The warbling-finches are a relatively speciose group that reaches its maximal diversity in the Southern Cone of South America, extending up into the Andes of Peru. Cinnamon Warbling-Finch is endemic to Argentina, and breeds in the Monte Desert, in western and south central regions of Argentina. In winter they have a tendency to move both northward and eastward. This east-west migration in Argentina is little studied, but appears to be performed by various species. Also this is a seed eater, and the seed stock in the Monte Desert varies dramatically depending on rainfall. The abundance of this warbling-finch also varies dramatically depending on rainfall; it appears to be somewhat nomadic, moving to the most food rich parts of the desert each breeding season. Cinnamon Warbling-Finch is an attractive bird, showing largely a grey face and upperparts with a chestnut patch on the mid back; and cinnamon underparts and supercilium. The wing is adorned with two broad white wingbars, which almost appear to join up as a wing patch.
