Mystery of Lost Homing Pigeons Finally Solved

Prior research had shown that birds hear incredibly low-frequency sound waves of about 0.1 Hertz, or a tenth of a cycle per second. These infrasound waves may emanate from in the ocean and create tiny disturbances in the atmosphere. Hagstrum began to think the birds used infrasound for navigation.

on the odd day when the birds reached home from Jersey Hill without problems, the infrasound traveled between the two locations. At the other locations where pigeons headed off in the wrong direction, he showed that wind currents channeled the infrasound waves in that direction.

The explanation may solve other mysteries about pigeons — for instance, why they circle around before heading off in one direction. Because the sound waves are so long, but the birds’ ear canals are tiny, they need to circle to reconstruct the wave and figure out which way they are oriented, he said.

More interesting scientific inquiry. It is very interesting to learn what scientists are learning about our world – even when the conclusions are still preliminary and may be adjusted or refuted.

    It’s amazing that such a slow vibration can even be considered a sound, let alone heard.

    I did not have any idea about the hearing ability of pigeons, but I always wondered about the circling thing of pigeons. Now I understood the reason behind their circling, and it is amazing how they can hear such low frequency sounds.
