Homing pigeon's liver shows advanced navigation
A recent study has revealed that homing pigeons rely on iron-rich immune cells in their liver to sense the Earth's magnetic field, aiding them in navigation during flight. The results showed that these cells contribute to a navigation sensing system that uses signals from the magnetic field and the sun to achieve precision in covering hundreds of kilometers without losing their way. The study confirms that pigeons depend on multiple navigation mechanisms, which interact depending on weather conditions and distances.
