The Kiwi is the National bird of New Zealand, however, as it is endangered and nocturnal, you will almost never see one in its natural environment. Because of this there are several small Kiwi houses built primarily for tourists to come and see the Kiwis in an artificial environment made as natural as possible for the Kiwis.
This building has four outer walls and a roof. Inside is a circular structure with mostly glass walls. Inside two or three Kiwis roam around in their created environment of plants, earth, etc. Lighting is very low (like walking at night) as the Kiwis are nocturnal.
They are about the size of a chicken, but no other similarities. They have long, thin beaks, poor eyesight, and good hearing and smell. One Kiwi was apparently battling with another for territorial rights when we were there. You can't really go to New Zealand without seeing a Kiwi, but most of us will probably find that one visit is enough.
