Pallas's fish eagle (Haliaeetus leucoryphus), also known as Pallas's sea eagle or band-tailed fish eagle, is a large, brownish sea eagle. It breeds in the east Palearctic in Kazakhstan, Russia, Tajikistan, Turkmenistan, Uzbekistan, Mongolia, China, India, Nepal, Bangladesh, Myanmar and Bhutan. It is listed as Endangered on the IUCN Red List. It is partially migratory, with Central Asian birds wintering among the southern Asian birds in northern India, and also further west to the Persian Gulf.
The Pallas's fish eagle has a light sandy-brown hood and a whitish face. The wings are darker brown and the back rufous. The long, slender wings (particularly slender for a sea eagle) are rather dark brown underneath. The tail is black with a wide, distinctive white stripe. Juveniles are overall darker, cooler brown with no band on the tail but with several pale areas on the wing, including the underwing coverts and inner primaries. This results in underwings that have a white band in young fish eagles. It takes until the 4th year or so to obtain adult plumage. Among related species, it mainly overlaps in range with the quite dissimilar much shorter winged and slightly smaller... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pallas's Fish Eagle sighting in Royal Manas National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 322nd most-seen of the 388 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Pallas's Fish Eagle in Royal Manas National Park on a given day, against under 5% in March–July and October–December, the lowest months. Those are among Royal Manas National Park's driest months, with about 45 mm of rain a month against 930 mm in July. August and September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pallas's Fish 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 5
Of the 5 parks where we can rate Pallas's Fish Eagle sightings, Royal Manas National Park ranks 4th at under 5%. The best odds are in Kaziranga National Park (India, about 60%), Jim Corbett National Park (India, about 20%) and Manas National Park (India, under 5%).
Same family: Accipitridae
The closest relatives of the Pallas's Fish Eagle that you can see in Royal Manas National Park (family Accipitridae, Hawks, Eagles, and Kites) are Crested Serpent Eagle (about 20%), Mountain Hawk-Eagle (about 20%) and Black Eagle (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pallas's Fish Eagle is recorded against all the birds logged in Royal Manas National Park (15 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.
