The chotoy spinetail (Schoeniophylax phryganophilus) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.
Adults of the nominate subspecies have a white supercilium and light brown ear coverts.
Juveniles have less sharp streaking on their uppersides than adults, a brown crown, a whitish chin, and an indistinct black throat patch.
Subspecies S. p. petersi is found disjunctly in northeastern Brazil's states of Minas Gerais, Bahia, and far separated in Piauí.
The species inhabits a variety of open to semi-open landscapes including treed savanna; gallery forest, thickets, and scrub along watercourses; monte woodlands; and the edges of marshes.
It typically forages singly or in pairs, gleaning prey from small branches and foliage within about 1 m (3 ft) of the ground.
[4] The chotoy spinetail breeds in the austral spring and summer, roughly late September to January.
The chotoy spinetail's song is "a distinctive series of low-pitched “cho” notes" that sound like they come from a larger bird.
