Formicivora melanogaster
The Black-bellied Antwren (*Formicivora melanogaster*) is a diminutive yet striking member of the antbird family (Thamnophilidae), endemic to the dry savannas and scrublands of South America. Measuring approximately 11-13 cm in length and weighing a mere 9-12 grams, this species exhibits pronounced sexual dimorphism, making identification straightforward. Males boast a glossy black belly, throat, and face, contrasting sharply with a white supercilium and grayish-brown upperparts accented by t...
Primarily inhabits dry savannas, Cerrado grasslands, and shrubby semi-arid woodlands, preferring areas with dense undergrowth. Typically found at low to moderate elevations, generally below 1200 meters.
Feeds primarily on small arthropods, including insects such as grasshoppers, beetles, caterpillars, and spiders. Forages by gleaning prey from foliage, twigs, and bark, typically within dense undergrowth.
Black-bellied Antwrens are diurnal and highly active, spending their days foraging low in vegetation. They employ a strategy of active gleaning, hopping through dense shrubs and small trees, carefully scrutinizing leaves and twigs for insect prey. This species is typically encountered in monogamo...
