The Bluish Flowerpiercer is a species of bird in the Thraupidae family. It is found in humid montane forest in Venezuela, Colombia, Ecuador, Peru and Bolivia.
The Diglossa caerulescens is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
Diglossa caerulescens was formerly treated in the monotypic genus Diglossopis, but was included in Diglossa by Hellmayr (1935). Bock (1985) proposed separating glauca, caerulescens, and cyanea in the genus Diglossopis, and he interpreted morphological data to indicate that this and Diglossa were not sister genera. This classification was followed by Sibley & Monroe (1990), who also added D. indigotica to the genus based on Vuilleumier’s (1969) species groups. More
