The barred eagle-owl (Ketupa sumatrana), also called the Malay eagle-owl, is a species of eagle owl in the family Strigidae. It is a member of the large genus Ketupa, which is found on most of the world's continents. This relatively little-known species is found from the southern Malay Peninsula down a string of several of the larger southeast Asian islands to as far as Borneo. It forms a superspecies with the physically similar but larger spot-bellied eagle-owl (Ketupa nipalensis), although the two species appear to be allopatric in distribution.
It is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests. It typically is a resident of evergreen forests with pools or streams, but also ranges into large gardens with tall, densely foliated trees, such as the Bogor Botanical Gardens found in West Java as well as wooded groves in cultivated country, both sometimes not far from human habitations. It usually ranges in elevation from sea-level to roughly 1,000 m (3,300 ft) but can range up to about 1,600 m (5,200 ft) or more at locations like Mount Gede in West Java and Mount... Wikipedia →

Rare
Under 5% of wildlife watchers report a Barred Eagle-Owl sighting in Sepilok on a given day, based on 133 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st most-seen of the 242 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, May, September and November–January
In those months about 10% of wildlife watchers report a Barred Eagle-Owl in Sepilok on a given day, against under 5% in February, April, June–August and October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Barred Eagle-Owl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 7 parks where we can rate Barred Eagle-Owl sightings, Sepilok ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Way Kambas National Park (Indonesia, under 5%).
GBIF citizen-science records
It is estimated from how often the Barred Eagle-Owl is recorded against all the birds logged in Sepilok (133 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.
