Assez commun et répandu dans une grande partie de l'Amérique du Sud. Le mâle se distingue par sa gorge blanche, sa calotte noire bien définie, son dos et ses ailes noirs et son ventre grisâtre. Les pattes sont rouge-orange vif. Les femelles sont d'un olive plus terne avec un ventre plus pâle. Les pattes rouges permettent de les distinguer des autres manakins femelles. Comme la plupart des manakins, il est assez dodu, avec une queue et un bec plutôt courts. Les mâles se rassemblent sur des sites de présentation dans le sous-bois de la forêt, où ils font de grands bruits de claquement d'ailes. Il faut également écouter le cri descendant "peew". Loin des sites de présentation, ils sont plutôt discrets et se rencontrent généralement seuls, souvent autour d'un arbre fruitier.
Habitats et répartition
The White-bearded Manakin inhabits the tropical forests and secondary growth woodlands across its geographical range. It thrives in humid lowland forests, forest edges, and areas with dense understory, often being found near water sources such as streams and rivers. This bird species displays a preference for environments abundant with fruiting trees and shrubs, which supply its primary food source. Geographically, the White-bearded Manakin is distributed across a vast region in Central and South America, spanning from southern Mexico through Panama, and extending into the northern reaches of South America, including Colombia, Venezuela, the Guianas, Peru, Brazil, and Bolivia. This range underscores its adaptability to diverse tropical and subtropical habitats, where it can exploit various ecological niches for foraging and breeding.
Comportements et reproduction
Male White-bearded Manakins are known for their elaborate courtship displays, which are essential for attracting females. They perform acrobatic displays in leks, where multiple males gather to compete for female attention. These displays involve rapid, mechanical-sounding wing snaps, flips, and quick dashes between perches, creating a visually and audibly striking performance. Females visit these leks to select a mate based on the vigor and skill of the males' displays. The social structure of White-bearded Manakins is highly polygynous, with dominant males, often older and more experienced, securing the most matings. After mating, females take on the responsibility of nest building and raising the young alone. The nests are typically small, cup-shaped, and constructed from plant fibers and leaves, usually placed in shrubs or low trees. This reproductive strategy allows males to maximize their mating opportunities while females ensure the survival of their offspring through solitary parental care.
Régime alimentaire
Le manakin à barbe blanche se nourrit principalement de petits fruits. Il consomme également des insectes tels que des coléoptères, des mouches et des termites volants.

Faits amusants
Au moment de la reproduction, les mâles se livrent à des parades sur le sol de la forêt, au cours desquelles ils gonflent les plumes de leur cou.
Statut de conservation et efforts
The White-bearded Manakin (Manacus manacus) is currently classified as of "Least Concern" by the International Union for Conservation of Nature (IUCN), indicating that it is not at immediate risk of widespread decline. Population trends are considered stable, though habitat degradation poses a potential threat. This species inhabits a range of forested environments across South and Central America, which provides some resilience against localized habitat loss. Conservation efforts for the White-bearded Manakin primarily focus on habitat protection and management. The maintenance and expansion of protected areas within its range are crucial in safeguarding its environment. Additionally, programs aimed at reforesting and rehabilitating degraded areas support the preservation of suitable habitats. Monitoring population trends and habitat quality continues to be essential to ensure that potential threats do not escalate to endanger this species.
