I wanted to pass on a very interesting article from the Chicago Tribune about bird migration. Apparently there are several studies now that show that birds have a sense of the earth’s magnetic fields, that they can see these subtle differences, and use the information to guide their migrations!
Take a look at this article by Jeremy Manier of the Chicago Tribune titled “Science closes in on how birds manage to fly south”. I found it very interesting and informative. Click on this link: Magnetic Migration
Enjoy.
