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 (4,300 mi).
The brown fish owl was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other owls in the genus Strix and coined the binomial name Strix zeylonensis. Gmelin based his description on the "Great Ceylonese horned owl" that had been described and illustrated by the naturalist Peter Brown in his book New Illustrations of Zoology. Joan Gideon Loten, an administrator in the Dutch East India Company had provided Brown with a picture of the owl that had been drawn by the Ceylonese artist Pieter Cornelis de Bevere. The brown fish owl is now placed in the genus Ketupa that was introduced in 1830 by the French naturalist René Lesson... Wikipedia →

With luck
About 10% of wildlife watchers report a Brown Fish-Owl sighting in Kanha National Park on a given day, based on 530 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 113th most-seen of the 286 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Brown Fish-Owl in Kanha National Park on a given day, against under 5% in July to December, the lowest months. That is one of Kanha National Park's driest months, with about 30 mm of rain against 430 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Brown Fish-Owl sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
11th of 19
Of the 19 parks where we can rate Brown Fish-Owl sightings, Kanha National Park ranks 11th at about 10%. The best odds are in Wilpattu National Park (Sri Lanka, about 30%), Ranthambore National Park (India, about 20%) and Bandhavgarh National Park (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Brown Fish-Owl is recorded against all the birds logged in Kanha National Park (530 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
