Every zoo building, new or old, has a bunch of flaws discovered once the construction is finished and you put the animals in it. Some are easily repairable and with some you just have to deal in some way...The thing is, some of these probably wouldn't even exist, if you'd give it a bit more thought in project stage.
Having good relationship with some of Plzen's primate keepers, we are discussing these things very often, and we all agree that for a recently-opened building, the South American house isn't what it probably could've be.
The main issues of the house:
- The exhibits could be much higher, giving animals more climbing opportunities, especially the outter parts.
- The animals can see each other on the opposite sides of the house - apparently the more agresive species feel the need to protect their territory and harass the animals on the other side, who were not taking it well. (This was already fixed I think with changing the species list a bit)
- There are no service corridors/entrances, so the keepers have to enter the exhibits from public space.
- + some more minor problems.
