Widespread but generally rare across much of northern South America. A medium-sized, plain brown woodcreeper with a bluish eye and limited white throat (sometimes nearly lacking). Completely unstreaked, so unlikely to be confused with anything but Plain-brown Woodcreeper, which has a stronger face pattern (especially a dark mustache) and lacks the bluish eye of White-chinned. Almost always seen near swarms of army ants, singly or in pairs. Occurs in lowland forest.
