Geomagnetic intensity along migratory paths of white-fronted geese

Using measurements from ESA’s Swarm mission, scientists have developed a new tool that links the strength and direction of the magnetic field to the flight paths of migrating birds, such as greater white-fronted geese. This is a huge step forward to understanding how animals use Earth’s magnetic field to navigate vast distances. The image shows the values of geomagnetic intensity that the geese encountered on their journeys. These maps show real values that the geese encountered on their migration from Siberia to Germany.
