Jozi and the new baby’s father, King, are part of the critically endangered eastern subspecies of black rhinoceros, making the new baby a significant event not just for the Oregon Zoo but for the entire species.

According to zoo officials, 11-year-old eastern black rhino Jozi gave birth to a healthy 100-pound baby. It was announced mid-November that both Jozi as well as the zoo’s elephant Rose-tu were pregnant with babies expected by January at the latest.
