Цейлонская масковая сипуха Phodilus assimilis

Small owl with immense dark eyes. Uncommon, strictly nocturnal, and very rarely seen. Listen for its odd squeaky whistles, “weeYEWWaweew,” delivered in series. Unmistakable if seen well: note heart-shaped face, richly-colored warm brown upperparts, and relatively clean underparts. A species of dense wet forests with thick undergrowth from lowlands up into hilly and montane areas.
