S
starts withThe scale-throated hermit is about 14 to 14.5 cm (5.5 to 5.7 in) long. Males weigh 4.5 to 6 g (0.16 to 0.21 oz) and females 4 to 5 g (0.14 to 0.18 oz). This medium-sized hermit is olive green above with grayish underparts. Its dark throat whose feathers have lighter edges give the eponymous scaly appearance. The face has a black "mask" with a pale supercilium and gular stripe. Its tail feathers have white tips and the middle pair are longer than the others. The sexes are similar but the female has shorter wings and a less strongly decurved bill. The two subspecies have identical plumage but P. e. paraguayensis is significantly smaller than the nominate.
The nominate subspecies of scale-throated hermit is found in southeastern Brazil from southeastern Bahia south to Rio Grande do Sul. P. e. paraguayensis is found in eastern Paraguay and northeastern Angentina's Misiones Province. It inhabits the understory of a variety of landscapes within the Atlantic Forest biome including lowland and montane rainforest, semi-deciduous forest, and mature secondary forest. In elevation it has been recorded from 100 to 2,250 m (330 to 7,400 ft).
The scale-throated hermit is assumed to be sedentary but data are lacking.
The scale-throated hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a wide variety of flowering plants for nectar. It also consumes small arthropods.
The scale-throated hermit's breeding season in Brazil spans from September to March but has not been defined in the rest of its range. Its nest is a long cone-shaped cup made of plant fibers and spider web suspended under a long drooping leaf. They are often decorated with the lichen Spiloma roseum that stains the eggs and nesting female red. The clutch of two eggs is incubated by the female alone.
The IUCN has assessed the scale-throated hermit as being of Least Concern. Though its population size is unknown and believed to be decreasing, it is common throughout its range and occurs in several protected areas.
