Euphonia rufiventris
The Rufous-bellied Euphonia (Euphonia rufiventris) is a striking passerine bird, a member of the finch family (Fringillidae), though historically often grouped with tanagers. Males are instantly recognizable by their glossy purplish-black upperparts and a vivid, contrasting rufous-orange belly, throat, and undertail coverts, often accented by a small yellow patch on the forecrown. They typically measure around 10-11 cm (4-4.3 inches) in length and weigh 10-15 grams. Females are more subtly ad...
Found primarily in the canopy and subcanopy of humid evergreen tropical lowland and foothill forests, extending into degraded secondary growth. It typically occurs at elevations from sea level up to 1200-1400 meters, occasionally higher.
Primarily frugivorous, with a strong preference for small berries, especially those of mistletoe (Loranthaceae). They also supplement their diet with small insects and spiders, typically gleaned from leaves and branches.
Rufous-bellied Euphonias are diurnal, typically active from dawn to dusk, often foraging high in the forest canopy. They usually move in pairs or small family groups, though they may occasionally join mixed-species foraging flocks, particularly those led by tanagers. Their foraging strategy prima...
The Rufous-bellied Euphonia boasts a wide and stable distribution across the western and central Amazon Basin of South America. Its breeding and resident range extends from southern Colombia, through eastern Ecuador and eastern Peru, into northern Bolivia. Eastward, it occupies significant portio...
Least Concern
- The Rufous-bellied Euphonia was once classified with tanagers (Thraupidae) but is now firmly placed within the finch family (Fringillidae), highlighting the complex evolutionary relationships among passerine birds. - Its diet relies heavily on mistletoe berries, making it a crucial seed dispers...
