If you click the link below you will see a heart warming story of how in America at the Jefferson National Expansion Memorial at St. Louis, MO it’s been decided to turn the lights off to help night flying migrating birds.
It seems that city lights and any artificial light can upset a migrating bird and send it off course. How tragic is that?
Some migrating birds navigate by the stars. They will be safer now the artificial lights cannot send them off course. They will be able to see the stars and will keep flying on course
So artificial light is another item I can add to the reasons why migratory birds are declining in some places.
It seems though that climate change could cause the biggest problem for migrating birds.
