Bird ringing (UK) or bird banding (US) is the attachment of a small, individually numbered metal or plastic tag to the leg or wing of a wild bird to enable individual identification. This helps in keeping track of the movements of the bird and its life history.
In the fall of 1803, American Naturalist John James Audubon wondered whether migrating birds returned to the same place each year. So he tied a string around the leg of a bird before it flew south. The following spring, Audubon saw the bird had indeed come back. Scientists today still attach tags, such as metal bands, to track movement of animals.
The program is responsible for many aspects of bird banding in the United States and Canada: it grants permits to bird banders, fills orders for bands of various sizes, collects data from banding stations, receives reports from people who have found birds carrying bands, and makes its database available to appropriate parties.

The new leg design enabled the robot to perform a range of movements like walking, hopping over a gap, and jumping onto an obstacle. Raven’s jumping legs also allowed it to start flight at a ...
Birds are usually caught in mist nets to be measured and banded. [6] Additionally, bird banding provides critical information about the migration patterns of birds. When a banded bird is encountered in a location far from where it was initially banded, it indicates long-distance movements and migration routes.
Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet).
