Yellow-throated Chlorospingus

The yellow-throated chlorospingus or yellow-throated bush tanager (Chlorospingus flavigularis) is a species of bird in the family Passerellidae, the New World sparrows. It is found in Colombia, Ecuador, Panama, and Peru. == Taxonomy and systematics == The yellow-throated chlorospingus has a complicated taxonomic history. It was formally described in 1852 with the binomial Pipilopsis flavigularis. It was eventually reassigned to genus Chlorospingus that had been erected in 1851. From its description until the early twenty-first century genus Chlorospingus was treated as a member of the family Thraupidae, the "true" tanagers, though its placement within the family was uncertain. Based on studies published in 2002, 2003, and 2007, beginning in 2010 taxonomic systems transferred Chlorospingus to its present sparrow family. The Chlorospingus species were originally called "bush tanagers" or "bush-tanagers". Beginning in 2013 systems began changing the English name of the members of the genus to "chlorospingus" because they were no longer considered tanagers. The yellow-throated chlorospingus' further taxonomy is unsettled. The American Ornithological Society, the IOC, AviList, the Clements taxonomy assign it these three subspecies: C. f. hypophaeus Sclater, PL & Salvin, 1868 C. f. marginatus Chapman, 1914 C. f. flavigularis (Sclater, PL, 1852) However, as of late 2025 BirdLife…
