A uniquely-marked little Furnariid. Very uncommon in restricted range on the west slope of the Andes in Colombia and Ecuador. Mostly bright orange-rufous with a dazzling white throat that bleeds down into bold speckles on upper breast. Singles or pairs forage with mixed-species flocks, usually hitching along mossy branches in the middle to upper levels. Occurs in humid mossy forest from around 1,200–2,200 m, typically at lower elevations than Pearled Treerunner.
