Taxonomy and systematics
The chestnut-backed antshrike has these four subspecies:[2]
- T. p. palliatus (Lichtenstein, MHC, 1823)
- T. p. vestitus (Lesson, RP, 1831)
- T. p. puncticeps Sclater, PL, 1890
- T. p. similis Zimmer, JT, 1933

Description
The lined antshrike is 16 to 17 cm (6.3 to 6.7 in) long and weighs 26 to 28 g (0.92 to 0.99 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true
Subspecies T. p. similis is similar to the nominate. Both sexes of subspecies T. p. puncticeps are paler overall than the nominate, and females have a strong yellow-ochre wash on their nape. Subspecies T. p. vestitus has even paler upperparts than puncticeps and wider dark bars on their underparts than the other three subspecies.[5][6][7]

Behavior
Movement
The chestnut-backed antshrike is presumed to be a year-round resident throughout its range.[5]

The chestnut-backed antshrike's diet is not known in detail but includes a variety insects and also other
Breeding
The chestnut-backed antshrike's breeding season has not been fully defined but spans October to January in southeastern Brazil. It appears to start in November in Amazonian Brazil and perhaps extends to June. The species' nest is a small deep cup loosely woven from fungus, root, and other plant fibers and sometimes covered with green moss. It is hung by its rim in a branch fork, often between 1.5 and 3 m (5 and 10 ft) above the ground in a dense thicket. The usual clutch size is two eggs. The incubation period, time to fledging, and details of parental care are not known.[5]
Vocalization
The chestnut-backed antshrike's song is "a moderately long...accelerating series of similar, rapidly delivered, somewhat nasal notes, pitch rising slightly initially, more clearly falling towards end, terminating in longer, firmly accented, downslurred note".[5] It has been written as kah kah-kah-kah-ka'ka'ka'kaka'pah".[7] Its calls include an "emphatic short nasal note" and a "longer, upward-inflected, squeal".[5] The first has been written as "awr!; another call is "a mewing whistled wheeu".[7]
