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.

Rare
Under 5% of wildlife watchers report a Mountain Hawk-Eagle sighting in Kathmandu on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 276th most-seen of the 312 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mountain Hawk-Eagle in Kathmandu on a given day, so our monthly data shows no clear season.
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.
Only Kathmandu, in our data
Kathmandu is the only city on Wallace's Line with enough records to rate Mountain Hawk-Eagle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Accipitridae
The closest relatives of the Mountain Hawk-Eagle that you can see in Kathmandu (family Accipitridae, Hawks, Eagles, and Kites) are Black Kite (about 90%), Steppe Eagle (about 10%) and Booted 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 Kathmandu (12 verified sightings), 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.
