It occurs in humid tropical and subtropical forests, and coastal restinga (stunted forests on white sands) with dense understorey of shrubs and vines; mainly below 200 m. A small, short-tailed antwren (length 9-10 cm; weight 6.5-8.5 g). The male is uniform gray with a black-spotted throat; the female is brown-gray with a rufescent tail. This species breeds in October-December. The nest is cup of dead leaves, roots and filaments placed in a horizontal fork 0.8-2 m above the ground. Unicolored Antwren feeds on small insects and spiders, and frequently joins mixed-species flocks, e.g., with the Silvery-flanked Antwren.
