Conservation Biology Institute scientist Francisco Dallmeier trekked to South America to share...

For nearly 50 years, Smithsonian Conservation Biology Institute primatologist Wolfgang Dittus has studied and lived among the toque macaques in Sri Lanka. In our Q & A, he reveals how family relationships, intelligent behavioral strategies and a healthy environment are key to this species’ survival...

As their native habitat continues to shrink, wild cheetahs are facing a drought of genetic diversity. This is in direct contrast with the population of cheetahs in zoos, which is as genetically diverse as it was 30 years ago because of cooperative and strategically managed breeding programs. The...

Smithsonian Conservation Biology Institute (SCBI) scientists are working furiously to beat the bleaching clock and cryopreserve coral. But, they’ve run into a wall: bleaching is causing coral to produce poor-quality sperm and eggs. In turn, less are able to settle or survive the cryopreservation...

For the first time in 32 years, the Smithsonian's National Zoo's American Trail team celebrated the arrival of a sea lion pup, born June 26 to 11-year-old mother Calli.

The planet's last stronghold of wild cheetahs (Acinonyx jubatus) is losing genetic diversity at an alarming rate according to a new study from the Smithsonian Conservation Biology Institute (SCBI) and partners published June 21 in the journal Biological Conservation. This is in direct contrast with...

Not even pioneering assisted-reproduction techniques can bolster the odds of successful reproduction in bleached coral reefs, according to a new study from the Smithsonian Conservation Biology Institute (SCBI) and the University of Hawaii. The findings, which were published June 17, in Reproduction...

The National Zoo's senior male sloth bear, 25-year-old Francois, was humanely euthanized yesterday. In human care, sloth bears typically have a median life expectancy of early-to-mid 20s. A final pathology report will provide more information in the coming weeks. Animal care staff had kept a close...

For the first time in 25 years, staff at the Smithsonian's National Zoo are making preparations for the highly anticipated birth of an endangered Bornean orangutan. With a breeding recommendation from the Association of Zoos and Aquariums' Species Survival Plan (SSP), the 19-year-old parents to be...

Virtual visitors to the Smithsonian's National Zoo will now be able to see its herd of six Asian elephants up-close. The Zoo's high-definition elephant cam was previously stationary and only showed the elephants when they walked in view of the cameras in the Elephant Community Center. The upgraded...
