The juvenile is similar with the addition of dusky spotting on its breast.
Most of the brown-backed mockingbird's range is in western and southern Bolivia, from La Paz Department south. It also entends into northwestern Argentina as far south as Tucumán Province.
The brown-backed mockingbird inhabits arid landscapes of brush, desert shrubs, and hedgerows, often near human habitation. In elevation it mostly occurs between 2,300 and 3,500 m (7,500 and 11,500 ft) but can be found as low as 1,700 m (5,600 ft) and as high as 4,200 m (13,800 ft).
The brown-backed mockingbird forages mostly on the ground, but details of its feeding behavior and diet have not been published.
The brown-backed mockingbird breeds from November to March. It constructs a cup nest of twigs, often in cactus and sometimes in a bush. The clutch is four eggs. Essentially nothing else is known about its breeding phenology
The IUCN has assessed the brown-backed mockingbird as being of Least Concern. It is not a well-studied species, but appears to be common in suitable habitat and there are no known threats to the population.
