Bird banding is done to learn more about birds. Careful records are kept by the licensed bird banders of each bird they band.  Copies of these records are turned over to the Bird Banding Laboratory.  By reporting on banded birds you find, you can help contribute important information on these birds, such as how long they live, where they disperse to, and where they were banded.  Your report will be sent to the bird bander.  Often, if you request information on the bird you reported, you can learn where and when it was banded.
