This terrestrial species was common in primary forest, and
occasionally in secondary forest, in low trees or around brush
piles. On September 24, by "squeaking," I so aroused one bird that
it ran back and forth on a limb of a fallen tree in great
agitation. The specimen taken on November 12 was in heavy molt; it
lacked tail feathers and the primaries were being replaced.

This babbler tends to inhabit secondary growth more than does _T.
malaccense_ and was partly arboreal, occasionally ranging as high
as 20 feet above ground. It occurred occasionally in flocks of four
or five.
