Cinereous Warbling-Finch

The cinereous warbling finch (Microspingus cinereus) is a small tanager in the family Thraupidae, found in the dry scrub and open woodland of Bolivia and northwestern Argentina, particularly in the inter-Andean valleys and eastern slopes of the Andes at elevations from about 500 to 2,000 meters. It inhabits thorn scrub, dry Chaco-type woodland, and arid mountain valleys, foraging in low shrubs and on the ground for seeds, berries, and invertebrates. The plumage is largely gray above with a whitish eyebrow and pale underparts with faint streaking. The cinereous warbling finch is classified as Least Concern by the IUCN, reflecting a small but apparently stable range within its interior South American distribution. The genus Microspingus contains several species of warbling finches distributed in the Andean foothills and inter-Andean valleys. Like many dry-habitat South American birds, it faces threats from overgrazing, scrub clearing, and agricultural expansion in its restricted range. The species is absent from Europe; database records citing Norway are erroneous data entry artifacts. Population monitoring within its Bolivian and Argentine range is limited, and further surveys are needed to confirm population stability. It is occasionally encountered on birdwatching tours in the drier valleys of northwestern Argentina.
