Forest Aviary at Te Wao Nui, Auckland Zoo.
This walk-through aviary contains many forest birds of New Zealand. It first opened in the early/mid 1990s but has been closed for the last few years for extensive repairs and renovations. This photo is taken near the entrance, the path winds around to the left and stairs lead up to the high viewing platform (where green bird feeder is) before winding down and round to the platform at right, and the exit further right (out of shot). Species present are North Island Kaka, Yellow-crowned Parakeets, Red-crowned Parakeets, New Zealand Wood Pigeon, Bellbird, Silvereye, Tui & North Island Saddleback. Bizarrely there are no ground-dwelling birds or waterfowl, despite the pond. Hopefully these will be added later.
