PAKHI DEKHUN PAKHI CHINUN # 311 (Observe the Bird and recognize)..PALLAS'S FISH EAGLE...[From a Photograph of UDAYAN BORTHAKUR] ....WATERCOLOUR...5INCH*7INCH...2014....PALLAS'S FISH EAGLE (Haliaeetus leucoryphus), also known as Pallas's Sea Eagle orBand-Tailed Fish Eagle, is a large, brownish sea-eagle. It breeds in Central Asia, between the Caspian Sea and the Yellow Sea, from Kazakhstan and Mongolia to the Himalayas,Bangladesh and northern India. 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. It has a light brown hood over a white face. The wings are dark brown and the back rufous, darker underneath. The tail is black with a wide, distinctive white stripe. Underwings have a white band. Juveniles are overall darker with no band on the tail. It measures 72–84 cm (28–33 in) in length with a wingspan of 180–215 cm (71–85 in). Females, at 2.1-3.7 kg (4.6-8.2 lbs), are slightly larger than males, at 2-3.3 kg (4.4-7.3 lbs). Its diet consists primarily of large freshwater fish. They also regularly predate water birds, including adult Greylag Geese, by assaulting them on the surface of the water and then flying off with the kill. Since that goose species is slightly heavier than the eagle, this is one of the greatest weight-lifting feats ever recorded for a flying bird Besides direct persecution, humans contribute to the decline of this species through habitat degradation, pollution, and draining or overfishing lakes. In India, the eagle is also threatened by the spread of water hyacinth (Eichhornia spp.) which spread over lakes and make finding prey difficult.[INFORMATION : WIKIPEDIA]
