About 50 years ago the first evidence that birds use odours in navigation was found. Afterward evidence has mounted for this olfactory navigation hypothesis. The precise way birds utilize olfactory information for navigation and orientation is not fully known but several ideas have been postulated and tested. Most evidence has been found through experiments with homingpigeons,Columba liviadomestica,but convincing evidence has also been found in procellarriformes and some migratory birds. These three sampled species/orders navigate through vastly different circumstances and as such need different navigational information which odours could provide. Because odours consist of easily dispersed gassesolfactoctory navigation is not without limits. It is, however, complemented and supported by other navigational mechanisms like landmarks. When taken together these mechanisms form a steady and reliable navigational system that is versatile enough to potentially serve different species with different needs.
