Sharp-billed Treehunter Heliobletus contaminatus

Small foliage-gleaner with a short pointed bill and long tail. Found in the canopy of montane forests including Araucaria forests where it acrobatically gleans epiphytic vegetation. Dark-brown on the back with a buffy-yellow eyebrow and collar, a heavily streaked breast, and a rufous tail. Usually follows mixed-species flocks. The song is a sharp, high rattle.
