Yellow-whiskered Chlorospingus

The yellow-whiskered chlorospingus (Chlorospingus parvirostris) is a species of bird in the family Passerellidae, the New World sparrows. It is found in Bolivia, Colombia, Ecuador, and Peru. Some taxonomic systems call it the short-billed chlorospingus. == Taxonomy and systematics == The yellow-whiskered chlorospingus has a complicated taxonomic history. It was formally described in 1901 as a subspecies of the yellow-throated chlorospingus with the binomial C. flavigularis parvirostris. It retained that position through the middle of the twentieth century before being recognized as a full species. 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-whiskered chlorospingus has these three subspecies: C. p. huallagae Carriker, 1933 C. p. medianus Zimmer, JT, 1947 C. p. parvirostris Chapman, 1901 == Description == The yellow-whiskered chlorospingus is about 14 cm…
