📝 Description
New scientific research highlights a sophisticated navigation system utilized by migratory birds, often compared to a built-in GPS. Scientists have pinpointed a specific brain region, known as Cluster N, which activates when birds rely on Earth’s magnetic field for directional guidance. This mechanism functions selectively, acting as a biological compass during long-distance travel.
Birds complement this magnetic sensing with navigational inputs from celestial cues, such as the Sun and stars. The ability to sense magnetic fields is attributed to magnetically sensitive proteins located in the birds' eyes. This breakthrough offers insight into the precision of avian migration across thousands of kilometers and raises questions regarding potential threats posed by human activity to these natural navigation capabilities.
