whereabouts is this? On my previous visits the nilgai were next to the ostriches and cassowary (from one of your other photos, it seems the cassowary has moved to the other side of the park now?).
This is above the sambar enclosure and across the path from the two exhibits you mention, so presumably it's a refurb. I'm now wondering whether the cassowary was there, too, and it was emu on the other side of the park.
