Species Overview

The Blue-tailed Hummingbird is a vivid, medium-sized species common along humid foothills and forest edges in Central America. Its glowing emerald plumage and sapphire-blue tail make it one of the region’s most eye-catching hummingbirds. Frequently seen at forest clearings and gardens, it is both territorial and remarkably adaptable to human-altered landscapes.

Male Description:
The male has brilliant metallic green upperparts and underparts, a deep blue tail, and a slightly decurved black bill. The underparts sometimes show a subtle bronze sheen. The tail and rump gleam an intense cobalt-blue in sunlight, creating a sharp contrast against the emerald body.

Female Description:
The female is similar but has paler underparts, a bluish-green tail tipped with grayish-white, and a slightly shorter bill. Her plumage is less intensely iridescent, especially on the underparts.

Habitat & Behavior:
The Blue-tailed Hummingbird inhabits humid and semi-humid forest borders, coffee plantations, gardens, and secondary growth, often at mid-elevations. It feeds on nectar from Inga, Hamelia, and Heliconia flowers, also catching small insects mid-air. Males are territorial, frequently engaging in short aerial chases. Its call is a sharp tsip-tsip, and its flight is fast, with quick hovering between flowers.

Conservation Note:
The Blue-tailed Hummingbird is classified as Least Concern by the IUCN and remains widespread and locally common across its range. Its tolerance for disturbed and cultivated habitats contributes to its stability, though localized declines occur where forest clearing and pesticide use reduce nectar sources. Maintaining flower-rich edges and shade-grown agroforestry systems is vital for preserving this striking Trochilini species.
