Winging It: A Parenting Test for Guam Kingfishers

In April, the Smithsonian Conservation Biology Institute celebrated the birth of two extinct-in-the-wild Guam kingfisher chicks. Find out more about the new chicks in this update from animal keeper Erica Royer.

How Do You Encourage Elephants to Build Positive Relationships?

The Zoo cares for five female Asian elephants from a few different family groups. Luckily, there are a few things that keepers can do to encourage them to build positive relationships. Learn more in this update from keeper Kayleigh Sullivan.

Clouded leopard cubs Jilian and Paitoon made their debut at the Smithsonian's National Zoo in September 2019.

Get a sneak peek into one very important aspect of clouded leopard cubs' daily care at the Zoo: training.

One of the common species Bird House keepers at the Smithsonian's National Zoo are working to better understand is the wood thrush — the official bird of Washington, D.C.

Continuing the Legacy of Bird Conservation

Raising awareness about the plight of migratory birds is key to their survival. The Smithsonian’s National Zoo and Conservation Biology Institute is in the midst of completely transforming its beloved Bird House from its humble foundation (circa 1928) into a celebration of birds and their amazing annual journeys. Since the Bird House closed to visitors in 2018, animal keepers, nutritionists and scientists have been working behind the scenes to better understand the husbandry of native songbirds and shorebirds.

Birds Connect Our World

As the sounds of traffic and crowds have hushed, you may have noticed more birdsong than usual. Stay-at-home measures keeping most of us indoors are likely emboldening our feathered friends, and many more humans are stopping to listen.

Some Egg-citing News and a Few Love Bites

There are only 135 Guam kingfishers in the world. The species is extinct in the wild, but scientists are working to change that by breeding the species for release in the near future.

Guam Kingfishers: A Truly Rare Breed

As an animal keeper at SCBI, some of my favorite birds to work with are small but sassy. Guam kingfishers certainly fall into this category. We have three pairs to introduce during this year's breeding season, so we have our work cut out for us.

Preparing for Cheetah Cubs

At the Smithsonian Conservation Biology Institute in Front Royal, Virginia, the carnivore team is gearing up for a very special arrival: cheetah cubs! As one of 10 facilities in the Cheetah Breeding Center Coalition, SCBI researchers study the behavior, biology, health and reproduction of these rare cats.

Learning More About Panda Health One Drop of Blood at a Time

You may not like needles or giving blood when you go to the doctor’s office, but did you know that blood is an important diagnostic tool for veterinarians? When an animal is feeling sick, one of the very first steps a veterinarian takes is to obtain a blood sample for analysis.

Get an insider's look at how animal keepers at the Smithsonian's National Zoo use activities, food, training and toys to safely care for 850-pound Grevy's zebra Moyo.

The Smithsonian Conservation Biology Institute's Persian onagers and their foals enjoyed 6 inches of snow in January.

Persian Onagers Dig the Snow

It has been a fairly mild winter at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, with the exception of a pretty big snowfall Jan. 7. It was the first snow day for SCBI's newest Persian onager foals, but there are no snow days for the animal keepers who care for these ungulates.

Under (Blood) Pressure: Monitoring Heart Rates in Zoo Primates

How do you get an orangutan to sit still for an electrocardiogram? All it takes is a little patience and a lot of ingenuity! The Smithsonian’s National Zoo’s positive reinforcement training program enables primates to voluntarily participate in their own medical care without the need for anesthesia.

Making Sense of Animal Milks

You might be surprised to see someone walking around the Smithsonian’s National Zoo in a full-body snowsuit, but nutrition laboratory research assistant Jenna Pastel wears a snowsuit year-round. She spends her days in a -20 degree freezer that is home to the world's largest animal milk repository.

Conserving the Last of Guam’s Avifauna: The Recovery of the Guam Rail

Walking through the forests of Guam is arresting — because it’s silent. But the sound of the forest is returning.

2019's Conservation Stories Worth Celebrating

Saving species is what we strive to do every day at the Smithsonian’s National Zoo and Conservation Biology Institute. As the year winds down, we’re reflecting on some of our biggest conservation success stories of 2019.

Black-footed ferrets are well-suited for their prairie environment, where their colors help them blend in with grassland soils and plants.

What Sound Does a Black-footed Ferret Make? And Other Ferret Facts

We’ve ferreted out the answers to some of the most-searched questions about North America’s only native ferret species.

Not All Birds Fly South for the Winter

Researchers in Virginia wanted to learn how common field management practices — like mowing, burning or animal grazing — affect birds that stay for the winter. They turned to local farmers and landowners for help.

Forty years ago, the distinctive call of the bobwhite quail could be heard throughout Virginia’s grasslands. Today, their calls are fading.

Answering the Call for Bobwhite Quail

Forty years ago, the distinctive call of the bobwhite quail could be heard throughout Virginia’s grasslands. Today, their calls are fading — silenced by changing farm practices and land development that have led to the quail’s steep population declines. The Smithsonian Conservation Biology Institute’s Virginia Working Landscapes program has joined a nationwide effort to save this charismatic species and its habitat.

Long-billed curlews are the largest shorebirds in North America, but they are only found along coasts during the winter. They spend their summers breeding in the grasslands of Montana.

Hiding in Plain Sight: Tracking the Long-billed Curlew

Long-billed curlew are shorebirds that spend their summers breeding in the grasslands of Montana. Smithsonian ecologists are equipping them with GPS trackers to learn more about their movements.

Smithsonian Conservation Biology Institute scientist Mike Henley dives at a coral nursery where brown rice coral and blue rice coral grow.

Testing the Waters: Coral Nurseries and Climate Change

What makes (or breaks) a coral’s ability to survive rising sea temperatures? It’s a puzzling predicament, and scientists are hoping coral nurseries can help crack the code. To test the waters, they grow brown rice coral and blue rice coral in various temperatures and conditions, then reintroduce fragments into the ocean. Suspended from a “tree” above the sea floor, these corals are teaching Smithsonian Conservation Biology Institute scientist Mike Henley whether corals grown in warmer waters fare better than their cold-water counterparts.
