For many years, scientists have been intrigued by how pigeons can accurately find their way home from thousands of kilometers away. Now, researchers have discovered an unexpected mechanism behind this unique ability.
A new study conducted by scientists at the University of Bonn and the Max Planck Institute of Animal Behavior in Germany suggests that the secret to pigeon navigation may be linked to their liver. The research was published in the prestigious journal Science.
During the study, experts identified special immune cells in the pigeons' liver with strong magnetic properties. Because these cells accumulate iron, they may be able to sense the Earth's magnetic field.
The experiments conducted by the scientists yielded interesting results. Pigeons with temporarily reduced levels of these liver cells struggled to find their way in cloudy weather. However, they continued to fly almost without issues on sunny days.
Experts believe that pigeons use multiple methods simultaneously to navigate. In addition to sunlight and external landmarks, the Earth's magnetic field is also important. In this process, the special cells in the liver may play a key role.
The authors of the study emphasize that this discovery reveals a previously unknown mechanism of magnetic sensitivity in animals.
Interestingly, pigeons have served as reliable 'messengers' throughout human history. Ancient states, military forces, and even major news agencies used them to deliver important messages quickly.
The new discovery has shed further light on the natural mechanisms hidden behind this amazing ability of pigeons.
