Deep-blue Flowerpiercer Diglossa glauca


This beautiful and striking flowerpiercer is rather locally distributed over the east slope of the Andes, from southwest Colombia discontinuously south to northwest Bolivia, principally at altitudes below 2500 m. It is usually observed singly or in pairs, and these regularly join mixed-species flocks, especially those whose core constituents are Tangara tanagers. This is the only yellow-eyed flowerpiercer, which taken together with the wholly deep blue plumage should make the species immediately identifiable. There is narrow black frontlet, but this is difficult to see in the field, whilst females are overall marginally duller.
