A new study says homing pigeon livers act like compasses. Other experts aren’t so sure

A Science study (Max Planck) finds iron macrophages in pigeon livers may act as compasses; depleting them disoriented birds on cloudy days. Multiple experts dispute it: the iron barely responds to Earth's weak field and no brain signal pathway is demonstrated.

Pigeons navigate using magnetic sensors in livers — study

University of Bonn and Max Planck researchers found that iron-rich macrophages in pigeon livers act as the primary magnetic navigation sensor — pigeons deprived of these cells lost orientation under overcast skies. The organ-level mechanism offers new models for bio-inspired sensor design and GPS-independent navigation research.
