The brown fish owl (Ketupa zeylonensis) is a fish owl species in the family known as typical owls, Strigidae. It is native from Turkey to South and Southeast Asia. Due its wide distribution it is listed as Least Concern on the IUCN Red List. It inhabits forests and wooded wetlands. Of the four living species of fish owl, it is the most widely distributed, most common and best-studied. It occupies a range of over 7,000 km. The brown fish owl has prominent ear tufts and rufous brown upperparts that are heavily streaked with black or dark brown. Its underparts are buffy-fulvous to whitish, with wavy dark brown streaks and finer brown barring. Its throat is white and conspicuously puffed. Its facial disk is indistinct, the bill dark and the iris golden yellow. Its featherless feet are yellow. Two-year old brown fish owls are somewhat paler than adults. Female and male differ slightly in size. In body size, it ranges from 48 to 61 cm with a wingspan from 125 to 140 cm. Its weight varies considerably, ranging from 1.1 to 2.5 kg. Some of the variability is attributed to the range of sizes across the subspecies. Also, females are invariably at least somewhat larger than males and condition of birds is variable. It is slightly larger than the buffy fish owl with a darker brown hue.
