Australia's Noisiest and Quietest Bird?
Quite apart from the sound of their flight, they
(White-throated Needletails) also are quite vocal when doing chasing displays.
They emit a high-pitched rapid twitter. Probably most of the time they are too
far away to hear. I published a note about this "Chasing and Vocalisation
by White-throated Needletails" in Canberra Bird Notes, 13(4):130-131 (1988)
and I think (but am not sure) that was included in HANZAB.

Actually
WTNs make quite a bit of noise as they are slicing through the
air at
high speed. You can hear the wind in their wings at 20 metres
...
