Introduction
The Merida Sunangel, Heliangelus spencei, is a small hummingbird endemic to the Mérida Andes of north-western Venezuela. It inhabits humid montane forest, forest edges and shrubby high-elevation habitats, where it feeds mainly on nectar and supplements its diet with small arthropods.
Physical Description
The Merida Sunangel is a small to medium-sized hummingbird, measuring approximately 9–10 cm in length. Adults have dark green upperparts, a dusky crown, blackish ear-coverts and a conspicuous pale spot behind the eye. The underparts are pale greyish or yellowish, with green spotting and a noticeable white or buff band across the upper breast.
The male is distinguished by a glittering purple or pinkish-purple throat, which can appear darker or brighter depending on the light. Females are generally duller, with green upperparts and a buff or beige throat that may show some purple in the centre. As in other hummingbirds, the iridescent colours are produced by the structure of the feathers rather than by simple pigmentation.
Range and Habitat
The Merida Sunangel is endemic to Venezuela and has a restricted distribution in the Mérida Andes, particularly in Mérida state. It is a resident species rather than a long-distance migrant.
It occurs in humid montane forest, cloud-forest edges, bushy clearings, páramo margins and shrubby vegetation. Reported elevations vary across sources and localities, but the species is generally associated with elevations of roughly 1,900–3,600 metres. It may forage within forest vegetation as well as along edges and in areas where flowering shrubs are present.
The species has sometimes been treated as part of a wider Amethyst-throated Sunangel complex. Current major bird lists, including the IOC treatment, recognise Heliangelus spencei as a distinct species.
Where to See This Species
Sierra Nevada National Park, Mérida State, Venezuela
The species has been documented in Sierra Nevada National Park, including high-elevation trails in the Mérida Andes. Look for it in humid montane forest, forest edges and shrubby vegetation, particularly where flowering plants are present. Local conditions and access can vary, so birders should check current park regulations and use an experienced local guide where appropriate.
Nearby accommodation: Mérida is the main practical base, with hotels, guest houses, lodges and self-catering accommodation. Mountain settlements and villages near park access points may also provide simpler guest houses or cabins.
Sierra de La Culata National Park, Mérida State, Venezuela
La Culata is another protected area within the species’ restricted range. Museum records from the Culata area confirm the species’ presence, and the park’s humid montane forest, woodland edges and high-elevation shrub habitats provide suitable conditions for searching. Sightings may be localised, so careful observation around flowering vegetation is advisable.
Nearby accommodation: Mérida is the principal accommodation centre, with hotels, guest houses and self-catering options. Smaller settlements on routes into the park may offer basic rural lodging.
Behaviour and Diet
The Merida Sunangel is active during daylight hours and usually forages alone. It visits flowers on trees, shrubs and other montane plants, taking nectar with its long bill and extensible tongue. It also captures small insects and spiders, probably by making short sallies from a perch. These animal foods are especially important when feeding young.
Like other sunangels, it may hold its wings raised briefly after landing. Territorial behaviour and aggressive chases may occur around productive flowers or feeding stations, although detailed information on its social behaviour remains limited.
Breeding information is scarce. The known nest was a small, downy cup placed beneath an overhang on a small root in a road cut. It contained two white eggs and was found in June. The female is believed to undertake most or all nest construction and incubation, but the species’ full breeding cycle is not well documented.
Identification Tips
- Look for a small hummingbird with dark green upperparts, a pale spot behind the eye and a pale band across the upper breast.
- A male’s glittering purple throat is the most obvious feature, although the colour can appear dark, pinkish or violet depending on the viewing angle.
- Females have a much less vivid beige or buff throat and may show a small amount of purple centrally.
- The species is associated with humid montane forest and adjoining shrubbery in the Mérida Andes, usually at high elevations.
- Do not rely on throat colour alone. Compare the bird’s elevation, range, postocular spot, breast band and overall pattern with other Heliangelus species that occur locally.
Conservation Status
The Merida Sunangel is currently assessed as Least Concern on the IUCN Red List. Its population size and precise population trend are not well known, however, and its restricted range makes it vulnerable to local habitat changes.
The principal documented threats are the expansion of agriculture and the fragmentation of montane forest, including habitat changes within protected areas. Conservation priorities include maintaining connected forest and shrub habitats, protecting flowering plants, monitoring populations and improving knowledge of the species’ breeding ecology. Sierra Nevada and La Culata national parks provide important protected habitat within its range.
Frequently Asked Questions
Where is the Merida Sunangel found?
It is endemic to the Mérida Andes of north-western Venezuela, especially in Mérida state.
What habitat does the Merida Sunangel use?
It uses humid montane forest, cloud-forest edges, shrubby clearings and páramo margins, generally at elevations from about 1,900 to 3,600 metres.
What does the Merida Sunangel eat?
It feeds mainly on nectar from flowering plants and also takes small insects and spiders.
How can the male Merida Sunangel be identified?
The male has dark green upperparts, a pale spot behind the eye, a pale breast band and a glittering purple or pinkish-purple throat.
Is the Merida Sunangel migratory?
It is regarded as a resident species. There is no reliable evidence that it undertakes long-distance seasonal migration.
Is the Merida Sunangel threatened?
It is currently listed as Least Concern, but its small range is affected by agricultural expansion and habitat fragmentation. Its population trend remains poorly documented.
