In fact, migratory birds are suspected to use magnetism, rather than sight, to make their long journeys. Bats and dolphins - even if they employ ultrasounds to find food, echolocation having been proved as not effective over large distances - were found to use Earth's electromagnetism in their long migrations.

There is no chemically sensible reason why bacteria would have favored this compound of iron over all others unless the magnetic properties of this element were important, or useful, in some way. Biologists think that bacteria may use these internal compasses to sense where 'down' is so that they can find food.

If they used magnetic polarity in roosting, the scientists suggest, the bats are also likely use polarity to navigate, such as when Nyctalus noctula migrate up to 1600 km ... The scientists explain that animals which use magnetism to navigate are generally thought to use light exposure, magnetite receptors, or both.

WASHINGTON: Researchers at the Universities of Leeds and Princeton have found that animals have a magnetic mineral called magnetite in their bodies, which acts as an internal compass to help them find directions.

In animals, the use of small magnetic particles (e.g., magnetite) as magnetoreceptors has been suggested. The use of magnetite has been shown in magnetotactic bacteria that are rotated by a magnetic field because of the torque exerted on their magnetite particles.
