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.
An eagle in flight can reputedly sight a rabbit two miles away. Talonâeye coordination is a hunting imperative. From its perch at the top of trees, the eagle can dive at speeds of 125â200 miles per hour (201â322 km/h) to catch its prey by its talons.he eyeball is so large and so tightly fit that the eagle can barely turn it within the socket. That the eyes are located in front of its head with face forward and looking slightly askew is an advantage. Though its hearing does not match its eye power, mating calls are said to be heard for several miles.
