Since her birth in early February, the calf has been growing and beginning to bond with her care team and herd. She will go on view in-person and online starting April 22

Adult emperor penguins have waterproof feathers. But they replace all of them every year during their catastrophic molt, which makes them vulnerable.

As Their Antarctic Habitat Melts Away, Emperor Penguins Are Now Considered an Endangered Species

The International Union for Conservation of Nature predicts that the birds’ population could be cut in half by the 2080s. The organization also changed the statuses of Antarctic fur seals and southern elephant seals
