The lark-like brushrunner (Coryphistera alaudina) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.

[3] The lark-like brushrunner is genetically most closely related to the firewood-gatherer (Anumbius annumbi), and they may be sister species.

[4][5][6] The lark-like brushrunner is the only member of its genus and has two subspecies, the nominate C. a. alaudina (Burmeister, 1860) and C. a. campicola (Todd, 1915).

Adults of the nominate subspecies have white around their eye that extends onto the ear coverts that are otherwise cinnamon-rufous.

It is found in southern Bolivia, northern and eastern Argentina, northwestern Uruguay, and slightly into the southernmost Brazilian state of Rio Grande do Sul.

[7][8][9] The lark-like brushrunner is mostly a year-round resident throughout its range but some of the southernmost move north in the austral winter.

[7][9] The lark-like brushrunner breeds in the austral spring and summer, roughly September to January or beyond.

What is thought to be the lark-like brushrunner's song is "a high-pitched, tremulous, tinkling trill, 'rrrrrew' or 'croe, criiii'".
