A binding band for bird ring and a bird ring structure are provided whose construction is simple and inexpensive, whose fitting to the bird ring is easy, but detachment is not easy, and that enable not only reliable and easy recognition of individual birds, but also error-free reception, storage, and transmission of information about a race or records thereof, thereby reliably preventing undue use.The binding band for bird ring 1 comprises a body part 2, an insertion end 3 provided at one end of the body part 2, an engagement attaching part 4 that is provided at another end of the body part 2 and has a hollow insertion passage part 25 into which the insertion end 3 is irreversibly inserted and maintained, and an information processing part 7 that is a portion of the body part 2, provided between a central part C of the body part 2 and the insertion end 3, and can store predetermined information and transmit/receive the information.
