🐦🧭 A team at the University of #Bonn found that #pigeons rely on iron-rich #macrophages in their livers to sense #Earth’s magnetic fields.

When researchers deactivated these #cells, the #birds lost their way on overcast days – but navigated fine under sunny skies, confirming a backup magnetic system that kicks in when visual cues aren’t available.
