Wing-banded Wren is a tiny songbird with a big voice of northern South America, mainly east of the Andes. Its range includes parts of Venezuela, the Guianas, Brazil, Ecuador, and Peru. This is a small, short-tailed wren that is dark brown above and gray below with blackish wings marked with a single white bar. The species seems to be closely related to the mostly allopatric Scaly-breasted Wren, but is visually distinctive due to the white wing bar. Wing-banded Wren even sounds like Scaly-breasted Wren with a high series of notes that becomes more rapid toward the end of the song.
