Provided it survives the many hazards associated with racing, a single pigeon could compete from about six months of age and still be in competition at over ten years of age. Such feats are uncommon, however, and the average racing career rarely exceeds three years. Hazards can also come from weather conditions on the day of the race. Pigeons can become grounded and disoriented, and therefore not finish the race. In one instance in Madison, Wisconsin, in 1941, a family found a pigeon on their property. Since the bird was sporting an identifying leg band, the Wisconsin Conservation Commission was called, who identified the owner as a man from Green Bay.
