Why Do Cows Align North-South When Grazing?

💡 The Answer

• Cows and deer tend to orient their bodies along the Earth's magnetic field lines when grazing or resting.
• This magnetic alignment was observed using satellite imagery of herds across continents.
• The exact reason is unknown, but it may help with navigation or thermoregulation.
• Not all animals exhibit this; it is most noticeable in open fields with low wind.
