@snowleopard I'm not entirely sure, if that claim is 100 % accurate. Probably the whole Complex with the adjusted exhibits that hold South American birds and the offshow facilities ?
For example the Spirit of the Jaguar at Chester is around 6000 square metres with the space for the visitors.
Also the Parc des Felins has enormous fenced area for the Black Jaguars in addition to the other Jaguar Exhibit, but I am not sure if those are considered.
Everything else I've seen ( probably around 20) are smaller than Zlin's. Haven't seen Cabaraceno.
