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.

Two lactating African elephants—Umngani (pronounced OOM-gah-nee), who gave birth to a healthy female calf, Mkhaya or “Kaia”, on Sept. 26, 2018; and Ndulamitsi, known as Ndula, who gave birth to a healthy male calf, Umzuli-Zuli or “Zuli,” on Aug. 12, 2018—are participating in a nutritional study, allowing researchers to study the content of their milk.
