Following my recent visit I want to give some updates on the zoo:
There are no capuchins left at the zoo, there was only one individual left on my last visit so I assume it died.
Mongoose lemurs got a new separate enclosure in the large lemur exhibit, their previous exhibit had emperor tamarins.
Grivet monkeys presumably left the collection, their exhibit which was next to the grey langurs, was inhabited by a lone langur. I assume it is to prevent the langurs from breeding, as they've been having offspring for the past 3 or 4 years.
There was only one giraffe left, there were 3 on my last visit.
Lots of paths which allowed to get closer (sometimes too close) to exhibits were closed off.
Flamingos which were previously separated in two different exhibits (greater and lesser in one and American in the other) were moved together into the previous golden eagle exhibit. Black swans have replaced the American flamingos while the other exhibit remains empty.
Lowland tapirs have also left the collection, as the signage was removed and I did not spot any.
Other than these news, some species were moved into improved exhibits in the reptile house and an aviary that holds various species of common parrots (lories, ring necked parakeets etc.) and African grey hornbills, now has access to the indoor rainforest aviary (which is still not accessible to the public along with the aquarium).
