Bird navigation magnetic field
WebThe avian magnetic compass has been shown to function within a narrow window around the natural intensity range of the Earth's magnetic field. Birds tested in artificial magnetic fields with intensities much weaker or much stronger than the Earth's magnetic field became disoriented (Wiltschko 1968, Wiltschko et al. 2006). WebOct 13, 2024 · The same test was done on other birds, in chickens and pigeons, where the introduction of the magnetic field showed little change. The authors of the study stated: “ we show that the photochemistry of cryptochrome 4 from the night-migratory European robin is magnetically sensitive, and more so than CRY4 from two non-migratory bird species ...
