Typical Antbirds (Thamnophilidae)

Amazonian Antshrike (Thamnophilus amazonicus) - HBW 8, p. 559

French: Batara d'Amazonie German: Amazonien-Tropfenameisenwürger Spanish: Batará Amazónico
Other common names: Grey-capped Antshrike (cinereiceps)

Taxonomy: Thamnophilus amazonicus P. L. Sclater, 1858, Río Javari, north-east Peru.
Relationships uncertain; has been treated as forming a superspecies with T. caerulescens, but possibly closest to the T. punctatus superspecies. S of R Amazon plumage variation is clinal, but apparent habitat differences suggest that populations may be distinct, although geographical limits of the three S races are tentative; similarly, in NW, some specimens and sight descriptions from W Amazonia suggest intermediacy in plumage between nominate and cinereiceps, but plumage and habitat differences again support the maintaining of races; further research needed.

Race huallagae of T. punctatus has sometimes been considered to belong in present species. Five subspecies currently recognized.

  • divaricatus Mees, 1974 - extreme E Venezuela (E Bolívar), the Guianas, and NE Brazil N of R Amazon (E of R Branco and R Negro, E to N Pará and Amapá).
