A revision reinstated its placement in Malacocincla in 1985 while a 2001 study confirmed the cohesiveness of the Trichastoma group.

 and Bruce Beehler in 1985. The nominate population is from southern Burma and extands to southern Tenasserim and northwestern Malaya including the Langkawi Islands. Several other populations of this widespread species have been named as subspecies and not all are recognized. The population in the eastern Himalayas from eastern Nepal to Sikkim and Assam was named as amabile but is now considered within the nominate subspecies. Others include alterum (=altera, central Laos and Annam), williamsoni (eastern Thailand and northwestern Cambodia), obscurius (= obscurior, coastal southeastern Thailand), olivaceum (Peninsular Thailand and Malaya), sirense (Borneo, Pulau Mata Siri) and baweanum (Bawean Island).

of broadleaved evergreen forest, forest edge, secondary growth and scrub. In Singapore, they have been noted as being tolerant to disturbance and adapting to secondary growth and disturbed forest.

Behaviour and ecology

Abbott's Babbler usually moves around in pairs close to the ground. They breed from April to July (summer monsoon), with the nest being a carefully placed but bulky cup low in palms or other undergrowth. A study in Thailand found that most nests are placed in spiny palms and rattans. The usual clutch is 3 to 5 eggs which are bright salmon with dark blotches and red lines. When disturbed at the nest, the bird slip over the edge and fly with laboured wing beats and then hop out of sight. More than one brood may be raised in a season.

Their distincitive calls consists of three or four notes with the a drop on the middle note. The antiphonal duet of a male and female has the male leading with a "poor'ol bear" followed by the females "dear dear". The tunes may however change over time. The birds tend to remain within a well marked area and do not wander widely. The song is a variable short series of around three to four notes of rich, fluty, liquid, slurred, short whistled notes; these are sometimes delivered haltingly and sometimes rapidly. The evening group song consists of a recurrent sputtering churrr sound, which is low and slurred; ending with a sharp chreep. Calls include soft mewing notes, and a pulsing, purring trill when agitated.
