I second the above question, is there a two letter code going vertical on the band like AZ for Arizona
Also found the following info online:
Organizations such as the Society of Parrot Breeders and Exhibitors, the American Federation of Aviculture, the American and National Cockatiel Societies, etc., sell closed bands for their members that =generally= provide the following info:
Issuing organization initials/logo, Breeder’s unique ID code, year of hatch, state, and a number that identifies that particular bird.
A breeder who keeps good records can provide you the exact hatchdate, the parents, whatever genetic info they have, and other misc. info about that bird if given the band number. Most of these organizations keep contact records for the breeders, so if you call the AFA with a band number, they can put you in contact with the breeder.
Several commercial companies also sell closed bands that can have on them an ID code, the state, the year of hatch, and the bird’s number, or less or more than that. L&M keeps some records and may be able to put you in touch with a breeder who uses their bands, but a non-organizational band doesn’t tell you what company it was purchased from.
