Sabi is the fourth calf from mother Bakhita and has two older brothers and a sister.

At just seven weeks old, Sabi weighs 111.5 kilograms and is already a crowd favourite following her public debut last week.

Black rhino keeper Hayley Brooks said zoo keepers were happy to have welcomed a female calf as males had been more common.

Black rhinos are also currently listed as critically endangered with estimates of less than 6000 remaining worldwide.

Miss Brooks said another reason for Sabi Star having been such a beacon of light for the zoo was that she comes following the hardships of the harsh and long-lasting drought.

"Us keepers all submitted names which all had an African origin or a nice meaning behind them that we liked and then we put those to the team and voted on them and Sabi Star was voted for the most," Miss Brooks said.

"Her name actually comes from a flower which is native to Zimbabwe, which flowers after times of really harsh drought, so we thought that was quite fitting."

Taronga Western Plains Zoo is internationally renowned for its black rhino conservation breeding program and actively funds and supports conservation efforts for rhinos in Africa, Indonesia and India.
