Owl-faced monkeys (Cercopithecus hamlyni) in Europe

[Pertinax]

In Antwerp 2.1 Hamlyni's moved from the builing with small mankeys to the building with chimps and gorillas. Purpose is the introduction of them with the gorillas.

On January 16, an owl-faced monkey was born at Zoo Berlin. Mother is Pia.

The female there is Pia, born in Antwerp in 2014 from the same pair still living in Antwerp today. That pair, according to what I read, was not allowed to have any more young because hereditary rickets occurred in the young. Rickets which I think came from lack of sunlight in their former enclosure. That is why I am also curious to know whether they will breed again in Antwerp now that they can go out there and whether the young from Berlin will stay alive or whether they will also get this rickets. I am also curious as to why Doué la Fontaine, where they live in a top-notch enclosure, has never succeeded in breeding with this species, despite varying combinations of individuals.

The pair in Antwerp will most likely not breed again they're to old to successfully or safely raise another offspring after the last one Vince. Is what my sources claim.

and whether the young from Berlin will stay alive or whether they will also get this rickets..

Apparently the new young one in Berlin is the fourth from their pair- all are females and bringing their group to a total of 6, so all the young have survived. It also seems there is no problem with the offspring from the breeding in Berlin if its still continuing now. Terrible if housing was the only problem with the pair in Antwerp and now too old to breed anymore. Good they can now have access to sunshine though I am not entirely happy that to enjoy it they have to be mixed with gorillas.

Could it be due to some sort of stress- due to e.g. aggressive neighbouring species, or loud noise or some other outside factor?
