Dr. Pierre Comizzoli is a reproductive cryobiologist at the Smithsonian Conservation Biology Institute. In this giant panda update he explains how the Zoo stores semen for endagered wildlife, which can be used for procedures like an artificial insemination. The team of people at the Zoo who study...

As we continue our Elephant Trails photo blog series, our next stop is their house. These photos of Elephant Trails would not be complete without a view of our elephant's indoor living areas. A camera and ladder are helping us to capture every area from an elephant's point of view. Since Shanthi...

Figuring out the sex of a porcupine can be a difficult task. They aren't always easy to handle, and when they are young they show no sexual dimorphism. But veterinarians, geneticists, and keepers at the Smithsonian's National Zoo have figured out a novel and easy way to determine the sex of...

Well the bad news is that Damai was not pregnant as a result of the single breeding during her last heat. The good news is Kavi and Damai have really improved their skill set when it comes to procreation! We had been keeping our fingers crossed after their last attempt but were not too disappointed...

The eight-week-old Andean bear cubs at the Smithsonian's National Zoo's received a clean bill of health today from the Zoo veterinarians.

Over the next few months we'll be bringing you giant panda updates that will focus on Mei Xiang and Tian Tian, and the research Zoo scientists conduct related to giant pandas around the world. You'll be hearing from many different experts at the Zoo and the Smithsonian Conservation Biology Institute...

Are bird bills simply for eating or do they play a role in mating?

We're so glad you're enjoying watching our bear cub cams, both Andean and sloth! We're thrilled to be able to share this experience with you. Very few people have ever gotten to observe maternal behavior and cub development in these early weeks and months in the den, so this experience is as...

It's clear from watching the Sloth Bear Cam that this little cub has a lot of personality—just like Hana! It's not unusual to see the two playing: she will roll on her back and hug the cub, paw at him/her, and exhibit a "play face" (her mouth is open and her lower lip is loose rather than taut). At...

The Gorilla Species Survival Plan (SSP) is dedicated to providing a healthy, genetically diverse and self-sustaining population of Western Lowland gorillas in zoos across the United States. One goal of the Gorilla SSP is to maintain gorillas in species typical groupings, either as a troop consisting...

Hana and the cub continue to do well! Keepers are seeing the cub sit up more but it still hasn't tried to climb onto Hana's back. Hana leaves the den more frequently and eats small snacks on a daily basis, but she still spends the majority of her time in the den with the cub. We occasionally see...

Mei Xiang's den has been transformed for the new breeding season! Observant panda cam viewers have no doubt seen the difference in the configuration of the barred barriers. By shifting the angle of the bars, keepers will be able to have more direct access to Mei Xiang and future cub(s) while they...

When great ape keepers at the Smithsonian's National Zoo were deciding how to add more variety and enrichment to their animals' lives, they turned to Orangutan Outreach and a program that had seen great success in 12 other zoos around the world: Apps for Apes. With the tap of a finger, keepers are...

Time flies: Our sloth bear cub is one month old today! Hana continues to be very attentive to him or her, and keepers are still monitoring the pair closely through their closed-circuit cam. Because the cub's dark hair is growing quickly, it's getting tougher to spot. (If it turns just so, the white...

One of the biggest questions scientists at the Smithsonian Conservation Biology Institute (SCBI) were working hand-in-hand with their colleagues in China to understand in the late 1990s was: why are pandas 'challenged' at reproducing? Almost a decade later, scientists are still answering questions...

Things in the lion house have been fairly quiet this winter. When temps drop to freezing, we usually let the lions decide where they want to play throughout the day. With the colder air moving into DC this January, the lions have been choosing to hang-out inside for much of the day. We do have a few...
