Buntings and New World Sparrows (Emberizidae)

Black-and-rufous Warbling-finch (Poospiza nigrorufa) - HBW 16, p. 624

French: Chipiu noiroux German: Rotbrust-Ammerfink Spanish: Monterita Sietevestidos
Other common names: Black-and-chestnut/Chestnut Warbling-finch (whitii and wagneri)

Taxonomy: Emberiza nigro-rufa d’Orbigny and Lafresnaye, 1837, Santa Fe, Argentina.
New molecular data indicate that genus forms a clade with the tanager (Thraupidae) genera Hemispingus and Thlypopsis, and that Compsospiza, which often subsumed within present genus, is sister to that clade. Closest relatives of present species uncertain; further study required. Races whitii and wagneri sometimes treated together as a separate species, differing from nominate in song, habitat, and both juvenile and adult plumages; this treatment seems reasonable, but further details of these differences, in particular vocal differences, are needed.

Race wagneri poorly differentiated from whitii, and perhaps better synonymized. Three subspecies currently recognized.

Subspecies and Distribution:

  • wagneri Stolzmann, 1926 - La Paz (around Mt Chulumaní), in W Bolivia.
  • whitii P. L. Sclater, 1883 - Bolivia (Cochabamba, Santa Cruz, Chuquisaca and Tarija) and NW & NC Argentina (Salta, Jujuy and Tucumán S to E San Juan and N Mendoza, also W Córdoba and highlands of San Luis).
  • nigrorufa (d’Orbigny & Lafresnaye, 1837) - SE Brazil (Santa Catarina and Rio Grande do Sul), Uruguay and NE Argentina (E Formosa, Corrientes and Misiones S to E Córdoba, E La Pampa, E Rio Negro and Buenos Aires); non-breeding also SE Paraguay (Ñeembucú, C Paraguay and Alto Paraná regions).
