The dusky eagle-owl (Ketupa coromanda) is an owl species in the family Strigidae that is widespread in South and Southeast Asia. The type specimen used to describe the species was collected on the Coromandel Coast, which was used for the specific epithet. It is listed as Least Concern on the IUCN Red List. The species's extent of occurrence is estimated at 9,250,000 km2 (3,570,000 sq mi). However, volunteer generated databases such as eBird.org suggest that the available extent of occurrence is a vast over-estimate.
The species was first described by John Latham in 1790 as Strix coromanda. This is the nominate subspecies that occurs in South Asia. In the 20th century, the following subspecies was described: Ketupa coromanda klossii described by Herbert C. Robinson in 1911 was an adult dark brown male eagle-owl collected in north Perak, Malaysia. Only four skins are known. This subspecies is thought to occur in Southeast Asia.
The dusky eagle-owl is a large greyish-brown owl with prominent ear tufts. Its underparts are greyish white with some dark brown streaks, and its dark brown wings have some whitish streaks. K. c. klossii is similar to the nominate... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dusky Eagle-Owl sighting in Royal Bardia National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 188th most-seen of the 233 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April, July and December
In those months about 10% of wildlife watchers report a Dusky Eagle-Owl in Royal Bardia National Park on a given day, against under 5% in January–March, May–June and September–November, the lowest months. August has too few records to rate.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Dusky Eagle-Owl sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Dusky Eagle-Owl sightings, Royal Bardia National Park ranks 4th at under 5%. The best odds are in Keoladeo National Park (India, about 40%), Kaziranga National Park (India, about 10%) and Ranthambore National Park (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky Eagle-Owl is recorded against all the birds logged in Royal Bardia National Park (12 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.
