Yeah considering Gung is 24 years old, he’s just reaching his prime which is bizarre to imagine considering his eldest offspring is 15 years old and already a sire himself.
Of course Taronga noted (and as we all know) that Gung began siring calves at a much younger age than he would in the wild; and indeed, captive elephants typically mature earlier.
Ultimately, I think the success of the regional breeding programme has exceeded all expectation - going from having no calves born in over a century of keeping elephants in Australasian zoos; to 14 calves born since 2009.
Having bulls that are natural breeders has been hugely advantageous; with many of the region’s historic imports being behavioural non-breeders; or paired with non-viable cows.
