starts withThe crag chilia weighs from 31 to 40 g (1.1 to 1.4 oz) and is 18 to 19 cm (7.1 to 7.5 in) in length. O. m. melanurus is dark brown above with a rufous rump and flanks, grayish breast, and brown belly. O. m. atacamae is similarly colored but paler overall.
The crag chilia is endemic to central and north-central Chile between approximately 27° and 35° south latitudes. It is found primarily at elevations from 1,400 to 3,000 m (4,600 to 9,800 ft) but also at lower elevations in winter. Subspecies O. m. melanurus is found in the southern part of its range and O. m. atacamae is in the north.
It is found on shrubby rock hillsides and cliffs with sparse vegetation.
The crag chilia's diet is predominantly arthropods but also includes seeds. It is usually a solitary forager that gleans from rocks and probes crevices.
The species is presumed to be monogamous and its nesting season to be the austral spring and summer. The nest is a bulky ball of sticks lined with feathers and is usually placed in a rock cavity, though some have been found in holes in earth banks and rural buildings.
