Animals navigate through migration routes using a variety of methods, including geomagnetic cues, celestial cues (such as the position of the sun or stars), landmarks, and even the Earth's magnetic field. These cues help animals maintain a sense of direction and navigate vast distances during their migrations. Additionally, some species rely on visual landmarks, olfactory cues, and even environmental factors like wind patterns to guide their migration routes. Overall, animals have evolved sophisticated navigation strategies over time to ensure successful migrations.
