Tanagers (Thraupidae)

Sooty-capped Bush-tanager (Chlorospingus pileatus) - HBW 16, p. 304

French: Chlorospin à sourcils brisés German: Weißbrauen-Buschtangare Spanish: Clorospingo Cejiblanco
Other common names: Pileated Bush-tanager; Volcano Bush-tanager (“zeledoni”)

Taxonomy: Chlorospingus pileatus Salvin, 1865, Volcán Irazú, Costa Rica.
Recent molecular-genetic studies indicate that this genus and Nesospingus, Spindalis and Phaenicophilus form a monophyletic clade that is sister to several New World warbler (Parulidae) genera (including Dendroica, Basileuterus and Vermivora), and are not closely related to other genera of present family. More recent evidence suggests that Chlorospingus is closest to genus Arremonops in family Emberizidae. The form “zeledoni”, originally described as a separate species, now considered to be only a colour morph of present specie.. View all taxonomy...

The form “zeledoni”, originally described as a separate species, now considered to be only a colour morph of present species; known only from Volcán Irazú and Volcán Turrialba, in Costa Rica. Birds from Cerro Flores, in E Chiriquí (Panama), supposedly with yellower underparts and whiter central abdomen, described as race diversus, but appear inseparable from those in rest of species’ range. Monotypic.

Distribution: Mountains from C Costa Rica S to W Panama (Volcán de Chiriquí).
