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...

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...

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 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...

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...

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...

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...
