Eagles demonstrate their ability to navigate and orient themselves during long-distance migrations across continents by using a combination of visual landmarks, the sun's position, Earth's magnetic field, and possibly even their sense of smell. They are known to have keen eyesight and can use prominent landmarks such as mountain ranges, rivers, and coastlines to guide their way. Additionally, they are believed to be able to sense the Earth's magnetic field and use it as a compass for navigation. Some studies also suggest that eagles may use their sense of smell to help them find their way during migrations.
