Microbats make use of magnetoreception, in that they have a high sensitivity to the Earth's magnetic field, as birds do. Microbats use a polarity-based compass, meaning that they differentiate north from south, unlike birds, which use the strength of the magnetic field to differentiate latitudes, which may be used in long-distance travel. The mechanism is unknown but may involve magnetite particles.
Magnetoreception
In similar fashion, European ("Bufo bufo") and Natterjack ("Epidalea calamita)" toads appear to rely, at least somewhat, on magnetic information for certain orienting behaviours. These species of anurans are known to rely on vision and olfaction when locating and migrating to breeding sites, but it seems magnetic fields may also play a role. When randomly displaced from their breeding sites, these toads remain well-oriented, and are capable of navigating their way back, even when displaced by more than 150 meters. However, when this displacement is accompanied by the experimental attachment of small magnetic bars, toads fail to relocate breeding sites. Considering experimental attachment of non-magnetized bars of equal size and weight does not affect relocation, it seems that magnetism is responsible for the observed disorientation of these toads. Therefore, researchers have concluded that orientation toward breeding sites in these anurans is influenced by magnetic field information.
