@1Squirrel monkey In one of the outdoor aviaries of the bird house. They are in one of the smaller aviaries on the jubilee complex side of the bird house. If I'm not mistaken they live in the aviary also housing blue-crowned laughing thrushes, in any case they live with other Asian bird species.
I really need to update my list of Antwerp's bird collection, but I haven't been to Antwerp since June 28th due to the local surge of Covid-19 in the area around Antwerp, and I don't know when I'll be going again.
I have to take the train to get to Antwerp and I would rather not right now unless I really have to (i.e. not for tourist reasons), given the Covid situation and reports that the Belgian railways aren't always doing enough to keep things as safe as possible on the trains and in the stations.
Also while the zoo is open, the bird house is, like all animal houses, currently closed due to Covid-19 restrictions, so even if I went I would not be able to get information on the indoor exhibits, and if I do the list I would like to complete it all at once.
I hope to go to Antwerp again, with the animal houses open again, somewhere this summer, and will try to remember to take the necessary photos and notes to do my list at that time.
I did take some pictures in September of 2020 of some of the indoor exhibits and associated signage, and I think I will include those species lists in my future gallery postings.
