Best navigator using sound – The pigeon
15 mei 2012
Like elephants, pigeons can hear sounds at exceptionally low frequencies and this helps to explain their exceptional sense of direction. For example, steep hillsides reflect airbourne sound waves horizontally, providing a unique low-frequency beacon that pigeons can perceive for hundreds of miles. And there is vast source of such infra-sound in nature – thunderstorms, seismic activity, even the motion of the sea – allowing pigeons to build an acoustic landscape which is totally unknown to us. Pigeons also possess the equivalent of an in-built compass which allows them to navigate using the Earth’s magnetic field and the position of the Sun. In combination with their hearing – this makes them, probably, the best navigators in nature.
