New Study Reveals How Pigeons Navigate Using Their Gut Instincts

Recent research has uncovered that pigeons possess a unique internal compass located in their liver, which helps them navigate, especially in cloudy conditions. This discovery, published in the journal Science, reveals that iron-rich immune cells in pigeons can sense Earth’s magnetic field, allowing them to find their way when other cues, like sunlight, are unavailable. During experiments, pigeons with these cells successfully completed navigation tasks, while those without became lost in overcast weather. This finding could change our understanding of animal navigation and the role of the immune system. The researchers plan to further investigate how these cells communicate with the nervous system.

Key Details: • Pigeons rely on iron-rich liver cells to navigate using Earth's magnetic field. • The study was published in the journal Science and highlights a new function of the immune system. • Experiments showed that pigeons without these cells got lost in cloudy conditions. • Future research will explore how immune cells communicate with the brain for navigation.
