How do migrating animals navigate vast distances with pinpoint accuracy? From birds to beetles to whales, many species rely on a mix of natural navigation systems to travel thousands of kilometers. Some detect the Earth’s magnetic field with special organs, while others use stars like Polaris to guide nighttime journeys. Landmarks such as rivers and coastlines also play a crucial role. Even smell can contribute. Salmon for instance follow the faintest of scent trails back to their birthplace. We look at what science has discovered about animal migration and navigation.
