Introduction
The Golden-tailed Sapphire (Chrysuronia oenone) is a small South American hummingbird of the family Trochilidae. It is recognised by its green plumage, iridescent blue or violet head and throat in males, and distinctive coppery-golden tail. The species occurs mainly in forest edges, secondary vegetation and other flower-rich habitats across the Amazonian region and the eastern foothills of the Andes.
Physical Description
The Golden-tailed Sapphire is approximately 9.5 to 10 cm long. Both sexes have a nearly straight black bill, green upperparts and a coppery-golden tail and uppertail coverts. The tail colour is usually more saturated in males.
Adult males are predominantly green, with a blue head in the nominate form and a violet or bluish-violet crown in some other geographic forms. The throat and breast may show iridescent blue-green tones. Females are less brightly coloured, with green upperparts and pale greyish underparts. Green spotting may extend along the sides of the throat, breast and belly.
Immature birds are generally less distinctive than adult males and may appear closer to the female pattern. Plumage intensity and head colour vary geographically, so the golden tail, black bill and overall green body are useful features when identifying the species.
Range and Habitat
The Golden-tailed Sapphire is distributed across parts of Colombia, Venezuela, Ecuador, Peru, Bolivia and western Brazil. It is generally resident rather than a long-distance migrant, although local movements may follow the availability of flowering plants.
The species is associated with forest edges, clearings, secondary vegetation, riverine growth and other semi-open habitats. It may also occur in shaded coffee and cacao plantations, gardens and flowering areas near forest. Records extend from lowland Amazonia into the eastern Andean foothills, commonly from about 280 to 1,550 metres, with some records reaching approximately 1,700 metres.
Two principal geographic forms are often recognised: C. o. oenone, found from eastern Colombia through eastern Ecuador and parts of north-eastern Peru and western Brazil, and C. o. josephinae, which occupies much of eastern Peru. The treatment of additional named forms varies between taxonomic authorities.
Where to See This Species
Waqanki Lodge, San Martín, Peru
Waqanki Lodge near Moyobamba is a practical place to look for the Golden-tailed Sapphire. The lodge is set within humid foothill forest and maintains flowering gardens and hummingbird-watching areas where the species has been recorded. Look around forest edges, gardens and feeding areas, particularly during the cooler morning period when hummingbirds are active.
Nearby accommodation: On-site lodge rooms and cabins are available, with additional guest houses and hotels in Moyobamba.
Amazonia Lodge, Cusco Region, Peru
The gardens and surrounding forest of Amazonia Lodge in the Manu foothills support a diverse hummingbird community, including the Golden-tailed Sapphire. The species is most likely around flowering plants, forest margins and secondary growth at the lower elevations reached from the lodge.
Nearby accommodation: On-site lodge accommodation provides cabins and rooms within the wildlife-viewing area.
Tambopata National Reserve, Madre de Dios, Peru
The Golden-tailed Sapphire has been recorded during organised birding visits to the Tambopata region, including around established rainforest lodges and trails. The best opportunities are in gardens, river-edge vegetation, secondary growth and forest clearings rather than in dense forest alone.
Nearby accommodation: Puerto Maldonado is the main gateway, while rainforest lodges and camps along the Tambopata River provide accommodation closer to the reserve.
Behaviour and Diet
Golden-tailed Sapphires are active, agile hummingbirds that usually forage alone. Males may defend productive flower patches or perches from other hummingbirds, although several individuals can gather where food is abundant. Their rapid wingbeats allow them to hover precisely while feeding and to make quick changes of direction.
Nectar forms the main part of the diet. The species visits a variety of flowering shrubs, trees and cultivated plants, and it may contribute to pollination as pollen is transferred between flowers during feeding. It also takes small insects and other arthropods, sometimes by making short sallies from a perch or by picking prey from foliage. These animal foods are particularly important during breeding and chick-rearing.
Breeding behaviour varies geographically. Males may perform aerial displays or gather in loose display areas to attract females. There is no lasting pair bond. The female builds the small cup-shaped nest, usually using plant fibres, moss and spider silk, and undertakes incubation and chick-rearing alone. Clutches normally contain two white eggs. Available accounts report an incubation period of about two weeks, with young remaining in the nest for several weeks after hatching.
Identification Tips
- Look for a small, mostly green hummingbird measuring about 10 cm.
- The coppery-golden tail and golden uppertail coverts are the most distinctive features in both sexes.
- Adult males show a blue or violet head and usually some iridescent colour on the throat and breast.
- Females are paler below, with variable green spotting on the throat, breast and belly.
- The bill is nearly straight and black.
- The species can be confused with other green hummingbirds, including the Rufous-throated Sapphire. The Golden-tailed Sapphire is distinguished by its black bill, green throat and breast pattern, and conspicuously coppery-golden tail.
- Check flowering shrubs, forest edges, secondary growth and garden plantings, where the bird may hover briefly before disappearing into cover.
Conservation Status
The Golden-tailed Sapphire is classified as Least Concern on the IUCN Red List. Its broad geographic range reduces the immediate risk of global extinction, although detailed population estimates are not available.
Habitat clearance, agricultural expansion and the gradual loss of flowering vegetation may affect local populations, especially where forest edges and secondary habitats are heavily modified. Maintaining native vegetation, protecting remaining forest and supporting sustainable land-use practices can help preserve the feeding and nesting habitats used by the species.
Frequently Asked Questions
Where is the Golden-tailed Sapphire found?
It occurs in parts of Colombia, Venezuela, Ecuador, Peru, Bolivia and western Brazil, mainly in Amazonian lowlands and the eastern foothills of the Andes.
How large is the Golden-tailed Sapphire?
It is approximately 9.5 to 10 cm long, making it a relatively small hummingbird.
What does the Golden-tailed Sapphire eat?
It feeds mainly on flower nectar and also takes small insects and other arthropods for protein and nutrients.
How can the Golden-tailed Sapphire be identified?
The combination of green plumage, a black nearly straight bill and a distinctive coppery-golden tail is the best starting point. Males also have a blue or violet head and iridescent throat.
Is the Golden-tailed Sapphire migratory?
It is generally considered resident. Local movements may occur in response to flowering cycles and changing food availability, but it is not known as a long-distance migrant.
What is the conservation status of the Golden-tailed Sapphire?
The species is listed as Least Concern. Even so, protecting forest edges, secondary vegetation and flowering habitats remains important for local populations.
