@Shaun_Casuarius It was taken in what was 'Royal Ramble' but looking at the flagstones it could be either Wings of Asia or Waterfall. Wings of Asia has those flagstones in the entrance area.

@Goura The photo's background is definitely from the central plaza of the Waterfall aviary, where most of the birds congregate during token feeding sessions.
Wings of Asia only bears flagstones and sandstone(?) pavement in its airlock, which most of the birds have no access to, unless they escape.
@Shaun_Casuarius I've seen the crowned pigeons in the foyer of Wings of Asia quite a few times actually, but I agree with you that it's probably the waterfall aviary
