My experience of this species in Asia, and in the UK where it is a very rare visitor, is that it can be very retiring, and can remain hidden in/under bushes for long periods, feeding on the ground in a Nightingale-thrush like behaviour. Then,
at times, it will feed out in the open, again, terrestrially.
Good luck in relocating..
This species was long considered a Holy Grail for birders in the UK, and even though it has started turning up more regularly since a decade or so back, any sighting is still a popular draw in the UK
Good birding all
