Were you able to see the macaques, catfish, Chinese alligators, etc. on your latest visit? I remember when you first visited the pandas most of the exhibits did not have the animals in them yet.
The park is still not officially open yet, just the pandas and a few other bits visible via the Zoo. I don't think the species mentioned are visible yet (at least officially). This looks still to be an off-display (officially) part of the River Safari, as the plants in the foreground provide a barrier as they did in the photo from Zooish's previous visit: http://www.zoochat.com/1550/mekong-river-crab-eating-macaque-exhibit-300552/
Yeah zooboy28 is right, only the lesser adjutant storks are in view for now (along the short stretch leading to the pandas). The rest of the accessible exhibits lie empty and the large Mekong catfish tank has been completely covered up with a black sheet.
