This is a nice looking aviary! Do you recall which species were found there? Based on the signs, it looks like it contains Ashy-headed Sheldgoose, Scarlet Ibis, and either Black-faced or Buff-necked Ibis.

Yes, both walk-through aviaries at Santiago were quite nice! The Ashy-headed sheldgoose and the black-faced ibis are kept in the first walk-through, and the second one, which is represented in this picture, keeps the following species:
Thank you for this list! Both aviaries have a nice mix of species and some (like the Austral Thrush and Ashy-headed Sheldgoose) that are rare or absent from North American zoos.

Indeed they look similar. One interesting point in the chilean aviary for me was how high the guest pathway is compared to the ground level. That brings a particularly interesting perspective of flight movements.
