Loggerhead sea turtles (Caretta caretta) can learn to associate food with the geomagnetic signatures of various oceanic regions, suggesting that they are able to find known foraging areas using an ...
Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favourite spots, scientists said on Wednesday. Some animals that migrate ...
For decades, scientists have known that migratory birds use Earth’s geomagnetic field—along with light, stars, and other cues—to guide them on remarkably long journeys. But it is unclear just how ...
The monarch butterfly uses a magnetic compass to guide its extraordinary migration thousands of km across North America, scientists say. Monarchs are known to possess a Sun compass but even on cloudy ...
