If a wild banded bird is caught, I believe they are required to notify the national banding office who I believe is suppose to notify the bander. Since most states require a state permit (not sure if there is a national one required as well) to take falcons from the wild, I believe they (the state) has to be notified if a banded bird is taken as well. Question I guess is how good is the reporting system ...
A falconer in the UK once told me that falconry birds stay because they decide to, not because they have to. Not sure if that is just the way he approaches falconry but it does make a kind of sense ... but I'm not a falconer so its just anecdotal ...
