Abstract

Currently at least two independent systems of magnetoreception are believed to exist in birds, based on different biophysical principles, located in different parts of their bodies, and having different innervation. One magnetoreceptory system is located in the retina and may be based on photo-induced biradical chemical reactions on the basis of cryptochrome. Information from these receptors is processed in a specialized part of visual Wulst, the so-called Cluster N. There are good reasons to believe that this visual magnetoreceptor processes compass magnetic information which is necessary for migratory orientation. The second magnetoreceptory system is probably iron-based (biogenic magnetite), is located somewhere in the upper beak (its exact location and ultrastructure of receptors remain unknown), and is innervated by the ophthalmic branch of trigeminal nerve. It cannot be ruled out that this system participates in spatial representation and helps forming either a kind of map or more primitive signposts, b
