Orange-bellied Euphonia

Overview

The orange-bellied euphonia (Euphonia xanthogaster) is a small songbird belonging to the family Fringillidae, which includes finches and euphonias. This species is found across parts of South and Central America and is currently classified as Least Concern on the IUCN Red List.

Identification

• Size 9 to 11 cm in length with a thick, stubby bill.
• Sexually dimorphic: adult males feature glossy blue-black upperparts, a deep yellow forehead, and a purplish-black throat, while females are predominantly olive with grey underparts.
• Song varies by region; in Ecuador it is described as a variable, almost random-sounding series of semimusical phrases, whereas in Colombia and Venezuela it is a rambling, disconnected series of syllables like 'deeu deeu...deet deet'.

Habitat

Found in a disjunct range across Bolivia, Brazil, Colombia, Ecuador, Guyana, Panama, Peru, and Venezuela, the species generally inhabits humid to wet evergreen forests, including canopy, edges, and clearings. In the Andes it occupies foothill forests up to montane cloud forest, while in the Amazon it lives in both várzea and terra firme forest, typically ranging in elevation from sea level to 2,300 m.

Diet

Feeds primarily on small fruits, supplementing its diet with smaller amounts of arthropods. It mostly forages in pairs and regularly joins mixed-species feeding flocks, operating primarily in the mid-level to canopy but often descending to the shrub layer in clearings and edges.

Did you know?

The 'black-throated euphonia' (Euphonia vittata) was originally described as a separate species but is now believed to be a hybrid between the orange-bellied euphonia and the chestnut-bellied euphonia.
