Pigeons navigate using magnetic sensors in livers — study

A research team in Germany has published new data on how pigeons use magnetic fields as a navigation method when visibility is limited. A key part of the long-sought answer could lie in an unexpected organ, their livers.

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.
