A Sumatran rhinoceros calf was born over the weekend at a sanctuary in Indonesia. The highly vocal and hairy animals are believed to be the closest living relatives to the wooly rhinoceros of the Ice Age — and there are only about 50 of the species left. Host Marco Werman speaks with Nina Fascione, executive director of the International Rhino Foundation, who says the calf born today speaks to the success of Indonesia’s conservation efforts.
