Severe Space Weather Events Disrupt Nocturnal Bird Migrations, Researchers Find

Space weather from the Sun, such as coronal mass ejections, disturbs Earth’s magnetic field, causing the aurorae and potentially decreasing the magnetic field’s reliability for migrating birds. Image credit: John Megahan.

Earth’s magnetic field is occasionally but regularly impacted by bursts of energy from the Sun (space weather), such as coronal mass ejections. Birds and other animals depend on the geomagnetic field for long-distance navigation during their seasonal migrations. In new research, scientists from the University of Michigan and elsewhere used long-term datasets to test whether geomagnetic disturbance is correlated with the number of birds migrating,...
