Crowing
Those are some good leads. I’ll check out the Great Lakes rescue and try to get a friend to look on fb.Rescue pigeons can be hard to find if you live in a place with few pigeon fanciers or feral pigeons. There is one rescue, Great Lakes pigeon rescue, that ships birds all over the US. You may also want to check out shelters that accept birds, Craigslist, Facebook (there are groups dedicated to rehoming pet pigeons), or try to contact independent wildlife rehabbers, who sometimes have imprinted feral pigeons in need of homes (wildlife rehabilitation centers will usually euthanize or release such pigeons or only adopt them out to volunteers, though you could try them too).
