well i suppose from our point of view its seems good but to a normal zoo visitor they make think its a waste of time to visit the exhibit as it has no signifcant purpose to them
I haven't seen the new aviary, but I would be surprised if it 'didn't work'. Lorikeets are extremely pugnacious and noisy birds that work very well with visitors. As has already been mentioned Currumbin Sanctuary in Queensland has wild birds coming in as their chief attraction (yes they do get fed). I don't see that the public not being able to feed the birds should lessen the attraction. Walk-through aviaries are far more popular than viewing from the outside.
