I was expecting better for what many would consider the number 1 zoo in the country in the late 70s.
I’m glad Taronga upgraded their chimpanzee’s accomodation with the opening of the Chimpanzee Park in 1980. Taronga’s chimpanzee community was well renowned (and still is) due to them holding a large colony of 20 chimpanzee, most of which had been born and raised within the colony.
Most zoos held held a pair or small group of chimpanzees and several city zoos in the region continued to do so until they phased out this species - Melbourne, Perth, Auckland and Adelaide for example.
It’d be a further decade and a half before the orangutans would see an improvement on their accomodation - with this species having bred equally well at Taronga.
