How do eagle catch a fish?

The eagle's eyesight is especially remarkable. With vision about five times sharper than our own, an eagle can spot a target as small as a rabbit up to a mile away.   The claws on an eagle's toes are curved and razor-sharp for catching and holding their prey.  Rough bumps on the eagle's toes also help them hold slippery, wiggling fish. A eagle’s feet are important for capturing food and also as a method of protection.  To catch fish, eagles generally watch the water surface from a perch or while soaring in the air. Then they swoop down close to the water and drop their feet right in the water to catch the fish.   Unlike other birds, which eat seeds or insects and travel only short distances in search of a meal, the eagle must often fly great distances in order to find worthy fare.  Riding upon vertically spiraling columns of warm air called thermals, the eagle can travel up to twenty miles per hour virtually without effort. The eagle is further aided in flight because its bones are hollow. Unbelievably, the total weight of an eagle skeletal system is only half the weight of its feathers! With a wingspan of seven to eight feet and a wide and rudder-like tail, the eagle was built to master the skies.
