Subspecies
Relationships within genus uncertain, pending completion of major genetic study. Taxonomy of present species requires further resolution. Regional differences in voice, plumage and eye colour suggest to some authorities that subspecies may represent more than one species. Some plumage variation appears clinal, but clines are discordant. Several subspecies, particularly within South America, may not be valid.

The following 16 subspecies are recognised:

  • cinereiceps (Sclater, PL, 1859)   -  Southern Mexico (Oaxaca and Veracruz east to Yucatán Peninsula) south to Costa Rica.
  • flavoolivaceus (Lawrence, 1863)   -  Eastern Panama and north-western Colombia.
  • asemus (Bangs, 1910)   -  Western and central Colombia.
  • exortivus (Bangs, 1908)   -  North-eastern Colombia and northern Venezuela.
  • berlepschi (Hartert & Goodson, 1917)   -  Trinidad.
  • cherriei (Hartert & Goodson, 1917)   -  Eastern Venezuela, the Guianas and northern Brazil (upper R Branco and Amapá).
  • duidae Zimmer, JT, 1939   -  Southern Venezuela and north-western Brazil (northern Amazonas perhaps to western Pará).
  • confusus Zimmer, JT, 1939   -  South-western Venezuela, eastern Colombia and north-eastern Ecuador.
  • aequatorialis (von Berlepsch & Taczanowski, 1884)   -  Western Ecuador and north-western Peru (Tumbes, Piura).
  • peruvianus (Taczanowski, 1875)   -  South-eastern Ecuador and northern and central Peru (Amazonas, southern San Martí­n, eastern Pasco, Juní­n).
  • insignis Zimmer, JT, 1939   -  North-eastern Peru (lower R Ucayali, in Loreto) and north-western Brazil (R Juruá east to R Jamundá and R Madeira).
  • mixtus Zimmer, JT, 1939   -  North-central Brazil (eastern Pará, north-western Maranhío).
  • inornatus Zimmer, JT, 1939   -  South-eastern Peru (northern Puno).
  • pallescens (Hartert & Goodson, 1917)   -  Central, southern and eastern Brazil (southern Maranhío, Piauí­ and Paraí­ba south to Mato Grosso, Bahia and possibly western Minas Gerais) south to Bolivia (Beni south to Tarija) and northern Argentina (south to Tucumán).
  • grisescens (Chubb, C, 1910)   -  Central Paraguay and northern Argentina (eastern Chaco and Formosa, northern Santa Fe).
  • sulphurescens (Spix, 1825)   -  Eastern Paraguay, north-eastern Argentina (Misiones) and south-eastern Brazil (eastern Minas Gerais and Espí­rito Santo south to Rio Grande do Sul).
