Common Chlorospingus

Overview

The common chlorospingus (Chlorospingus flavopectus), also referred to as common bush tanager, is a small passerine bird. It is a resident breeder in the highlands from central Mexico south to Bolivia and northwest Argentina. C. flavopectus in the loose sense is a notorious cryptic species complex, and several of the up to 25 subspecies recognized in recent times are likely to be distinct species. Some populations in fact appear to be more distinct than several other members of Chlorospingus.
