Within Europe, after leaving breeding ponds in the summer or autumn, amphibians will often travel considerable distances away from breeding ponds, which may take many months. For example the common toad may migrate between 50 m and 5 km from breeding sites. Research has shown that amphibians probably use a range of methods to navigate which may include: visual, olfactory, auditory, celestial, lunar and magnetic cues. However, not all species can use all techniques. For example, some species are able to use magnetic cues, while others are not.
