Dusky Chlorospingus Chlorospingus semifuscus Scientific name definitions

Also known as the Dusky-bellied Bush-Tanager, this species is endemic to western Colombia and northwest Ecuador, where it is typically common in the region’s humid montane forests and borders. Like other bush-tanagers, it regularly associates with mixed-species flocks dominated by other tanagers, but may also be found in monospecific groups of up to 20 individuals (usually fewer). Its elevational range spans 700–2400 m at least. The Dusky Bush-Tanager should be easily identified within its comparatively restricted range, as other Chlorospingus in this region all have some yellow on the underparts or throat. The present species has the head and neck dark grayish, with olive upperparts and brownish-gray underparts, in some races becoming yellowish olive on the flanks. The eyes are yellowish white to reddish brown, depending on subspecies.
