Wing-banded Wren

The wing-banded wren is 11.5 cm (4.5 in) long and weighs 17 to 19 g (0.60 to 0.67 oz). Adults of the nominate subspecies have a blackish-brown crown, upperparts, and tail. The upperparts have obscure dusky markings and the tail has obscure darker brown bars. Its dark chocolate-brown wing shows a broad white band when closed. It face is dark brown, the chin and throat gray, the chest gray-brown with dark tips on the feathers, and the belly and flanks a purer brown than the chest. The belly and flanks have faint bars. The juvenile's underparts appear scaly and it does not have the white wingbar. Voice: The wing-banded wren's song is "a beautiful series of 3–6 clear, pure high-pitched notes separated by short pauses", sometimes extended by a "long, sustained glissando". Its call note is "a sharp metallic 'click'".
