Merulaxis ater
The enigmatic Slaty Bristlefront (Merulaxis ater) is a medium-sized tapaculo, measuring approximately 18.5 to 20 cm (7.3-7.9 inches) in length and weighing between 42 to 50 grams. Males exhibit a striking glossy dark slate-gray to blackish plumage, while females are slightly duller, appearing brownish-black, making sexual dimorphism subtle but present. Its most distinctive feature is the prominent crown of stiff, bristle-like feathers on its forehead, giving the genus its unique name and aidi...
This reclusive species inhabits the dense undergrowth of humid evergreen forests in the Atlantic Forest biome, typically found at elevations ranging from 100 to 1,000 meters above sea level.
Its diet consists primarily of small invertebrates, including insects and spiders, which it forages for by gleaning and probing through leaf litter on the forest floor.
Exceedingly secretive and largely terrestrial, the Slaty Bristlefront spends its days rummaging through leaf litter on the forest floor, searching for invertebrates. Its daily activity is diurnal, though it remains hidden within dense vegetation, making visual observation rare. The species is tho...
The Slaty Bristlefront is endemic to the Atlantic Forest biome of southeastern Brazil, with its primary range extending from southeastern Minas Gerais and Espírito Santo south through Rio de Janeiro, São Paulo, Paraná, and Santa Catarina. Isolated populations also exist further south, and unconfi...
