This page lists unresolved nocturnal bird call types currently recognised in the project. Each call type has its own page containing example clips, notes, and current evidence.
Neatly structured short liquid trill, recalling Buff-banded Rail, but higher pitched and a little longer.
Reminiscent of Pale-vented Bush-hen, fast piping notes around 800 Hz, can be interspersed with short upward-infected note around 850 Hz
Superficially moorhen-like, check whether this could be glider
This sound occurred just prior to definite possum noises, so that's probably what it is, but sounds eerily like a Tyto!
Maybe just a Sacred Kingfisher, but sounds softer and slower
Very short vaguely whistler-like call.
