Oriental Scops-owl
Appearance
The Oriental Scops-owl is a small owl with prominent ear tufts and large yellow eyes. Its plumage is primarily mottled brown and grey, providing excellent camouflage against tree bark. The underparts are lighter, with fine dark streaks and bars.
There is little difference between males and females. Some individuals display a rufous morph, while others exhibit a grey morph. Juveniles resemble adults but may have a slightly fluffier and less vivid appearance.

Distribution
Oriental Scops-owls inhabit a wide range of wooded habitats, including deciduous and evergreen forests, woodland edges, and plantations. They are found across much of South and Southeast Asia, from India and southern China to Indonesia.
During winter, some northern populations migrate southward, while others remain resident year-round.
They may occasionally be spotted as vagrants in extreme western Alaska (Aleutian Islands). There have only been two confirmed recorded sightings, though, in 1977 and 1979.

Diet
The Oriental Scops-owl primarily feeds on insects, including moths, beetles, and grasshoppers. They also consume small vertebrates such as mice, lizards, and small birds.
These owls hunt by swooping down from perches to catch prey on the ground or in flight.
Behaviour
Oriental Scops-owls are primarily nocturnal, roosting during the day in dense foliage or tree cavities. They hunt from perches, swooping down to catch prey on the ground or in mid-air.
These owls are generally solitary but may form loose pairs during the breeding season.
Vocalisation
The Oriental Scops-owl's call is a distinctive, repetitive 'poop-poop-poop' or 'whoop-whoop-whoop', typically given at regular intervals.
During the breeding season, males may call frequently throughout the night. They also produce soft trills and whistles for close communication.
Nesting & Breeding
Breeding season for Oriental Scops-owls typically occurs from March to June but can vary slightly depending on the range. Males attract females with their distinctive calls, and pairs form monogamous bonds for the breeding season.
These owls nest in tree cavities, often using abandoned woodpecker holes or natural hollows. The female lays 3-5 white, roundish eggs directly on the cavity floor without building a nest.
Incubation lasts about 25 days, and it is primarily done by the female while the male provides food. Chicks fledge after 21-25 days but remain dependent on their parents for several weeks.
Lifespan
years
The Oriental Scops-owl typically lives for 3 to 10 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Conservation and Status
Global Conservation Status
While the Oriental Scops-owl is currently listed as Least Concern, it faces threats from habitat loss due to deforestation.
Conservation efforts focus on preserving its woodland habitats and monitoring population trends across its range.
Birdwatching Tips
- Listen for their distinctive 'poop-poop-poop' call at night
- Look for them perched motionless in dense foliage during the day
- Use a spotlight at night to catch the reflection of their eyes
- Check tree cavities and old woodpecker holes in forested areas
