Eagles (and most large birds) fly by soaring; it's much more energy efficient than flapping their wings. We do use the technique for our own flights. The reason eagles and other soaring birds do this rather than flap is that they generally hunt from the air and so spend a lot of time waiting for prey. They don't need to go anywhere specific and don't need to move fast until they spot prey. Until then they want to use as little energy as possible.
A: Depending on the prey type, eagles typically capture prey with their talons and then clip the spinal chord with their bill. A: As a general rule of thumb, most raptors cannot fly very far with a load more than 30% of their own body weight. For eagles here in the Chesapeake Bay that would be 3-4 pounds. In terms of just lift, they can lift off the ground about half of their body weight.
