The Versicolored barbet (*Eubucco versicolor*) is a dazzling, small bird endemic to the Andean cloud forests of Peru and Bolivia, renowned for its vivid, rainbow-like plumage. Males boast a striking combination of a crimson crown, yellow nape, blue cheeks, and a green back, while females are more subtly patterned with a black-banded yellow throat and olive hues, making them one of the most sexually dimorphic barbet species. With a stout, ivory-colored bill adapted for plucking fruit, its special feature is a high-pitched, repetitive call that echoes through the canopy, and its preference for feeding on mistletoe berries plays a vital ecological role as a seed disperser.

Faits amusants

The male versicolored barbet sports a kaleidoscopic head pattern of red, yellow, blue, and green that shifts depending on the angle of light, a trait rarely seen in other barbets. It often engages in a peculiar "head-bobbing" display during courtship, where both birds rapidly dip and raise their heads in near-perfect synchronization. Unlike most barbets, which are solitary nesters, this species occasionally tolerates a helper—usually a previous year’s offspring—that assists with feeding chicks, a rare example of cooperative breeding among New World barbets. Its tongue is tipped with brush-like bristles, an adaptation for efficiently lapping up fruit pulp and nectar, making it a key pollinator for certain Andean mistletoes.

Habitats et répartition

This barbet inhabits humid montane forests and cloud forests on the eastern slopes of the Andes, typically at elevations between 600 and 2,000 meters. It prefers dense, mossy canopy in primary forest but may also occur in adjacent mature secondary growth. Its geographical range extends from central Peru south through the Yungas of Bolivia, with isolated populations possibly reaching extreme southeastern Ecuador.

Comportements & Reproduction

Pairs are monogamous during breeding, with both sexes actively defending a territory. Outside the nesting season, they are often observed in small family groups or joining mixed-species foraging flocks, indicating a degree of social flexibility. Courtship includes vocal duets and mutual feeding. For reproduction, they excavate nest cavities in dead wood, bamboo, or even termite mounds, typically placing the entrance 2–3 meters high. The clutch consists of 2–3 white eggs, and both parents share incubation for about two weeks. After hatching, both adults feed the chicks a diet of fruit and insects. A notable strategy is their use of soft, decaying wood or termite structures for cavity excavation, which reduces the energy required for digging. The young remain with the parents for a period after fledging, but no cooperative breeding or helper system has been documented in this species.

Alimentation

The Versicolored barbet is primarily frugivorous, with fruits—especially those from the mistletoe family (Loranthaceae) and various tropical trees—making up the bulk of its diet. It uses its stout, bristly bill to pluck berries and small fruits directly from branches, often hanging upside down to reach them. Interestingly, this barbet also supplements its diet with a variety of arthropods, including insects, spiders, and caterpillars, which it gleans from foliage or catches in short, acrobatic sallies. It has been observed to consume the petals and nectar of certain flowers as well, and it plays a key role in seed dispersal by regurgitating the seeds of the fruits it eats, particularly benefiting mistletoe plants.

Couleurs

The Versicolored barbet exhibits striking sexual dimorphism: males have a bright red crown and nape, a yellow throat, a blue band across the upper breast, and green upperparts with red and yellow streaks on the wings; females are duller with olive-green heads, yellow throats, and less vivid blue and red patches. Both sexes have a black eyestripe and a stout, pale bill. This vivid, fragmented coloration serves more for display than camouflage, though the green upperparts provide some concealment in foliage.
