Many-striped Canastero
Asthenes flammulata
The many-striped canastero is 16 to 17 cm (6.3 to 6.7 in) long and weighs 17 to 27 g (0.60 to 0.95 oz). It is a large canastero and the most dramatically striped of them. The sexes have the same plumage. Adults of the nominate subspecies have a buff-whitish supercilium on an otherwise dark brownish face with buff to whitish streaks. Their forehead is bright tawny-brown or rufescent brown with dark brown stripes that widen to become the brown crown with rufescent streaks. Their upperparts from back to uppertail coverts are dark brown with conspicuous pale buff streaks. Voice: The many-striped canastero's song is an "accelerating series of buzzy notes that initially rises in pitch, and towards the end smoothly changes into a stuttering descending trill tzee-tzee-tzee-tzeetzeetzetztztztzrrrrrrr". It typically sings from a perch atop a shrub, and sometimes two birds countersing. The song differs little among the subspecies.

Adults of the nominate subspecies have a gray-brown face with a paler supercilium. Their crown is dull brown, their back and rump a slightly paler brown, and their uppertail coverts long and browner. Their wings are mostly dull rufescent brown. Voice: The sharp-billed canastero's song is "a 2-note trill, 'tsee-ee-ee-ee, tsee-ee-ee-ee' " and its contact call "a rising 'sweep' ".
