banding

The term "banding" in zoology, specifically ornithology, refers to the practice of attaching numbered leg bands to birds for identification and study. This technique, used since the early 19th century, helps researchers gather information on bird longevity and migration patterns. Hundreds of thousands of birds are marked annually with these bands, contributing valuable data to the scientific understanding of avian life. While "banding" in zoology is about marking birds, the term "branding" in agriculture and other contexts involves permanently marking livestock or goods for identification of ownership, quality, or other purposes, often using hot or cold irons, tattoos, or paint. A leg band is an identification tag placed on a bird's leg.123
