Currently, the top area of the zoo is closed off for building works - so the path at the left-hand side ends at the viewing for the wild boar, and at the right you can view the ibex but go no further. Of the species shown here in that area, the Snowy Owls can be seen outside the elephant house, the Mouflon are mixed with the Fallow Deer and the (apparently lone) Alpine Chamois is sharing with the ibex.
There was also some building work around the primate islands, so we didn't see any lemurs, and unless I was being very blind then the porcupines also didn't appear to be present any longer.
