Distribución y hábitat

The nominate subspecies of streak-throated hermit is found from the extreme eastern part of Colombia's Vichada Department through central and eastern Venezuela and western Guyana into northern Brazil's Roraima state. P. r. amazonicus is found in north-central Brazil along the Amazon River east of the Negro River. The species inhabits the understory at the edges of rainforest and the interior of várzea forest. It also inhabits drier and more open landscapes such as semi-deciduous and gallery forest, scrublands, river islands, and secondary forest. It is primarily a bird of the lowlands but reaches as high as 500 m (1,600 ft) in Venezuela and Guyana.
