Islands Aviary at Te Wao Nui, Auckland Zoo.
This walk-through aviary holds Antipodes Island Parakeets and a pair of Campbell Island Teals. It is entered via a small research hut which contains several reptile exhibits (at the end the photo is taken at), and the exit is the door at right. The hut at the back is the birds indoor accomodation which is open to them during the day.
