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.
Sounds quite like a Pale-vented Bush-hen, but only a short series of notes.
Neatly structured short liquid trill, recalling Buff-banded Rail, but higher pitched and a little longer.
Unknown high pitched creak, not unlike a crazed Buff-banded Rail
Maybe just a Pacific Koel, but sounds odd and possible shorebirdy?
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
On 20 May 2026, at least two birds flying together (two calls in close proximity, calls get louder then stop)
Faint triple peep - looks to be structured like a bird call, with a thin downsweep on the spectrogram, but possibly a nonbird.
Unknown upsweeping call, not unlike the typical downsweeping Shining Bronze-cuckoo CALL.
Very short vaguely whistler-like call.
Unknown low piping sound, what could be making this?
