the bongo in australia are descended from 3 animals; taronga zoo sydney and western plains zoo dubbo imported 4 animals as two seperate pairs in the mid-1990s. since then quarantine has closed further importation of artiodactyls so what started off as an ambitious breeding program has somewhat stalled.
the second female died at WPZ during the birth of her first calf, which means that the population here has an effective founder base of just 3 animals.
the first female offpsring from the taronga program was transferred to WPZ, which has gone on to become the main breeding pair. from NSW bongo have been sent to South Australia and subsequently Victoria.
Zawadi, a male born at Taronga was recently transferred to Singapore Zoo. For now there is no offspring born to parent/offspring or full sibling pairs but you could expect to see this happening in the near future if our zoos decide against phasing them out through attrition and continue breeding. personally, i would favour the zoos keeping bongo, albeit inbred in the hope that in the future AQIS may allow the importation of semen or even live animals again and the population wont have to be built from the ground up.
