Are you sure about Great Argus? I didn't see one and there were no signs for it. There were signs for it leading to Wings of Asia but I didn't see one in there either.
@Najade - There are 2 birds here. Not sure what happened to the birds at wings of asia; maybe removed for breeding? Their aviary has red junglefowl and azure-winged magpies now.
@zooboy28 - They are inside the biodome. I believe this was the group that used to be free-ranged before. The zoo has plans for a smaller walk-through butterfly exhibit in that area.
