Melbourne Zoo's Asian Elephant Num-Oi has given birth overnight.

Her 22-month pregnancy concluded at 2:50am with the birth of a little boy.

Num-Oi was outdoors in the company of Kulab and her two-year-old calf Ongard. Mali, Dokkoon, and Mek Kapah were nearby and able to see the event taking place.

The newborn is the first calf for Num-Oi, and he is the fourth baby for the Zoo’s fertile bull elephant Bong Su.

According to the keepers and vets, Num-Oi is being a very attentive and supportive first time Mum.
