Typical Antbirds (Thamnophilidae)

Grey Antbird (Cercomacra cinerascens) - HBW 8, p. 631

French: Grisin ardoisé German: Aschgrauer Ameisenfänger Spanish: Hormiguero Gris
Other common names: Sclater’s Antbird (sclateri and iterata combined)

Taxonomy: Formicivora cinerascens P. L. Sclater, 1857, Río Napo, Ecuador.
Relationships uncertain; thought by some authors to be a sister-species to the “C. nigricans species group”, or intermediate between the two major Cercomacra species groups. Populations fall into two pairs; nominate race and immaculata may prove to be a different species from sclateri and iterata, but differences between races within each pair (especially first of those) may be clinal. Four subspecies recognized.

  • cinerascens (P. L. Sclater, 1857) - S Venezuela (W & S Bolívar, Amazonas), SE Colombia, E Ecuador, NE Peru (N of R Amazon and R Marañón) and NW Amazonian Brazil (N Amazonas, Roraima, N Pará W of R Nhamunda).
  • immaculata Chubb, 1918 - E Venezuela (E Bolívar), the Guianas and NE Amazonian Brazil (Amapá, N Pará E of R Nhamunda).
