Magnetic orientation is critical to the migratory success of many bird species. By studying the influence of light on the ability of migratory birds to orient to magnetic signals, researchers have ...

WORCESTER, MA – Each fall millions of monarch butterflies use a sophisticated navigation system to transverse 2,000 miles from breeding sites across the eastern United States to an overwintering ...

Until recently, people believed that the ability to orientate themselves by the Earth's magnetic field was restricted to migratory birds. Now ornithologists at Frankfurt University have discovered ...

The magnetic sense in migratory birds has been studied in considerable detail: unlike a boy scout's compass, which shows the compass direction, a bird's compass recognizes the inclination of the ...

WORCESTER — Collaborative research between the University of Massachusetts Medical School and Worcester Polytechnic Institute has identified a new component of monarch butterflies' navigation system.

Migratory animals use different mechanisms to sense the Earth's magnetic field for homing and navigation. Writing in Current Biology, a team led by Wolfgang Wiltschko shows that bright coloured light ...
