Very Important: to those who lost a bird & to those who found a bird
Remember to not post leg band numbers publicly as this information should remain private and confidential. Band numbers are used for identification purposes only so that owners of missing birds can match up their bird's band number with the band numbers of those birds that have been found.

If you are a finder and have found bird and an owner of a missing bird provides you with the matching leg band number then it is safe to say this person is the legitimate and rightful owner of the bird you found.
