Veterinary staff at the Smithsonian's National Zoo humanely euthanized a 19-year-old female Sumatran tiger, Soyono, this morning. A final pathology report may provide more information, but her health had been in decline for several weeks. In early October, Soyono—affectionately known as Soy—began to...
No Thanksgiving dinner is complete without a succulent roasted turkey. The U.S. Department of Agriculture estimates that consumers cook and eat more than 45 million turkeys every Thanksgiving. Very few Americans, however, know much about the difference between their gravy-smothered poultry and the...
Longtime followers of the tigers here at National Zoo are familiar with Soyono. She is our older female Sumatran tiger, and for years she and her mate Rokan formed our breeding pair. Soyono was born here in Washington in June of 1993 and has spent all of her long life here, becoming the oldest...
Smithsonian Conservation Biology Institute scientists and collaborators have found that the island scrub-jay's population on Santa Cruz Island—its only habitat—is significantly smaller than previously believed and that it is therefore at greater risk of extinction.
For clouded leopards, home is where the height is. After more than 30 years of studying clouded leopards, Zoo scientists have solved many puzzles about this perplexing species, starting with the biggest: figuring out just what a clouded leopard wants out of its habitat. It turns out that clouded...
ZooLights—powered by Pepco—at the Smithsonian's National Zoo is wilder than ever this year and a perfect holiday event for everyone in the family! The annual lights festival, hosted by Friends of the National Zoo, is 25 nights—longer than it has ever been in its six-year history—and it is free!
The newest additions at the Reptile Discovery Center at the Smithsonian's National Zoo were a surprise even to the keepers: eight tentacled snakes, born Oct. 21 to parents that have not produced viable young in the four years the Zoo has had them, despite breeding attempts. Tentacled snakes are...
Every year more than 4 million people enjoy the popular Appalachian Trail, which extends from Maine to Georgia and is surrounded by forests as well as agricultural and residential development. However, just as humans depend on the land, so, too, does the native wildlife. With the help of citizen...

Do you wonder what the world looks like from an animal's point of view? While visiting a zoo, have you ever looked at an object placed in an exhibit, a log or toy, for instance, and wondered why it was there? An exhibit's design is carefully and deliberately planned, not only to ensure the comfort...
Hurricane Sandy has come and gone here and the cats and keepers weathered the storm with no problems. On Sunday, the day before the rain started, we cleaned out gutters and drains, raked leaves, and placed sandbags at the doors. While we certainly got a lot of rain, it did not come all at once as it...
Coral reefs around the world are being impacted at an alarming rate. Globally, coral reefs face rising ocean temperatures and resulting ocean acidification. Locally, reefs face many other threats from tourism to building runoff, further compounding their degradation. In the very near future, many...
A team of scientists and keepers is traveling all over the eastern United States this year to study a unique and amazing animal: the hellbender. The hellbender ( Cryptobranchus alleganiesis) is a the largest salamander in North America, third largest in the world behind the Chinese and Japanese...
For 9 years we have monitored the small mammals and migratory birds in 12 areas, 6 of which were fenced to exclude deer. As the profile of under story characteristics changes, it may serve as an indicator for the potential of vertebrate species to live in these forests. Managing for deer may serve...
Last month, the Smithsonian's National Zoo celebrated the birth of its sprightly male dama gazelle calf, born Sept. 4 to mother Fahima.

Traditionally, biologists have gathered basic information such as population density and survival rates of carnivores by trapping, drugging, and fitting radiocollars on restrained animals. We are developing a new, noninvasive method that uses trained dogs to find scats (feces) of carnivores followed...
The Smithsonian-Mason School of Conservation, a unique program in terms of its academic offerings and contributions to the field of conservation, celebrated the completion of its expansive new academic facilities today, Oct. 18, at the Smithsonian Conservation Biology Institute in Front Royal, Va...
Last week, we bid a bittersweet farewell to Zuri and Fahari, as they left for their new home at the Santa Barbara Zoo. Their new keepers traveled to DC to meet the girls and accompanied them during their flight back to sunny California—via FedEx! Zuri and Fahari traveled in the same crates that...
