Bongo, waterbuck, Goliath heron, whistling ducks, white storks, white pelicans, comerants and Stanley cranes(?) Many other water fowl I don't remember the names of!
Yes it would be, but not as awesome as a hippo exhibit that you could actually walk up to and spend time at. Unless in conjunction with that they finally build a walking path below the monorail path. Now that would be truly awesome.
Not at this point on the track. This is about as far out from the monorail station as you can get. My personal perfect solution is put river hippos here and have pygmy hippos on a walking path with underwater viewing. That way you get the best of both world. We can dream can't we.
