My memory of that time is a little hazy, but I recall it as being decent. There were many indoor exhibits similar to the one this parrot are in that were adequate, nothing less. There was also a nice, dark kiwi exhibit. In the center of the building was a free flight aviary that seemed to be pretty nice and lush. Surrounding the building were a few cages and many yards for cranes, bustards, flamingos, ratites, ect. There was also a large outdoor walkthrough aviary accessable from a bridge from the building. It seemed nice but desolate.
A more regular visitor could probably provide more details. I didn't get to spend much time there, due to a family member becoming madly sick.
