Red Data Status :Least Concern
Remarks :This Taiwan endemic of high montane forest is a tiny, fast moving bird, usually in the dark undergrowth; making for challenging observations. HBW 2019 describes both a dark and a pale morph but I am not able to find similar descriptions in other references. I managed to record the song and an edited recording is here: https://soundcloud.com/amar-singh-hss/taiwan-wren-babbler-calls-3-1-daxueshan-national-forest-recreation-area-taichung-city-county-taiwan-17th-january-2018 Brazil (2009) rightly describes the song has having a first note separated from the rest this is heard well when you record and play back the song but can be missed in the field. The song comprises 6 notes. The first note that starts off the song is not well seen on the sonogram but clear on the waveform. It is followed by a rapid sequence of 5 notes that have both a high frequency and low frequency sound (quite complex). The song last approximately 1 to 1.2 second and is repeated 6-26 seconds apart (spacing 13, 18, 26, 13, 10, 9, 6, 9 seconds recorded).
