Ashy-throated Chlorospingus

The ashy-throated chlorospingus (Chlorospingus canigularis) or ashy-throated bush tanager, is a species of bird in the family Passerellidae, the New World sparrows. It is found in Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. == Taxonomy and systematics == The ashy-throated chlorospingus has a complicated taxonomic history. It was formally described in 1848 with the binomial Tachyphonus canigularis. It eventually was reassigned to the genus Chlorospingus that had been erected in 1851. Both Tachyphonus and Chlorospingus were at the time members of the family Thraupidae, the "true" tanagers, though their positions within the family were 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 ashy-throated chlorospingus has these five subspecies: C. c. olivaceiceps Underwood, 1898 C. c. canigularis (Lafresnaye, 1848) C. c. conspicillatus Todd, 1922 C. c. paulus Zimmer, JT, 1947 C. c. signatus Taczanowski & Berlepsch, 1885 At least one twentieth-century publication suggested that C. c. olivaceiceps deserved recognition as a…
