Buntings and New World Sparrows (Emberizidae)

White-winged Diuca-finch (Diuca speculifera) - HBW 16, p. 616

French: Diuca leucoptère German: Spiegelammer Spanish: Diuca Aliblanca

Taxonomy: Emberiza speculifera d’Orbigny and Lafresnaye, 1837, Bolivia.
Previously thought to form a superspecies with D. diuca, but aspects of morphology, voice and typically hopping (rather than walking) locomotion suggest that it is not close to that species; likely more closely related to Phrygilus erythronotus and Phrygilus dorsalis. Race magnirostris doubtfully distinct from nominate. Two subspecies provisionally recognized.

Subspecies and Distribution:

  • magnirostris Carriker, 1935 - highlands of C Peru (Ancash to Junín and Huancavelica).
  • speculifera (d’Orbigny & Lafresnaye, 1837) - Andes of SC & S Peru (S from Arequipa, Cuzco and Puno; probably also this race in Ayacucho and Apurímac), N Chile (Arica–Parinacota and Tarapacá), W Bolivia (La Paz, Cochabamba and NW Oruro), and NW Argentina (Jujuy).
