“Knowing Umngani’s birth window was between Sept. 12 and Oct. 18, we had been placing her in a small area of the yard at night, separate from the rest of the herd,” Curtis Lehman, animal care supervisor at the Safari Park, said in a statement. “She has given birth three other times, and those calves arrived late—so when we checked on her first thing this morning, we were surprised and thrilled to see her caring for her healthy newborn. Umngani is a great mom, and she and the baby are doing very well.”
