@Great Argus, I believe that where the Hyacinth Macaw photo is on the map, is an exhibit almost identical to this one in between the Safari Outfitters Store, and The Plant Trader, holding Salmon Crested Cockatoos.
@Anteaterman I do recall seeing one of the exhibits you mention and it was this one, knowing because I can see the entrance sign to Wings of the World in the background of the photo here. The "Birds can bite" sign was up I believe, but not the sign for the Hyacinth. There was no sign of anything in the exhibit.
