I don't think the structure is right for Thick-billed - bill too long, tail too short. The behaviour (in the bare branches, looking fairly active) I think also does not fit Thick-billed. I would agree that this is either Oriental or Clamorous, but I don't think it can be certainly ID'ed.
BTW, the stints in your other photos look like Long-toed rather than Temminck's (too 'upright' and too well marked for Temminck's)
Looks like an interesting site. I haven't heard of this site before.
