One of a pair of new cockatoo aviaries built since my last visit, on the side of the wallaby walk-through area. This one is a walk-through aviary and houses Red-tailed Black Cockatoos, a Citron-crested Cockatoo, Californian Quail, and Crested Pigeons. The Black Cockatoo pair can be seen in the photo, perched on the cross-beam.
