yeh, thats all well and good, but im sure the studbook keepers are doing their jobs and im sure if the two taronga females are going to europe, as two have before, its because they are needed there now, to pair with mature, suitable males now. not in ten years time when perth develops and exhibit for them, etc, etc.
taronga is already utilising its old (but high standard) guenon exhibit for bachelor gorillas, and i dont think, with such limited room here, that melbourne needs to establish a second troop in a sub-standard enclosure when these two animals are needed in europe for breeding.
