Violet-capped hummingbird

The violet-capped hummingbird (Goldmania violiceps) is a species of hummingbird in the family Trochilidae. It is found in Panama and far northwestern Colombia.

Its natural habitat is subtropical or tropical moist lowland forest. It is found mostly from 2,000 to 4,000 feet in elevation.

Description

This hummingbird is 3.5 inches in length. Males may be identified by the combination of violet crown and forked chestnut tail. The female is the only hummingbird in its range with the combination of mostly white underparts and chestnut tail.

The Violet-capped Hummingbird is endemic to eastern Panama and extreme northwestern Colombia, where it is found in humid forest and forest edge in foothills and on mountain slopes. It is largely bright green, with an iridescent violet crown and bright red bill commisure. The female is dull grayish below. It feeds on flowers at lower forest strata, but there is little additional information on behavior.

8·5–9·5 cm; male 3·8–4·4 g, female 3·4–3·9 g . Male has straight black bill, mandible basally flesh-coloured; crown iridescent violet-blue; back and underparts metallic green; undertail-coverts green, with central feathers white and stiffened; tail slightly forked, maroon, broadly bordered with bronze; white femoral tufts.
