As part of the celebration, we’re asking for help naming two of our scimitar-horned oryx calves at the Smithsonian Conservation Biology Institute in Front Royal, Virginia. The calves were born in...
Beginning Aug. 18, the David M. Rubenstein Family Giant Panda Habitat will be partially closed to keep a quiet area around panda Mei Xiang’s den. Although we are not able to confirm if she is pregnant, Mei Xiang is exhibiting expected, normal behaviors following a secondary hormone rise that are in...
The Giant Panda Habitat will be partially closed to keep a quiet area around female giant panda Mei Xiang’s den. Although keepers are not able to confirm if she is pregnant, Mei Xiang is exhibiting expected, normal behaviors after the secondary hormone rise that are in line with both a pregnancy and...
Veterinarians are giving Mei Xiang weekly ultrasounds to track changes in her uterus. Though it's too early to see a possible cub on an ultrasound, SCBI scientists detected a rise in hormones, indicating Mei Xiang will either give birth or experience the end of a pseudopregnancy in 30 to 50 days.
An endangered brown kiwi chick kicked her way out of her egg at the Smithsonian Conservation Biology Institute (SCBI) in Front Royal, Virginia, between Saturday, July 29, and Sunday, July 30.
All across the world, scientists are tracking the movements of animals, collecting considerable data to better understand how animals migrate, what paths they take and what threats they may face along the way. A new statistical model from the Smithsonian Conservation Biology Institute (SCBI) and...
For Asian elephant keepers, working among the giants of the animal kingdom entails training, enriching and caring for the Zoo's multi-generational herd, as well as contributing to research and educating visitors about the conservation of this endangered species.
Behavior can tell the giant panda team quite a bit about the pandas, but the behaviors they exhibit are only half the story. When it comes to predicting when Mei Xiang will give birth, or when she is in the final stages of a pseudopregnancy, scientists rely on a few different factors. They monitor...
