Bluish Flowerpiercer Diglossa caerulescens


Compared to the Masked Flowerpiercer (Diglossa cyanea), with which this species is perhaps most liable to be confused, especially given their largely overlapping ranges (from northern Venezuela to northern Bolivia), this species is much duller and more grayish blue, especially below. Furthermore, it lacks any trace of black on the face—the plumage being very uniform—and the reddish irides of the Bluish Flowerpiercer are much duller than those of the Masked Flowerpiercer. These two species are regularly found in the same mixed-species flocks, although Masked Flowerpiercer is usually the more numerous of the two. Like other flowerpiercers, it feeds by puncturing flowers to glean their nectar, but also takes insects and some small fruits.
