Steinbach's Canastero

Steinbach's canastero is 15 to 16 cm (5.9 to 6.3 in) long and weighs 14 to 20 g (0.49 to 0.71 oz). The sexes have the same plumage. Adults have a pale supercilium on an otherwise grayish brown face. Their crown and back are dull gray-brown, their rump chestnut, and their uppertail coverts rufous-chestnut. Their wings are mostly rufous with dark fuscous outer halves to the flight feathers. Their tail's inner feathers are blackish fuscous with rufescent outer webs and the outer two pairs entirely rufous or chestnut. Their chin and throat are whitish with faint dusky specks, their breast and belly grayish, and their flanks and undertail coverts tawny-rufous or pale cinnamon. Their iris is brown to dark brown, their bill black to dark brown, and their legs and feet brown to black.

Steinbach's canastero is found in western Argentina from southern Salta Province south to Neuquén and Río Negro provinces. It inhabits arid montane scrublands, where it favors ravines, and monte woodlands. In elevation it ranges from 500 to 3,000 m (1,600 to 9,800 ft).

Little is known about the diet or feeding behavior of Steinbach's canastero. It is usually seen singly or in pairs and is believed to glean arthropods from the ground and low vegetation.
