Baby Boy Boom: Taronga Zoo Gets A Big Delivery

Welcome to the world little (or should I say BIG) one!

Sydney's Taronga Zoo has welcomed the birth of a baby Asian elephant.

Mother Pak Boom gave birth to the the 130 kilogram, yet-to-be-named calf on Friday morning.

Taronga's senior veterinarian Larry Vogelnest told the ABC the birth of Pak Boom's second calf was relatively quick, despite a pregnancy that lasted almost two years.

"It was a very quick and easy birth," he said.

"The little calf was standing within minutes of the birth and suckling within a couple of hours."

Despite her 22-month-pregnancy, Pak Boom was reportedly in labour for just an hour.

Baby boy Boom's birth has brought Australasia's Asian elephant population to 25.

He will be kept in a paddock distanced from the public for a fortnight before making his public debut in an official naming ceremony.
