Great Sumatran rhino news! Harapan is a dad! In 2015, we made the very tough decision to send the third Cincinnati Zoo-born Sumatran rhino calf, Harapan, to Indonesia so that he would have the opportunity to contribute to his critically endangered species’ survival. On Saturday, November 25, 2023, a healthy male calf, sired by Harapan, was born!
