Do Birds Use Stars to Navigate at Night During Migration
âdo birds that migrate at night use the stars to navigateâ
Summary
Nocturnal migratory birds rely on stellar cues to orient and maintain their migratory routes. Experiments using planetariums and field observations have demonstrated that birds can read the pattern of stars and adjust their internal compass accordingly, often calibrating with the sun or magnetic field when visible. This starâbased navigation is a wellâestablished component of their longâdistance migration.

Indeed birds âdisplacedâ artificially along the eastâwest axis using a planetarium [18] do not react to a mismatch between the positions of the stars and the time at their true location. Most species of pinniped are not migratory, but many conduct long foraging and dispersal journeys ...

Just like the traditional seafaring navigators of Polynesia, birds can also read the stars to orient themselves on migration. Ornithologist Stephen Emlen discovered that young birds look up at the stars from their nests at night.

In addition, migratory birds regularly recalibrate their night compass by reference to the magnetic compass in order to take account of changes in the configuration of constellations as the migratory bird moves south in autumn and north in spring. A further complication for star-based night navigation is that trans-Saharan migrants, whose destination is far away in South Africa, are confronted with completely different star configurations as they cross the equator and change hemispheres (Figure 9).
