Not a collection that I had previously heard of but saw today that they rather excitingly hold four-eyed opossum (as well as a range of farmyard animals, 'farmyard' exotics like meerkat, and raptors). Looking forward to a visit very soon.
The nocturnal house is very good, I visited in March, however the rest of the farm is very targeted towards children. There is a species list by @TeaLovingDave here: Rare and new at the zoos of europe
Actually, past the typically species and the farmland, the collection is quite good. Tailess tenrec, jerboa, Long-eared hedgehog, casque-headed iguana, African house snake and a nice selection of birds-of-prey. I'll take a look in if I'm anywhere near it.
Something I forgot to mention was that the rare and exotic species are not owned by the farm, but the imperial bird of prey academy which operates on their land
Visited today to take part in their nocturnal experience and sad to announce they only have one four-eyed opposum remaining. For anyone planning a visit I would go sooner rather than later as the remaining female is heading towards her twilight year(s). They also lost their long eared hedgehog recently, and no longer hold jeroboa.
You must have been there at roughly the same time that I was there. Glad to know about the jerboas, as I spent quite a long time looking for them. I wonder if you took any notes about the birds of prey - especially the eagle owls. I have in my notes that there were Bengal and African striped eagle owls on display but am certain I didn't write down one of the species. Presumably it was Eurasian, but it is annoying me! Additionally, for any other visitors, the farm area is worth exploring, as they have some beautiful Oxford Sandy and Black piglets as well as an enormous and charming walk-through aviary with various 'pet-shop' finches and canaries (but which makes a good display).
They had a Eurasian crossed with something else, but can't remember what it was, possibly Siberian...
According to ZTL the collection no longer holds the species but I can't find a source corroborating this. Does anyone have any further information or did the female just pass away without any public acknowledgement from the zoo?
