Homing pigeons can find their own cozy loft from hundreds of kilometers away. A brain structure enables exploratory jaunts during the birds’ prodigious flights home, a new study suggests.
The results, published July 16 in the European Journal of Neuroscience, bring scientists a little closer to understanding how animals and people find their way in the world.
Sights, smells and Earth's magnetic field may all help a homebound pigeon navigate. Along with other brain regions important for homing behavior, the hippocampus acts as a critical navigator, pointing out familiar landmarks near a pigeon’s home.
