The mountain hawk-eagle (Nisaetus nipalensis) or Hodgson's hawk-eagle, is a large bird of prey native to Asia. The latter name is in reference to the naturalist, Brian Houghton Hodgson, who described the species after collecting one himself in the Himalayas. A less widely recognized common English name is the feather-toed eagle. Like all eagles, it is in the family Accipitridae. Its feathered tarsus marks this species as a member of the subfamily Aquilinae. It is a confirmed breeding species in the northern part of the Indian subcontinent, from India, Nepal (hence the epithet nipalensis) through Bangladesh to Thailand, Taiwan, Vietnam and Japan, although its distribution could be wider still as breeding species. Like other Asian hawk-eagles, this species was earlier treated under the genera of Spizaetus but genetic studies have shown this group to be paraphyletic, resulting in the Old World members being placed in Nisaetus (Hodgson, 1836) and separated from the New World species. As is typical of hawk-eagles, the mountain hawk-eagle is a forest dwelling opportunistic predator who readily varies its prey selection between birds, mammals and reptiles along with other vertebrates. Although classified currently as a least-concern species due its persistence over a rather wide distribution, this species is often quite rare and scarce and seems to be decreasing, especially in response to large-scale habitat degradation and deforestation.

With luck
About 10% of wildlife watchers report a Mountain Hawk-Eagle sighting in Khao Yai National Park on a given day, based on 193 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 135th most-seen of the 278 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.
November
In that month about 20% of wildlife watchers report a Mountain Hawk-Eagle in Khao Yai National Park on a given day, against under 5% in May and August–September, the lowest months. That is one of Khao Yai National Park's driest months, with about 60 mm of rain against 330 mm in September.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mountain Hawk-Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 11
Of the 11 parks where we can rate Mountain Hawk-Eagle sightings, Khao Yai National Park ranks 4th at about 10%. The best odds are in Royal Manas National Park (Bhutan, about 20%), Taroko National Park (Taiwan, about 10%) and Langtang National Park (Nepal, about 10%).
Same family: Accipitridae
The closest relatives of the Mountain Hawk-Eagle that you can see in Khao Yai National Park (family Accipitridae, Hawks, Eagles, and Kites) are Crested Serpent Eagle (about 20%), Oriental Honey-buzzard (about 20%) and Black Eagle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mountain Hawk-Eagle is recorded against all the birds logged in Khao Yai National Park (193 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.
