Several of the subspecies are distinct both in plumage and voice (Restall 2006)

Distribution

Central and South America: found from Mexico through Central America, and South America to northern Argentina.

Taxonomy

Differences in plumage and voice indicate there could be more than one species involved; Restall indicates that such distinctions should be drawn between birds east and west of the Andes, but also between subspecies granadensis and semifasciatus.

  • T. m. granadensis: Caribbean slope of northern Colombia to north-western Venezuela
  • T. m. semifasciatus: Extreme eastern Colombia to southern Venezuela, the Guianas, northern and eastern Brazil
  • T. m. duidae: Tepuis of south-eastern Venezuela (Mount Duida)
  • T. m. melanurus: South-eastern Colombia to eastern Ecuador, eastern Peru and south-western Amazonian Brazil)
  • T. m. borbae: South-central Amazonian Brazil (Rio Purús to Rio Madeira)
