Least Concern

Striated Antthrush (Chamaeza nobilis)


French: Tétéma strié German: Weißkehl-Ameisendrossel Spanish: Tovacá noble

Chamæza nobilis


, 1855,

Chamicuros, Peru


Probably closest to C. campanisona and C. meruloides. Race fulvipectus differs vocally from others: although structurally and tonally very similar (in two parts, first an accelerating series of notes, second a slow even series of notes), song is much shorter, lacking the long-drawn fast “bubbling” series at end of first part. Racial identity of birds from EC Amazonian Brazil (R Purus E to R Madeira) uncertain; further study needed. Three subspecies recognized.

Subspecies and Distribution
  • C. n. rubida J. T. Zimmer, 1932 – N of R Amazon in SE Colombia, E Ecuador and NE Peru; presumably also in immediately adjacent W Brazil.
  • C. n. nobilis Gould, 1855 – Western Striated Antthrush – S of R Amazon from E Peru (S from Huallaga Valley) E to WC Brazil (E to at least R Purus, probably to R Madeira) and S to extreme NW Bolivia.
  • C. n. fulvipectus Todd, 1927 – Eastern Striated Antthrush – NC Brazil at Santarém, left bank of R Tapajós, recorded in Tapajós–Xingu interfluvium#R; probably also including birds W to R Madeira and possibly those S to N Rondônia.
