Greater Flowerpiercer Diglossa major Scientific name definitions

No other Diglossa is found in the range of this, the largest flowerpiercer, which is endemic to the Pantepui region of southeastern Venezuela, adjacent Guyana, and northernmost Brazil. Its song—a scratchy rattling introduced by a series of tinkling notes—is seemingly quite different to that of any congeneric. Greater Flowerpiercer is an unmistakable bird, being mostly bluish slate on the head and body, but becoming darker over the upperparts with bluish shaft streaks on the crown and mantle, a black facial mask, a whitish submoustachial streak, and chestnut undertail coverts. It is confined to the slopes and summits of a few tepuis, usually in stunted woodland, and is most frequently encountered in pairs or alone.
