Deb and I live in a kiwi zone, we hear them calling most nights. We got woken up at 5:45am to the sound of two of them outside our bedroom window fighting. They stayed a couple of minutes, after the show we thought "well we'll never see that again". But amazingly they came back for another two mornings, virtually to the minute, doing the same thing. The third visit we managed to get some footage on the big camera with Deb holding the red light. Have a watch, make sure you have the sound on.
