ı am goıng to talk about the eagles which ıs the most predacious bird in the world.First of all it differ from others for its good visual ability.They are large birds of pray which are members of the bird family Accipidridae and belong to several genera which are not necessarily closely related to each other.Most of the more than 60 species occur in Eurasıa and Africa.Like all birds of prey, eagles have very large powerful hooked beaks for tearing flesh from their prey, strong muscular legs, and powerful talons claws.Eagles are differentiated from other birds of prey mainly by their larger size, more powerful build, and heavier head and bill.they also have extremely keen eyesight which enables them to spot potential prey from a very long distance.This keen eyesight is primarily contributed by their extremely large pupils which cause minimal diffraction (scattering)of the incoming light. There are many types of eagles some of them bald eagles and whıte winged eagles.
