Streak-throated Hermit
Phaethornis rupurumii
Drab hummingbird with a white tipped tail found in northern South America, ranging west as far as eastern Colombia. Like other hermits, it has a dark mask bordered by buffy stripes and a long bill. The blurry dark streaks on its throat and breast help to separate it from other similar species. These streaks are variable, and on adult males they nearly form a solid dark patch, but females and young birds may only show a few small blotches. Found in a variety of habitats including seasonally flooded rainforest along the Amazon and drier and scrubbier forest in hilly terrain. Uncommon to rare in most of its range.
识别特征
The streak-throated hermit is 10 to 12.1 cm (3.9 to 4.8 in) long and weighs 2.5 to 3 g (0.088 to 0.11 oz). It is generally brownish with a greenish back and brownish gray underparts. It has a black "mask" and white supercilium and malar stripe and a very dark brown throat that appears streaky. The sexes are generally alike.
分类信息
The streak-throated hermit was for a time considered a subspecies of the dusky-throated hermit (P. squalidus). It has two subspecies, the nominate P. r. rupurumii and P. r. amazonicus. They are geographically separated and the latter might be a full species.

分布与栖息地
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.
