Pallas Fish Eagle

  
The Life of Animals | Pallas Fish Eagle | It has a light brown tint with a white face. The wings are dark brown back and brown, darker below. The tail is black with a broad white fat. Juveniles are darker overall, with no band on the tail. Women at 2.1-3.7 kg (4.6 to 8.2 lbs), are slightly larger than the males, from 2 to 3.3 kg (4.4 to 7.3 lbs). Since all species is slightly heavier than the eagle, is one of the greatest performance ever measured weightlifting for a flying bird.


This species is most difficult to place the eagle. The cytochrome b mitochondrial DNA sequence data is not able to suggest a reliable phylogenetic space for the bottom of the sea-eagles. However, some data are derived from molecular data, and especially the morphology and biogeography: This species retains the ancestral eye dark, bill and claws of the first sea eagles, shared with the ancient tropical origin. It


Distribution indicates that this species has evolved quite independently of other lines of sea eagle, but molecular data suggest that caution is perhaps closest to the Holarctic species. Apparently, this species reached the current, mainly landlocked particular distribution among sea eagles as a result of the collision of the Indian plate with Eurasia.


Conservation of Pallas's eagle is vulnerable, with a population of about 2,500 to 10,000 remain. In India, the eagle as threatened by the spread of water hyacinth (Eichhornia spp.), Who spread through the lakes and find prey difficult.
