Pallas's Fish Eagle

Pallas's fish eagle is a large brownish sea eagle, 72 to 85cm long with a wingspan of 180 to 215cm. It has a light sandy-brown hood and whitish face, darker brown wings and a rufous back, and a black tail with a wide white stripe. Juveniles are darker and cooler brown with no tail band, taking until about the fourth year to reach adult plumage. Females weigh 2.1 to 3.7kg and are slightly larger than males (Wikipedia, general species account).

It is partially migratory, with Central Asian birds wintering among southern Asian birds in northern India. Its diet is primarily large freshwater fish, but it is broadly opportunistic, regularly preying on water birds, and recorded prey includes pheasant-tailed jacana, lesser whistling duck and little grebe, as well as mammals, frogs, reptiles, snakes and carrion. The account opened lists Nepal among countries where it breeds.
