BUFFALO, N.Y. — The Buffalo Zoo announced another new addition to their family.

Tashi, the one-horned rhino, gave birth to a 123.5 lbs. male calf recently.

Tashi was pregnant for 488 days!  Mom and baby are bonding and doing well. 

This is the third successful birth of a greater one-horned rhino via artificial insemination.   Tashi's third calf, Monica, was the first and a second rhino was born recently at the Zoo Miami. 

This is Tashi's fourth calf!

Tashi and her baby will remain off-exhibit so that the zoo's veterinary teams can monitor their progress.   The calf does not have a name yet and the zoo will announce at a later date when mom and baby will make their public debut.
