Unlike the owls in the Harry Potter books, homing pigeons can’t be given an address to fly to. But if they are taken away from home, even as far as 1100 miles away, homing pigeons can always find their way back.
This ability has made homing pigeons good messengers for thousands of years. Homing pigeons were widely used in both World War I and World War II. Several birds even received medals for delivering important messages during wartime.
But how do homing pigeons find their way home overlong distances? Scientists believe that homing pigeons have both a compass mechanism and a map mechanism in their bodies.
A homing pigeon’s compass mechanism relies upon the Sun. Like many other birds, homing pigeons can use the position and angle of the Sun to determine the proper direction for flight.
Homing pigeons’ map mechanism relied on low-frequency infrasound. Humans cannot hear these sounds. But these sounds are created by nearly everything. Homing pigeons listen to these sounds until they recognize the sounds of their home.
