Bird migration how you can help save birds

It is the time of year when birds migrate. One of the dangers to migratory birds are ground lights, even porch and street lights. Many birds are killed because of ground lights. We can help by turning off all outside lights when they are not needed. Here are two articles for you to read. The one is a newsletter that comes out very two weeks by Brome, a maker of the very best squirrel proof bird feeders. I know because I have tried them all. The Brome newsletter is free and anyone can subscribe to it. The newsletter is a great learning tool for adults and children. They also have a photo contest each month.

New discovery about how birds migrate

Many birds migrate thousands of miles each spring and fall. Often these birds return to the same area and even the same bird houses or nesting sites. When you consider that being off even a half of a degree could cause birds to be hundreds of miles away from their destination, it is an amazing feat of navigation.

Researchers have long believed that birds follow the magnetic field of the Earth to navigate but were not sure how they accomplished this with such accuracy. Recently Researchers at Lund University in Sweden believe they have discovered the secret. It is a unique protein found in bird’s eyes.

Atticus Pinzón-Rodríguez, one of the researchers involved in the study explained that the cryptochromes protein, Cry4, is the only one that remains constant both day and night. According to the study all birds have this protein which is sensitive to the magnetic fields of the Earth. They found that even birds that do not migrate have the Cry4 protein.

The researchers feel that more studies are needed to fully understand how Cry4 works, but that it is a step in the right direction. Eventually they feel it may help develop new navigation systems for people.
