Buntings and New World Sparrows (Emberizidae)

Abert's Towhee (Pyrgisoma aberti) - HBW 16, p. 599

French: Tohi d’Abert German: Schwarzkinn-Grundammer Spanish: Toquí de Abert

Taxonomy: Pipilo aberti S. F. Baird, 1852, “New Mexico” = vicinity of Gila Bend, Maricopa County, Arizona, USA.
Formerly placed in genus Pipilo and sometimes in Melozone. Molecular analysis indicates that present species and P. crissale are sister-taxa. Geographical variation clinal; species perhaps better treated as monotypic. Proposed race voorhiesi (described from c. 15 km S of Tucson, in Arizona) treated as synonym of dumeticolus. Two subspecies tentatively recognized.

Subspecies and Distribution:

  • dumeticolus (van Rossem, 1946) - SW USA from SW Utah S through Colorado Valley in SE Nevada to SE California, and E along Gila R in S Arizona, also extreme NW Mexico (extreme N Baja California and NW Sonora).
  • aberti (S. F. Baird, 1852) - SW USA in S Arizona and SW New Mexico.
