A small buffy-brown wren with a very limited range in central Colombia. Look for a streaked back and dark barring on the wings and tail. Compared with Sedge Wren, Apolinar’s has a grayer throat and eyebrow. Found in marshes with tall cattails and sedges from around 2,000 to 3,500 m. Can be skulking and difficult to see, but occasionally perches up to sing. Listen for strange harsh chirring song.
