Pale-tailed Barbthroats are widespread throughout Amazonia, but they are typically local and uncommon throughout most of their range, which stretches from the Guianas to northern Bolivia. Typically found in lowlands and foothills, it frequents a wide range of forested habitats. Sooty Barbthroats (Threnetes niger) are sometimes considered part of the current species, although five subspecies have been described. The most common subspecies are characterized by pale malar streaks, rufous patches at the throat base, and pale tail sides. Most subspecies have predominantly green upperparts. Males have a fairly long, almost straight bill, while females have a slightly decurved one.
