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.
