That seemingly "vacant" part of the plan is the current Galapagos giant House and outdoor exhibit. So no ..., you wish for something that is not there to be.They might currently be in the asiatic hoofstock section, but I really do not know. In the construction plan for the Australia section there is an enclosure without any specified inhabitant to the lower right of the lorikeet aviary - perhaps the cranes will be moved there.
@antonmuster, thanks for the updated webcam pictures. To the left-hand side is possibly already the finished up Lorikeet landing, right?
