Has Apenheul made a conscientious decision to showcase non-primate species in the future? Rodents, sheep, birds, pudu, warty pigs, etc, are all interesting to see but are they all fairly new additions to the park?
There's always been a background level of non-primates as long as I've been going there; the species seem to turn over a fair amount but have never been in enough numbers to distract from the primates - just enough to break them up a little and add a bit of variety. They certainly have an eye for an unusual species when it comes to choosing the non-primate mammal residents - last time (2004) they included Variegated Squirrels and some (passing-through!) Musk Oxen. One species we didn't see that was there fairly recently was Giant Anteater.
The musk oxen were "only" transit animals, going to gaiapark.
Apenheul has about 60% primates, 40% other animals, with recent additions of warty pigs, darwin rhea and ground hornbill. But also species who have left the collection like pecari (maybe still behind the scenes), anteater (died in may), yellow mongoose and cavia aperea.
But animals as the capybara's and pudu's are there already for quite a while
As far as I understand the former director of Apenheul was trying to expand the zoo's range by exhibiting more non-primate species. It was doing his "rule" that the park received warty pigs, anteaters, capybara and more. There was also talk of tapirs and giant river otters coming to the park and some point. Now it seems that they are going "back to basics".
