Ovenbirds (Furnariidae)

Buff-browed Foliage-gleaner (Syndactyla rufosuperciliata) - HBW 8, p. 330

French: Anabate à sourcils fauves German: Ockerbrauen-Blattspäher Spanish: Ticotico Cejudo

Taxonomy: Xenops rufosuperciliatus Lafresnaye, 1832, Rio de Janeiro, Brazil.
Genus sometimes merged into Philydor; plumage, foraging behaviour and voice have suggested to some authors that it may be more closely related to Thripadectes than currently indicated in linear sequences. The taxon S. mirandae, described from C Brazil (Goiás) and subsequently treated as a race of present species, is in fact a synonym of Philydor dimidiatum. Proposed race squamiger, described from SE Brazil (Paraná), considered a synonym of nominate race by subsequent authors; proposed race similis, from NW Peru, described as like cabanisi<..

Taxonomy: Xenops rufosuperciliatus Lafresnaye, 1832, Rio de Janeiro, Brazil.
Genus sometimes merged into Philydor; plumage, foraging behaviour and voice have suggested to some authors that it may be more closely related to Thripadectes than currently indicated in linear sequences. The taxon S. mirandae, described from C Brazil (Goiás) and subsequently treated as a race of present species, is in fact a synonym of Philydor dimidiatum. Proposed race squamiger, described from SE Brazil (Paraná), considered a synonym of nominate race by subsequent authors; proposed race similis, from NW Peru, described as like cabanisi but more olivaceous (less rufescent) above, and paler and much less heavily marked below, but these differences not apparent in specimens from within a few km of type locality. Four subspecies recognized.

Subspecies and Distribution:

  • cabanisi (Taczanowski, 1875) - Andes of S Ecuador (Cordillera del Cóndor, in Zamora-Chinchipe), Peru (Piura, Cajamarca and S from Amazonas) and W Bolivia (S to Cochabamba).
  • oleaginea (P. L. Sclater, 1884) - Andes from C Bolivia (S from W Santa Cruz) S to NW Argentina (S to La Rioja).
  • rufosuperciliata (Lafresnaye, 1832) - SE Brazil (S Minas Gerais and S Espirito Santo S to Paraná).
  • acrita (Oberholser, 1901) - NC Paraguay and extreme SE Brazil (Santa Catarina, Rio Grande do Sul) S to NE Argentina (Chaco and Misiones S to NE Santa Fé and N Buenos Aires) and Uruguay.
