The Buff-fronted Foliage-gleaner exhibits perhaps the most unusual geographical range of any Philydor species, it being distributed, sometimes locally, from the highlands of Costa Rica south to northern South America, and through the tropical Andes as far south as central Bolivia, with a disjunct population across south-central Brazil to eastern Paraguay and northeast Argentina. In the Atlantic Forest, the Buff-fronted Foliage-gleaner could be confused with the very morphologically similar Ochre-breasted Foliage-gleaner (Philydor lichtensteini), but elsewhere the present species should be easily identified by its largely grayish upperparts, which contrast strongly with the reddish-brown wings and tail; not all populations (some seven subspecies are traditionally recognized) possess an obvious buff forehead patch. The Buff-fronted Foliage-gleaner is generally common, and is most usually encountered within mixed-species flocks of insectivores. Source: http://bit.ly/1fYp2sf. http://bit.ly/PUASK9
