Provided is a racing pigeon foot ring structure. The racing pigeon foot ring structure is a flexible body (10) buckled at one end (11) or integrated with a belt body (30, 301) the body (10) is fixedly embedded with a wireless radio frequency identification label (14) at a proper position the other end (12) of the body (10) is provided with a penetration slot (121) a breakable tab (16) capable of being torn off by an external force is formed on the outer side wall of the penetration slot (121) one end of the belt body (30, 301) corresponding to the penetration slot (121) is a restraining end (32) the restraining end (32) penetrates through the penetration slot (121), passes by and covers the breakable tab (16), and encloses a closed foot ring together with the body (10) to encircle a pigeon foot. When the racing pigeon arrives at a pigeon loft, if a sensing timer is used, the wireless radio frequency identification label (14) on the body (10) of the racing pigeon foot ring structure can sense the arrival time of the racing pigeon upon landing and if a pigeon clock type timer is used, the breakable tab (16) can be torn off, the belt body (30, 301) can be flexed to reduce the foot ring outer diameter and put into the pigeon clock type timer to record the time. Therefore, the racing pigeon foot ring structure is suitable for two different kinds of timers.Linvention concerne une structure de bague pour patte de pigeon de compétition, caractérisée en ce que : la structure est constituée dun corps souple (10) replié à une extrémité (11) ou intégré avec un corps (30, 301) de courroie le corps (10) enrobe de façon fixe une étiquette (14) didentification sans fil par radiofréquence dans une position appropriée lautre extrémité (12) du corps (10) est munie dune rainure (121) de pénétration une languette cassable (16) susceptible dêtre arrachée par une force extérieure est formée sur la paroi latérale extérieure de la rainure (121) de pénétration une extrémité du corps (30,
