White-tailed Emerald

Common name: White-tailed Emerald
Scientific name: Microchera chionura
Clades: Trochilini - Emeralds

The White-tailed Emerald is 7.5 to 8 cm (3.0 to 3.1 in) long. The males weigh about 3.3 g (0.12 oz) and the females 3.1 g (0.11 oz).

The White-tailed Emerald is a charming small hummingbird that captivates the eye with its splendid appearance. The male, adorned in shimmering emerald plumage, presents a striking contrast with its bright white lower belly and outer tail feathers. In comparison, the female possesses a similar allure, with white plumage extending up to the throat. Notably, both genders feature relatively short and subtly curved bills, adding to their distinctive characteristics.

In contrast, the Snowy-bellied Hummingbird offers a unique contrast with its coppery shoulders and rump, setting it apart from the White-tailed Emerald. The absence of white in its tail further distinguishes the Snowy-bellied Hummingbird from its emerald-hued counterpart.

These mesmerizing creatures can be found in the foothills of the Pacific slope, inhabiting elevations ranging from 800 to 2,200 meters. Their preferred habitats include humid or wet mountain forests, serene gardens, shaded coffee plantations, and old second-growth areas. It is within these diverse settings that the White-tailed Emerald graces observers with its presence, enchanting all who are fortunate enough to behold its exquisite beauty.

Endemic to Costa Rica and western Panama.
