Austral Canastero

The austral canastero is 15.5 to 16.5 cm (6.1 to 6.5 in) long and weighs 21 to 23 g (0.74 to 0.81 oz). It is the southernmost canastero, and one of several streaked canasteros that have drab plumages with dark stripes on their upperparts. It has a shorter tail than many other canasteros. The sexes have the same plumage, but there is much individual variation. Adults have a whitish or pale buff supercilium and dark dusky lores on an otherwise sandy brownish face. Their crown, back, and rump are sandy brown with conspicuous blackish streaks. Voice: The austral canastero's song is a "short rising trill repeated several times with intervals of a few seconds". It mostly sings during the breeding season, during the morning and late afternoon, and from atop a small bush. Its call is a " very short metallic tick, repeated in loose series".
