Bird ringing or bird banding is a technique used in the study of wild birds, by attaching a small, individually numbered, metal or plastic tag to their legs or wings, so that various aspects of the bird's life can be studied by the measurements taken during the capture, such as molt, fat content, age, sex, wing and tail. An added bonus is the occasional ability to re-find a the same individual later. This recapture or recovery of the bird can provide information that includes migration, longevity, mortality, population studies, territoriality, feeding behaviour, and other aspects that are studied by ornithologists.
