Stringfoot is the cause of much pain and suffering in pigeon flocks, and without treatment results in the loss of toes, feet or legs. Stringfoot occurs when pigeons get human generated detritus such as hair, string, fishing line or thread wrapped around their feet. The more they walk, the tighter it gets. Blood circulation eventually gets cut off and the toe/foot/leg dies. Removing stringfoot is not difficult and the pigeons appreciate it very much. In many cases, once the string is removed the pigeon can be released right away and the foot heals on its own.
