I went back to spend time with these Grey-headed Babbler (Stachyris poliocephala) but they are really ‘undergrowth specialists’ and I had only glimpses. I heard many calls and recorded some. The song comes in a number of variations – comprising 3 or 4 notes, lasting 2.5-3 seconds, and is repeated 7-10 seconds apart.
Below is a sonogram and waveform showing two such variations.
There is also a ‘high-pitched rattle’ (Wells) call of varying lengths – one example is shown below with 27 notes in 2.1 seconds.
Two call recordings are available below. The first one has a wider variation in song and calls. Also some individual softer notes.
