As per conversation with
@delia todd in separate post (
https://www.birdforum.net/gallery/bornean-bristlehead-pityriasis-gymnocephala-%E6%A3%98%E6%AF%9B%E4%BC%AF%E5%8B%9E.660531/), I extracted audio from my video clips of Borneo Bristlehead as per my Youtube video (
https://www.youtube.com/watch?v=_Y2lS7Lrcdo) between 1:27min - 2:23min and posted here.
This is audio from one of the clip. I'm can't find a way to add another audio in this post. So will have to post it in separate post later for audio #2.
In the audio, can hear clearly several Chestnut-rumped Babbler. There are also at least 4 Bornean Bristlehead at that same moment. Bornean Bristlehead calls were little difficult to hear as mostly overcast by esp Chestnut-rumped Babbler.
During that moment, both Chestnut-rumped Babbler & Bornean Bristlehead were seems hopping around from trees to trees. Doesn't looks like looking for food or feeding. My guessing could be courting.
I'm not sure if it is possible to separate and isolate the Bornean Bristlehead calls.
