Well I am a KIWI and the sound I make is "#@!*^$" most of time.
The Tui bird is used by RNZI (I think) when they change frequency (not
always but most of the time. It drives my Samoan wife bonkers when
she hears it for some reason unknown to mortal mankind and me. Her
sarcastic imitation of the birdcall is actually pretty good but I
aint letting that on...
