  • Brownish-grey throat and underparts, paler on centre of belly, sometimes with ochareous-olive wash forming a diffuse pectoral band

South America: found in Colombia and Ecuador.
A fairly common to common restricted-range species.



Clements recognizes these subspecies[1]:

  • C. s. livingstoni:
  • Pacific slope of Western Andes of Colombia
  • C. s. semifuscus:
  • Pacific slope of south-western Colombia (Narino) and western Ecuador
  • C. s. xanthothorax:
  • southwestern Ecuador (El Oro and adjacent western Loja)

Subspecies xanthothorax describes a population of birds found on the west side of the Andes which previously were included in the subspecies pheocephalus of Common Chlorospingus.


Cloud forest. Stays mainly inside the forest but visits sometimes fruiting shrubs at the forest border.
Recorded mostly at 1200 - 2300m in Ecuador and 900 - 2500m in Colombia.
More at lower levels and in interior of forest than Common Chlorospingus and Ashy-throated Chlorospingus.



Feeds on insects, small fruits and berries. Forages in small groups or pairs, often in mixed-species flocks. Forages actively, hopping along branches and perch-gleaning.


Nesting recorded in April and June. A described nest was made of grass and dry bamboo leaves and placed 7.5m above the ground in a tree.


A resident species.
