Their call is a (hoo) hoo hoo HOO, or a deep goke-goke-ga-LOOO, or a loud scream. Their alarm call is a bark, wow-wow. Some subspecies are known to produce distinct vocalizations; they are also different in appearance and parapatric, and might be distinct species: The northern Strix (leptogrammica) newarensis group (Himalayan wood-owl; present subspecies newarensis, ticehursti, laotiana and caligata) which occur from the Himalayan foothills of Kashmir east to Taiwan have a soft low to-hooh not unlike a rock dove cooing. S. (l.) bartelsi (Bartels's wood-owl), Javan wood-owl from Java, the southeasternmost taxon, has a loud, forceful, single HOOH! with long pauses between calls.

This species is highly nocturnal and is commonly found in dense forests. It can often be located by the small birds that mob it while it is roosting in a tree. The diet of the brown wood owl consists mainly of small mammals, birds, and reptiles.
