Homing Pigeons May Use Low Frequency Sound Maps To Locate Home
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 â 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.
