Crowned Woodnymph

Identification

The crowned woodnymph is a small hummingbird, with males measuring 9.5 to 11.5 cm and females slightly smaller at 8.5 to 9.2 cm. The species is remarkably sexually dimorphic. Males of the nominate subspecies display striking violet plumage on the forehead, crown, upper back, and belly, contrasted with a dark bronzy-green nape and glittering green throat and chest. Their deeply forked tail is blue-black. Females present a more subtle appearance with bright green upperparts, pale gray throat and chest, and a darker gray belly, while their blue-black tail features distinctive white tips on the outer three pairs of feathers. Immature birds show duller coloration with less iridescent plumage than adults.

Given the species' seven recognized subspecies distributed across Central and South America, plumage varies geographically. Some males lack the violet crown entirely, replacing it with glittering green, while others show variations in nape coloration from bronze to blue-green and differences in belly patterns. These subspecific variations can make field identification challenging for travellers unfamiliar with regional populations.

Range & Habitat

The crowned woodnymph is found from Belize and Guatemala south to far-northern Peru, with seven subspecies occupying distinct ranges. The species inhabits the interior, edges, and clearings of humid primary and mature secondary forests, as well as semi-open landscapes such as coffee and cacao plantations and gardens. It notably avoids open scrublands, preferring areas with forest cover or partial shade.

Elevation varies considerably across the bird's range. In Costa Rica, breeding occurs between sea level and 900 m, with post-breeding movements reaching 1,200 m. In Colombia and Venezuela, breeding takes place between 1,600 and 2,000 m, while in Peru the species breeds only up to 950 m. The woodnymph also moves locally to follow flowering events, making its presence somewhat unpredictable without knowledge of seasonal flowering patterns.

Behaviour & Diet

The crowned woodnymph is primarily nectarivorous, feeding on nectar from a variety of flowering plants at epiphytes, herbs, shrubs, and small trees, typically in covered or semi-open areas rather than exposed locations. Interestingly, males and females exhibit different foraging strategies during breeding season, with males preferring the canopy and females the understory, though both exploit all levels outside the breeding period. The species supplements its diet with small arthropods captured through hawking from perches or gleaning from foliage, with females engaging in gleaning more frequently than males.

Territorial behaviour differs markedly between sexes. Both males and females defend rich nectar sources, but females are notably more aggressive in territory defence. Their territories also experience higher rates of intrusion and produce greater mean nectar volumes. Breeding seasons vary dramatically across the species' range, from February to June in Costa Rica to almost any part of the year in southwestern Colombia. The woodnymph builds a delicate cup nest from treefern scales and plant down bound with spiderweb, typically placing it on a horizontal twig under a leaf, usually within 5 m of the ground, and lays a clutch of two eggs.

Best Time & Places to See It

Travellers seeking crowned woodnymphs should time visits to local breeding seasons, which vary by region: February to June in Costa Rica, March in Panama, and February to September in Colombia. The species is most reliably found in humid forests with flowering understory plants rather than open areas. Look in forest edges, clearings, and semi-open landscapes such as well-vegetated gardens and coffee plantations where flowering nectar sources are abundant.

Since the woodnymph's presence depends partly on flowering events, inquiring locally about recent flowering patterns will improve sighting chances. The species' preference for covered and semi-open foraging areas means that birds are often visible from ground level and nearby perches, making it more accessible to photographers than canopy-dwelling hummingbirds, particularly when females are foraging in the understory during breeding season.

Photography Tips

Photographing crowned woodnymphs presents both challenges and opportunities. The males' iridescent violet and green plumage requires careful lighting to capture the full spectacle of their metallic colours, which shift dramatically with angle and light direction. Position yourself to maximize side-lighting that will illuminate these iridescent feathers. The species' preference for semi-open and covered areas, while good for visibility, may result in dappled lighting conditions that complicate exposure metering.

The deeply forked tail and small, rapidly-moving form demand fast shutter speeds, ideally 1/2000 second or faster. Since females forage in the understory more than males, concentrate efforts in lower vegetation layers during breeding season for improved access. The woodnymph's territorial behaviour can be advantageous—birds defending rich nectar sources tend to return repeatedly to favoured flowers, allowing photographers to set up and anticipate their visits. Early morning light often provides the clearest conditions and most vibrant colour rendition in tropical forest settings.
