Slender, long-tailed antbird restricted to Colombia’s eastern Andes. Note the profuse streaking on foreparts and the orange belly and rump. Male’s streaks are darker and more contrasting than female’s. Similar to Klages's Antbird (little or no overlap), but central underparts are streaked instead of plain. Also very similar to Streak-headed Antbird and Santa Marta Antbird, but no range overlap. Inhabits bamboo thickets in cloud forest. Song consists of a few clucking notes followed by several rasps.
