Aviary for Rock Ptarmigan (Lagopus muta)

This is the aviary by the Polar Bear enclosure. They are also kept in the Japanese Bird House.

Where exactly was this enclosure? I looked for it but couldn't find it.

@DaLilFishie It's between the Polar Bear and Seals. If you look on the map, there is a four-path junction above the picture of the Polar Bear, and the aviary is in the pointed brown section between the pictures of the bear and seal (if that makes sense). The photo was taken from the path in front of the Polar Bear enclosure, and the path in the background of the photo is leading to the seals.
