Зондска врабчова кукумявка Taenioptynx sylvaticus

A tiny brown owl of humid forest in mountains and foothills, with brown upperparts and white underparts with long, broad rufous-brown streaks. Tooting song is variable, though the most common pattern is “doot doot-doot doot do-do-do,” repeated every 10-30 seconds. Often sings during the day, and can be mistaken for a barbet, but the exact pattern of toots is unlike any barbet. Visually, could be mistaken for a scops-owl, but separated by the distinctive voice, the broad brown streaks below, and the lack of ear tufts.
