This is an older call recording of a social group of Silver-eared Mesias (Leiothrix argentauris tahanensis), sitting in a ‘thicket’ and chattering away. The chattering calls were done simultaneously by a few birds (2-3) at the same time. They were fast calls and occurred at 15-20 notes per second and of varying intensity. They sounded like distress calls but I could not appreciate any threat.
Sonogram and waveform is shown below.

The Xeno-canto currently restricts recordings of this species due to bird trapping (can upload but not hear them).
