Anabates certhioides

Corrientes, Argentina


In past, sometimes considered conspecific with T. harterti. Geographical variation may be partly or entirely clinal, and validity of races questionable; quantitative study of plumage coloration required. Three subspecies recognized.

Subspecies and Distribution
  • T. c. estebani (Wetmore & J. L. Peters, 1949) – extreme SC Bolivia (Santa Cruz), N Argentina (Jujuy and Catamarca E to Chaco and S to Córdoba) and W Paraguay.
  • T. c. luscinia (Burmeister, 1860) – W Argentina (San Juan, La Rioja and W Córdoba S to Mendoza and N San Luis).
  • T. c. certhioides (d’Orbigny & Lafresnaye, 1838) – NE Argentina (E Formosa and C Corrientes S to E Río Negro and SW Buenos Aires); recorded in extreme SW Rio Grande do Sul, in S Brazil#R.
