- Title
Magnets Disrupt The Orientation Of Juvenile Ring-Billed Gulls.
- Authors
Southern, William E.
- Abstract
The article discusses a study on the hypothesis that migratory bird, Ring-billed Gulls, are using the magnetic field of the earth to inform them of their direction. The researchers study birds with less experience in migration by examining the responses of 2 to 20 day old chicks and fledglings. Biologically significant directional component in orientation cages is determined. Results show that Ring billed Gulls have the preference for bearings that are suitable for fall migration and that magnetic cues from the earth's field provide the direction for the flight.
