Bird banding is a scientific method used to study and monitor bird populations. Researchers place lightweight, numbered bands around a bird's leg to identify individual birds. This helps track their movements, breeding patterns, and survival rates over time. The process is typically done by trained professionals or volunteers who capture birds using nets. After banding, the birds are carefully released back into their habitat. This practice contributes valuable data to ornithology, the study of birds, and helps in conservation efforts by providing insights into the health of ecosystems.
