Introduction
The Long-billed Hermit, Phaethornis longirostris, is a large hermit hummingbird of humid tropical forests in Middle America and north-western South America. It is recognised by its long, decurved bill, subdued brown-and-green plumage, strong facial pattern and elongated central tail feathers with pale tips.
Physical Description
The Long-billed Hermit measures approximately 13–16 centimetres in length. It has mostly brownish-green upperparts, paler greyish-buff to brown underparts and a dark mask through the eye bordered by pale facial stripes. A pale central stripe may be visible on the throat.
The bill is long, slender and distinctly decurved. The central tail feathers are elongated and end in conspicuous pale or white tips, which can be noticeable when the bird is feeding or hovering. The sexes are broadly similar in plumage, although individual variation and regional differences occur. Young birds are generally duller and may show less clearly defined facial and tail markings.
Range and Habitat
The Long-billed Hermit is a resident species distributed from southern and eastern Mexico through Belize, Guatemala, Honduras, Nicaragua, Costa Rica and Panama, continuing into northern and western Colombia. The wider Phaethornis longirostris complex has also been associated with western Ecuador and north-western Peru, although the treatment of some southern populations varies between taxonomic authorities.
It inhabits humid lowland and foothill forest, forest edges, riverine vegetation and secondary growth. It may also occur in plantations, gardens and other modified landscapes where dense cover and suitable flowering plants remain. In Costa Rica, it has been documented in both intact and secondary rainforest, including areas with heliconias and other tubular flowers.
The species is generally sedentary rather than migratory. Local movements may occur as birds follow flowering plants and other food resources.
Where to See This Species
Área de Conservación Guanacaste, Guanacaste, Costa Rica
The species has been documented in the Del Oro Sector of the Área de Conservación Guanacaste, including Río Chón and other forested sites. Look in humid forest, secondary growth and shaded areas with heliconias, Passiflora and other flowering plants. Males may be detected from low perches by their repeated calls.
Nearby accommodation: La Cruz and Liberia provide practical bases with hotels, guest houses and lodges. Accommodation within or near individual conservation sectors may be limited, and entrance arrangements should be checked before travelling.
Refugio Nacional de Vida Silvestre Playa Hermosa-Punta Mala, Puntarenas, Costa Rica
The Long-billed Hermit is included in the refuge’s bird records. Forest patches, riverine vegetation and areas of dense secondary growth offer the most suitable habitat, particularly where flowering plants are present. The species may be easier to locate during quiet walks in the cooler morning hours.
Nearby accommodation: Jacó and the surrounding coastal settlements offer hotels, guest houses, self-catering accommodation and small lodges.
Parque Nacional Natural Paramillo, Córdoba and Antioquia, Colombia
The Long-billed Hermit is included in biodiversity records for Parque Nacional Natural Paramillo. Forested foothills, humid valleys and dense understorey provide appropriate habitat. Access is regulated and conditions can vary between sectors, so visitors should obtain current permission and safety information before planning a visit.
Nearby accommodation: Tierralta is the main practical gateway, with local hotels, guest houses and basic accommodation.
Behaviour and Diet
The Long-billed Hermit is active during the day and usually forages alone. Like other hermits, it commonly uses trap-lining, following a regular route between scattered flowers rather than defending one concentrated feeding territory. This behaviour allows it to exploit flowering plants across a wide area.
Nectar supplies most of its energy, particularly from long-tubed flowers such as heliconias and other forest plants. It also captures small insects and spiders, which provide protein and other nutrients. The bird often moves quickly through shaded understorey and may hover briefly at a flower before continuing along its route.
Males sing from low perches and may use repeated calls and tail movements during courtship. The female alone builds the nest and cares for the young. The nest is made from fine plant material, moss, roots and spider silk, and may be attached to the underside or tip of a leaf, often near a stream or other damp habitat. Two white eggs are normally laid, and incubation lasts approximately 17–19 days.
Identification Tips
- Look for a relatively large, dull-coloured hummingbird moving through shaded understorey.
- The very long, down-curved bill is usually the most obvious feature.
- Note the dark facial mask bordered by pale stripes and the pale central throat marking.
- The elongated central tail feathers have pale or white tips and may be held conspicuously during feeding.
- The species is more likely to be encountered travelling between flowers than defending a single feeding patch.
- Other hermit hummingbirds may appear similar, so bill length and curvature, facial pattern, body size and the pale-tipped central tail feathers should be considered together.
Conservation Status
The Long-billed Hermit is assessed as Least Concern globally. No reliable current population estimate is provided here, and the available sources do not establish a confirmed global population trend.
The principal potential threats are the loss and fragmentation of humid forest through deforestation, agricultural expansion, plantation development and urban growth. Maintaining forest corridors, riverine vegetation, secondary woodland and flowering plants can help preserve feeding and nesting habitat. Protected areas across its range provide important refuges, although conservation management remains necessary where forests are isolated or under pressure.
Frequently Asked Questions
Where is the Long-billed Hermit found?
It occurs from southern and eastern Mexico through Central America to northern and western Colombia. The broader taxonomic complex has also been associated with western Ecuador and north-western Peru, depending on the authority used.
What habitat does the Long-billed Hermit prefer?
It prefers humid lowland and foothill forest, forest edges, riverine vegetation and dense secondary growth. It may also use plantations, gardens and other modified habitats where flowering plants and cover are available.
What does the Long-billed Hermit eat?
Its diet consists mainly of nectar, supplemented by small insects and spiders. It commonly visits flowers along regular trap-lines rather than defending a single flower patch.
How can the Long-billed Hermit be identified?
Key features include its long, decurved bill, brownish-green plumage, dark facial mask, pale facial stripes and elongated central tail feathers with pale tips.
Does the Long-billed Hermit migrate?
It is generally considered resident. It may make local movements in response to flowering cycles and the availability of other food resources, but it is not known as a long-distance migrant.
Where can birdwatchers look for this species?
Good prospects include humid forest and secondary growth in protected areas such as the Área de Conservación Guanacaste and Refugio Nacional de Vida Silvestre Playa Hermosa-Punta Mala in Costa Rica, as well as suitable forest sectors of Parque Nacional Natural Paramillo in Colombia.
