Introduction
The Reddish Hermit, Phaethornis ruber, is a very small hermit hummingbird of northern and central South America. It inhabits humid forest understories, forest edges, second growth and other densely vegetated habitats, where it searches for nectar and small arthropods. Unlike many brightly coloured hummingbirds, it often keeps to shaded vegetation and can be difficult to detect despite its distinctive rufous plumage.
Physical Description
The Reddish Hermit measures approximately 8–10 cm in length. It has dark olive-green upperparts, a bright cinnamon-rufous rump and rich rufous underparts. The head shows the typical hermit pattern of a dark facial mask with paler superciliary and moustachial stripes.
Its bill is long and decurved, with a yellowish or pale base to the lower mandible. The tail is relatively short for a hermit hummingbird and is dark rather than wholly white, with paler rufous or whitish edging and tips. The central tail feathers are slightly elongated, but they do not form the very long streamers seen in some related hermits.
Males commonly show a more obvious black patch or band across the breast. Females and immature birds may show a less distinct breast marking, and young birds generally appear duller overall. Plumage details vary geographically among recognised subspecies.
Range and Habitat
The Reddish Hermit occurs from Venezuela and the Guianas through much of Amazonian and eastern Brazil, extending west to eastern Colombia, eastern Ecuador, southeastern Peru and northern Bolivia. It is generally regarded as a resident species rather than a long-distance migrant, although local movements may follow flowering patterns and habitat conditions.
It occupies humid lowland and foothill forest, including terra firme forest, seasonally wet forest, swampy woodland, forest margins, clearings, wooded savanna and well-developed second growth. It is most often associated with dense understorey vegetation, small gaps and flowering plants. The species is mainly a lowland bird, but it may occur to roughly 1,000–1,100 metres in parts of its range.
Geographic variation is represented by several subspecies, including P. r. ruber, P. r. episcopus, P. r. nigricinctus and P. r. longipennis. Their ranges overlap the broad Amazonian and eastern Andean distribution of the species.
Where to See This Species
Rio de Janeiro Botanical Garden, Rio de Janeiro, Brazil
The Reddish Hermit has been recorded in the arboretum of the Rio de Janeiro Botanical Garden, where it used flowering plants throughout the year and displayed trapline-style foraging. The garden’s cultivated vegetation borders Atlantic Forest habitat, making shaded gardens, flowering shrubs and forest margins worthwhile places to search.
Nearby accommodation: Rio de Janeiro offers a wide range of hotels, guest houses, hostels and self-catering accommodation, particularly around Jardim Botânico, Botafogo, Copacabana and Ipanema.
Parque Lage, Rio de Janeiro, Brazil
Parque Lage is a publicly accessible green space beside the Tijuca Forest complex. Reddish Hermits have been recorded at the site, and the park’s combination of mature vegetation, forest edge, gardens and shaded trails provides suitable habitat. Look quietly around flowering plants and dense understorey, especially during the morning.
Nearby accommodation: The Jardim Botânico and Zona Sul districts of Rio de Janeiro provide hotels, guest houses, hostels and self-catering accommodation.
Cristalino Lodge and Reserve, Alta Floresta, Mato Grosso, Brazil
The Cristalino Lodge bird checklist documents the Reddish Hermit at the reserve, where it occurs in Amazonian forest and is recorded from suitable forest trails and clearings. The species may be encountered while watching flowering plants and scanning dense vegetation along the lodge’s forest paths.
Nearby accommodation: Alta Floresta is the practical gateway town, with hotels, guest houses and other visitor accommodation. The wildlife venue itself also provides lodge accommodation.
Behaviour and Diet
The Reddish Hermit is usually active during daylight and is often seen alone. It moves quickly through the understorey, hovering briefly at flowers or perching quietly in shaded vegetation. Like other hermits, it commonly follows a trapline, visiting a series of flowering plants in a regular circuit rather than defending a single feeding flower.
Nectar forms the main part of its diet. The long, curved bill allows the bird to exploit tubular flowers, and it may also take nectar by piercing flowers from the outside. Small insects and spiders supplement the diet and provide protein, particularly for growth and reproduction. While feeding, the bird can transfer pollen between flowers and act as an important pollinator.
Males may sing from inconspicuous perches and can display singly or in loose lek-like groups. The species is generally sedentary, although individuals may make local movements in response to flowering and other food resources.
Breeding information is less complete than for many better-studied hummingbirds. Reported nests are small, plant-fibre structures reinforced with spider silk and attached beneath leaves or other sheltered vegetation. The female undertakes nest construction, incubation and care of the young. A clutch commonly consists of two eggs.
Identification Tips
- Look for a tiny hummingbird with a bright cinnamon-rufous rump and rufous underparts.
- Note the long, down-curved bill and pale or yellowish base to the lower mandible.
- The head usually shows a dark mask bordered by pale facial stripes.
- The tail is relatively short and dark, with pale or rufous tips, not a completely white tail.
- Search shaded understorey, forest margins, small clearings and flowering plants rather than exposed canopy positions.
- The black breast marking is often strongest in males, but its visibility varies with sex, age, angle and posture.
- Similar small hermits can occur in the same forests, so bill shape, rufous underparts, facial pattern and tail pattern should be considered together.
Conservation Status
The Reddish Hermit is currently assessed as Least Concern by the IUCN. Its extensive geographic range and continued occurrence in suitable forest, secondary growth and other modified habitats reduce its immediate global extinction risk.
Nevertheless, forest clearance, agricultural expansion, pasture, urban development and degradation of humid understorey habitat can reduce local populations. Conservation of large forest blocks, riparian vegetation, forest edges and structurally complex second growth helps retain the flowering plants and nesting sites on which the species depends. Continued field surveys are also valuable because population trends and local abundance are not equally well documented across its range.
Frequently Asked Questions
Where can the Reddish Hermit be found?
The species occurs across much of northern and central South America, from Venezuela and the Guianas through Brazil to Colombia, Ecuador, Peru and Bolivia.
What habitat does the Reddish Hermit prefer?
It favours humid forest understorey, forest edges, clearings, swampy woodland, wooded savanna and dense second growth, mainly in lowland and foothill areas.
What does the Reddish Hermit eat?
It feeds mainly on nectar from a variety of flowers and supplements its diet with small insects and spiders.
Is the Reddish Hermit migratory?
It is generally considered resident and non-migratory, although local movements may occur when flowering and food availability change.
How can the Reddish Hermit be identified?
Look for a very small hermit hummingbird with olive-green upperparts, a bright rufous rump and underparts, a long decurved bill, pale facial stripes and a short dark tail with pale or rufous tips.
Is the Reddish Hermit threatened?
It is classified as Least Concern globally, but deforestation and the degradation of humid forest and understorey habitat remain important local threats.
