Eagles are remarkably adapted for movement through air, on land, and even in water.
Flight
Eagles have large, powerful wings built for soaring and gliding. Lightweight, aerodynamic feathers, strong flight muscles, and tail feathers that act like rudders allow them to steer and stay aloft with minimal effort by riding rising air currents.
Perching
Powerful talons and a large, opposable hind toe (hallux) let eagles grip branches firmly. Strong leg muscles help them balance on narrow perches.
Walking
Eagles walk upright on two legs, though their legs are relatively short compared to their wingspan. Their large talons provide traction on branches, rocks, and other surfaces.
Swimming
Some species, such as the Bald Eagle, have partially webbed toes and streamlined bodies that help them move through water. They can use their wings to propel themselves and stay afloat, especially when catching fish near the surface.
Overall, eagles are best known for graceful, powerful flight, with capable but more limited movement on land and in water.
