Species Overview

The Violet-capped Woodnymph is a widespread and unmistakable hummingbird of Brazil’s Atlantic Forest and its southern neighbors. Males are dazzling with a deep violet crown, glittering green throat and chest, and bluish tail. Females are less vibrant but still elegant, with a bluish-green back and pale gray underparts.

This species is known for its agility and boldness, often dominating feeders and flowering trees. It adapts well to human-modified environments and is frequently found in city parks, gardens, and suburban areas.

Male Description:

The male displays a rich violet crown that sharply contrasts with a shiny emerald-green body. The belly is dark bluish-green, and the tail is forked and deep blue. The bill is medium-length, straight, and black.

Female Description:

Females lack the male’s violet crown. Their upperparts are metallic green, while the underparts are pale gray with greenish flanks. The tail is bluish with white tips, slightly notched.

Habitat & Behavior:

Active in open woodlands, urban green areas, and forest edges, this species is highly adaptable. Males often defend flower patches, particularly in disturbed habitats. Forages at various heights, usually favoring mid-level blooms and occasionally hawking insects. Courtship displays are aerial and include rapid vertical ascents and dives.

Conservation Note:

Although restricted to southeastern South America, the Violet-capped Woodnymph remains common across its range. It benefits from its ability to thrive in fragmented habitats, including urban zones. Continued habitat loss in the Atlantic Forest region is a concern, but this species is currently not considered at risk.
