How do migratory birds navigate during their long journeys?

Migratory birds use a combination of environmental cues to navigate during their long journeys. They rely on the position of the Sun and stars for direction, as well as Earth’s magnetic field for orientation. Some species also use landmarks such as coastlines or mountain ranges to guide their path. Additionally, birds are able to detect changes in atmospheric pressure, which helps them determine the best time to migrate. This complex navigation system allows birds to travel thousands of kilometres with remarkable precision.
