Indian Scops-Owl

The Indian scops-owl (Otus bakkamoena) is a small nocturnal owl of the Indian subcontinent. Adults are about 20–22 cm long, have a wingspan of roughly 61–66 cm and weigh around 125–152 g. The plumage occurs in grey-brown and more rufous forms, both heavily mottled and streaked so that a resting bird can blend remarkably well with bark and dry foliage. Prominent ear tufts and a rounded facial disc give the species its characteristic appearance.

At a daytime roost, a bird pressed against a trunk or hidden among branches can be extremely difficult to detect until it opens its eyes or changes position.

Indian scops-owl belongs to a wider Asian scops-owl complex whose species boundaries have been debated for decades. Otus bakkamoena is currently recognised as a distinct species, but genetic and vocal patterns within the group do not always match the traditional boundaries neatly.

A study published in 2023 analysed territorial calls from 122 owls across Asia and found an unusual geographical pattern: populations at opposite ends of the wider complex sometimes sounded more alike than populations between them. The Indian scops-owl remains recognised as a distinct species, but the finding shows that the evolutionary history of these closely related owls is more complicated than their current names suggest.

Indian scops-owls use a broad range of tree-rich habitats, including deciduous and semi-evergreen forest, secondary woodland, groves, orchards, plantations and wooded areas around villages and towns. Dense foliage and tree cavities provide daytime roosts and nesting sites, while more open patches and edges create hunting opportunities.

Even in villages and towns, the species depends on tree cover. Mature trees and old cavities are valuable for both shelter and breeding, and wooded gardens or village groves can function as habitat where enough cover and feeding opportunities remain.

The diet is dominated by large insects and other invertebrates, although small lizards, rodents, occasional small birds and other vertebrates are also taken.

A pellet study published in 2002 at Auroville in southern India found a striking difference between two habitats: termites dominated in an older, wooded plantation, while grasshoppers and related insects dominated at a younger, grass-rich site. The contrast closely reflected local prey availability, showing how opportunistically the species feeds.

Hunting usually begins after dusk. The owl watches from a perch before dropping onto prey on the ground or in vegetation and can also make short flights to capture insects in the air. From such perches it can exploit both ground-dwelling prey and flying insects along woodland edges and openings.

Indian scops-owls are strongly nocturnal. During daylight they usually remain motionless in dense foliage, cavities or shaded branches, relying heavily on camouflage. Activity increases around dusk and continues through the night.

Territories are marked with low, regularly repeated calls after dark. These calls often reveal the owl's presence long before the bird itself is seen.

When disturbed at a daytime roost, a bird may stretch the body and compress the plumage, making its bark-like pattern even harder to pick out against a tree.

Pairs communicate with low calls and become more defensive around nest sites. Indian scops-owls nest in cavities, usually natural tree hollows or old holes made by other birds; sheltered cavities in buildings are also used locally. Clutches usually contain three to five white eggs. The female performs most of the incubation while the male supplies food, and both parents feed the young after hatching.

The species can also accept artificial nest sites. At Punjabi University in Patiala, a pair occupied a wooden nest box installed in a shisham tree. Two juveniles were recorded there in July 2018. The observation shows that nest boxes can be used, although natural cavities in mature trees remain the normal breeding sites.

The Indian scops-owl is classified as least concern on the IUCN Red List and remains widespread across much of the Indian subcontinent. It is considered locally common in suitable habitat, but its nocturnal behaviour and cryptic daytime roosting can make it easy to overlook even where it is common.

Loss of mature trees and nesting cavities can reduce local habitat, while pesticide use may affect the insect prey on which the species depends heavily. Its willingness to use orchards, plantations and wooded settlements gives it some flexibility, but retaining old trees and structurally varied vegetation remains important.
