I was asked this question earlier thought I would pass it on here.
Q: How would the authorities differentiate between a wild duckling that's been banded and a domestic ?
A: Wild mallard metal bands used to have an identification number on them. Then it was changed to "AVISE BIRD BAND WASH DC". Now they will either be inscribed with "CALL 1-800-327 BAND" or "WRITE BIRD BAND LAUREL MD 20708 USA" followed by an 8 or 9 digit number.
