Habits: The Serendib Scops Owl is a secretive bird, roosting during the day mainly at low levels. It starts calling at dusk, but remains at roost until darkness falls.

Voice: The song of the male is a series of short, piping, tremulous notes of about 0.3 seconds duration, first slightly rising in pitch, then falling - wuhúwwo. These notes are repeated at intervals of up to 35 seconds. The female song is similar but slightly higher in pitch, and more tremulous.

Hunting & Food: This owl feeds mainly on insects such as moths and beetles, hunted from ground level to sub-canopy.

Breeding: The breeding biology of the Serendib Scops Owl is little known. Probably nests in tree cavities such as holes made by woodpeckers or barbets.

Habitat: Larger tracts of lowland rainforests from about 30-500m above sea-level. These areas are often secondary forests with dense undergrowth.

Distribution: Endemic to southwest Sri Lanka.
