Growing Up Guam Kingfisher

Breeding season is the most demanding time of year for the bird team at the Smithsonian Conservation Biology Institute, but it can also be the most rewarding. With fewer than 140 Guam kingfishers left in the world, every egg laid and chick hatched is a step closer to saving this species.

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.

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.

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.

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.

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.

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.

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.

As far as predators go, coyotes are one of the most resourceful and resilient.

Connecting with Coyotes on the Prowl

In Virginia’s Shenandoah Valley, eastern coyotes join the ranks of top predators, along with black bears and foxes. Still, these clever canines face threats in their native habitat. Their daily migrations take them over roads and private lands, where the likelihood of human-animal conflict is high. Using GPS collars, Smithsonian Conservation Biology Institute scientists, led by biologist Joe Guthrie, are about to embark on a study to piece together the movements of coyotes on the prowl.

Studying Animals in Extreme Landscapes

We know that animals select where to live based on their needs — such as food, shelter or safe passage — and their preferences change throughout the year. I want to understand why large mammals choose some areas over others, and how human interaction affects their activity and distribution.
