Until recently considered a race of H. cantator (which see). Is partly sympatric with H. peruviana and differs from this and all other species formerly grouped under H. cantator in its plain pale yellow throat to belly (3); very weak rufous flanks (2); pale olive-grey vs rufous-toned rump (2); and unique “common call” of two raspy notes (4); also appears to lack “chirr” calls of other species. Validity of race collinsi may require reappraisal. Two subspecies recognized.

Subspecies and Distribution
  • H. s. subflava Cabanis, 1873 – Andean foothills in EC Peru (Huánuco S to Cuzco).
  • H. s. collinsi Cherrie, 1916 – S Peru (SE Ucayali, E Cuzco, Madre de Dios, Puno), extreme SW Amazonian Brazil (Acre) and WC Bolivia (Pando, La Paz, W Beni, Cochabamba).

    Status and conservation

    Not globally threatened (Least Concern). Fairly common to common throughout most of its extensive range, e.g. in E Acre (Brazil), where it was only recently (since 1997)... read more
