The striated softtail (Thripophaga macroura) is a Vulnerable species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.

Their crown, back, rump, and uppertail coverts are dark reddish brown streaked with black-edged reddish-rufous to rufous-buff.

The rest of their underparts are dull brown with buff streaks that fade on the belly and undertail coverts.

It forages singly, in pairs, and in small groups that might be families, and usually as part of a mixed-species feeding flock.

It forages from the forest's understorey to the subcanopy, gleaning its prey mostly in vine tangles but also along branches and in foliage.

[3][4] The striated softtail's breeding season has not been defined but active nests have been found between September and January.

The striated softtail's song is an "unstructured mixture of short rattles, 'tjew-tjew-tjew' notes, and sparrowlike chatters" that is often sung in duet.
