The mottled wood owl (Strix ocellata ) is a species of large owl found in India. They are found in gardens and thin deciduous forests adjacent to dry thorn forests or farmland. They are easily detected by their distinctive tremulous eerie calls at dawn and dusk. The characteristic call is a duet of the male and female while other notes include a low hoot and a screech. Their large size, lack of "ear" tufts and the concentric barring on the face make them easy to identify.
The eerie call has been associated with ill omen in some parts of Kerala. The call is interpreted as povaa-aa (="let us go" in Malayalam) and likened to a summons to the spirit world.
This large owl lacks ear tufts and is mottled and vermiculated in reddish brown and white. The face disc is marked with fine concentric black and white barring. The sexes are alike. The chin is white. The eyelid is orange and the iris is dark brown. The tail is barred narrowly in brown and black. The concentric barring on the face and mottled crown separate it from the brown wood owl in southern India.
There are three subspecies recognized and there are no sharp demarcations in their distributions.
The species is found in the plains in gardens and lightly wooded habitats. They roost in trees during the day choosing a branch with dense foliage. An old specimen from Lahore is noted but no records in recent times from Pakistan. The distribution extends east to West Bengal.
These owls roost during the day, usually in pairs. When disturbed they may fly in bright sunshine although they choose to shelter within a dense grove of trees. They produce an eerie chuhua-aa call with a quaver in the second note. This call is an antiphonal duet of the male and female. The male calls one or two times followed by the female's shorter and less tremulous version. The calling is more frequent in November when they begin to breed. Most Nests are found from February to April. They also produce a single note hoot and a screech not unlike that of the barn owl. The nest is a tree hollow in which two to three white eggs are laid. They feed on palm squirrels, mice and other small mammals.
