Introduction
The Veraguan Mango, Anthracothorax veraguensis, is a medium-sized hummingbird of the Pacific lowlands of western Panama and adjacent south-western Costa Rica. It is a near-endemic of the South Central American Pacific slope and is associated with flowering woodland, forest edges, mangroves, open country and well-treed rural landscapes.
Physical Description
The Veraguan Mango measures approximately 10 to 12 centimetres in length. It has a slightly decurved, dark bill, metallic green upperparts and dark wings. The tail is predominantly dark with maroon, purplish or bronzy tones, depending on the angle of the light.
Adult males have green to blue-green underparts, with the bluest colour usually concentrated on the throat, chest and central belly. Unlike the Green-breasted Mango, the Veraguan Mango generally lacks a broad black throat and central underparts. Small white feather tufts are often visible on the flanks.
Adult females are more contrastingly patterned. They have metallic green upperparts, pale underparts and a greenish-blue central stripe extending from the throat down the breast and belly. The outer tail feathers commonly show pale or white tips. Immature birds resemble females, although young males may gradually develop the richer blue-green plumage of adults. Plumage variation occurs, and occasional females with male-like plumage have been documented.
Range and Habitat
The Veraguan Mango is found mainly in western Panama, from Chiriquí eastwards to southern Coclé, with records from nearby Pacific islands. It also occurs in the southern Pacific lowlands of Costa Rica, although identification of some Costa Rican birds has historically been difficult because of their similarity to the Green-breasted Mango.
It favours relatively open lowland habitats rather than dense, closed-canopy forest. Suitable sites include forest margins, secondary woodland, mangroves, flowering trees, gardens, plantations and open areas with scattered trees. It is generally a lowland species, and most observations come from warm Pacific-slope habitats at low elevation.
The species is regarded as resident, although individuals may move locally in response to flowering and food availability. It is not considered a long-distance migrant.
Where to See This Species
Golfo de Montijo Wetland and the Pacific Coast of Veraguas, Veraguas, Panama
The Pacific coast of Veraguas is one of the most reliable regions for this near-endemic hummingbird. The surrounding lowland woodland, wetlands, mangroves and flowering rural landscapes provide suitable habitat, and the species is specifically reported from the region. Look for it around flowering trees and forest edges rather than in dense wetland vegetation alone.
Nearby accommodation: Santiago is the main practical service town, while coastal settlements near Montijo and Santa Catalina provide guest houses, small hotels, lodges and self-catering accommodation.
Juan Hombrón and El Chiru, Coclé, Panama
The open landscapes, wetlands, mangroves and scattered flowering trees around Juan Hombrón and El Chiru are documented birdwatching areas for the Veraguan Mango. These sites are particularly suitable for watching hummingbirds in open country, along roadsides and around flowering trees. The species may be easier to locate during periods of active flowering.
Nearby accommodation: Penonomé, Río Hato and the coastal accommodation areas around Farallón provide hotels, guest houses, lodges and self-catering options.
Piedras Blancas National Park and La Gamba, Puntarenas, Costa Rica
Piedras Blancas National Park and the nearby La Gamba area represent one of the better-documented Costa Rican locations for the species. Sightings have been recorded along the park entrance road and around flowering plants near the Tropical Research Station. Identification should be made carefully because Green-breasted Mangoes also occur in the region and the two species can be difficult to separate.
Nearby accommodation: La Gamba and Golfito provide practical bases with lodges, guest houses, small hotels and other visitor accommodation.
Behaviour and Diet
The Veraguan Mango is active by day and spends much of its time moving rapidly between flowering trees, shrubs and other nectar sources. Like other hummingbirds, it can hover while feeding and manoeuvre quickly through vegetation.
Nectar is an important food source, and the species has been observed visiting flowers such as heliconias and erythrina trees. It also takes small insects and spiders, particularly when additional protein is needed. By carrying pollen between flowers, it contributes to the pollination of many tropical plants.
Individuals may defend productive flowering plants or feeding territories, and males can be aggressive towards other hummingbirds and intruders. Courtship displays and territorial chases may include rapid flight, hovering and vocal calls. Detailed information on nesting and breeding remains limited, so the exact timing of breeding across the range should not be assumed to be uniform.
Identification Tips
- Look for a medium-sized hummingbird with a long, slightly curved dark bill and metallic green upperparts.
- The adult male usually shows green to blue-green underparts and a dark, maroon or purplish tail, without the broad black throat and belly typical of the Green-breasted Mango.
- The female is more distinctive when seen well, with pale underparts crossed by a greenish-blue central stripe and pale-tipped outer tail feathers.
- Check the habitat. Veraguan Mango is especially associated with lowland Pacific-slope woodland, forest edges, mangroves, gardens and flowering trees.
- Separate it from the Green-breasted Mango with caution. Lighting can alter the apparent colour of the throat and breast, and females or immature birds may be particularly difficult to identify.
- Some females may show unusually male-like plumage, so sex should not be assigned solely from a brief view of colour.
Conservation Status
The Veraguan Mango is currently assessed as Least Concern on the IUCN Red List. Its population size and precise population trend are not well documented, and the species has a relatively restricted distribution concentrated in the Pacific lowlands of Panama and adjacent Costa Rica.
The principal potential threats are the loss and fragmentation of lowland woodland, mangroves and forest edges through agricultural expansion, urban development and other land-use changes. Changes in flowering patterns, prolonged drought and pesticide use may also affect nectar supplies and the insects taken as supplementary food. Protecting Pacific-slope forests, wetlands, mangroves and flowering corridors is important, particularly in areas where the species has a narrow geographic range.
Frequently Asked Questions
Where is the Veraguan Mango found?
It occurs mainly in western Panama, from Chiriquí to southern Coclé, and in adjacent Pacific lowlands of southern Costa Rica.
Is the Veraguan Mango endemic to Panama?
It was historically treated as a Panamanian endemic, but it is now also documented from south-western Costa Rica. It is therefore best described as a near-endemic of the Pacific slope of southern Central America.
What does a male Veraguan Mango look like?
The male has metallic green upperparts, blue-green underparts and a dark tail with maroon or purplish tones. It generally lacks the broad black throat and belly of the Green-breasted Mango.
What does a female Veraguan Mango look like?
The female has green upperparts, pale underparts and a greenish-blue central stripe running down the throat, breast and belly. Pale tips on the outer tail feathers are often visible.
What does the Veraguan Mango eat?
It feeds mainly on nectar from flowering plants and supplements this diet with small insects and spiders.
Is the Veraguan Mango endangered?
The species is currently classified as Least Concern by the IUCN. Nevertheless, habitat loss and degradation remain important concerns because much of its range is concentrated in lowland Pacific habitats.
