Buntings and New World Sparrows (Emberizidae)

Chestnut-breasted Mountain-finch (Poospiza caesar) - HBW 16, p. 626

French: Chipiu césar German: Kaiserammerfink Spanish: Monterita Pechicastaña
Other common names: Chestnut-bellied/Cuzco Mountain-finch, Chestnut Warbling-finch

Taxonomy: Poospiza caesar P. L. Sclater and Salvin, 1869, Tinta, Cuzco, Peru.
Formerly classified in its own genus, Poospizopsis. New molecular data indicate that present genus forms a clade with the tanager (Thraupidae) genera Hemispingus and Thlypopsis, and that Compsospiza, which often subsumed within this genus, is sister to that clade. A molecular-genetic study of various members of the genus suggests that present species is sister to P. hypocondria. Monotypic.

Distribution: Andes of Apurímac and Cuzco, in SE Peru.
