The Streak-crowned Antvireo inhabits the Atlantic Slope of southeast Honduras, Nicaragua and Costa Rica. The male Streak-crowned Antvireo has a dark gray crown streaked with grayish-white, grayish-olive upperparts, a white throat and breast with contrasting dark streaks and yellowish underparts. Females have a dark spotted rufous crown and an ocher colored breast and flanks. The bold streaking on the male Streak-crowned Antvireo’s crown and breast allows it to be distinguished from the similar Plain Antvireo (Dysithamnus mentalis). Streak-crowned Antvireos are most often encountered as members of mixed species flocks of woodcreepers, antwens and greenlets. When foraging, the Streak-crowned Antvireo hops deliberately through foliage, pausing occasionally to scan for prey or to make a short sally to the underside of an overhanging leaf.
