Pigeons Have Tiny Magnetic Compasses Hidden in Their Liver!

Scientists just discovered that pigeons have special iron-filled cells in their liver that work like tiny compasses, helping them sense Earth's magnetic field [the invisible force around our planet] and find their way home! When researchers removed these magic cells, the pigeons got lost on cloudy days because they couldn't use the magnetic field to navigate anymore. It turns out your pet pigeon's superpower has been hiding inside its body the whole time!
