Orphaned elephant calves from the Reteti Elephant Sanctuary are being translocated to their new home in Sera Wildlife Conservancy, in Kenya’s Samburu County this week.

Last month, after days of anticipation, Mabel, a 4-year-old pygmy hippopotamus at the San Diego Zoo, gave birth to her first calf.

At a quiet, off-view area at the San Diego Zoo Safari Park, wildlife care staff are celebrating a momentous milestone—the hatching of an endangered lappet-faced vulture chick.

Scientists at San Diego Zoo Global’s Frozen Zoo® have achieved a major milestone in saving wildlife species: This unique collection of genetic material now contains 10,000 individual cell lines from more than 1,100 species and subspecies—some of them critically endangered.
