Most stores that have pigeon supplies will have the plastic bands that clip together. You can get them colour codes with paired numbers. Easy to see who's who from a distance. I have got some blue ones with my phone number. I've have also just got some plain pink ones for the ladies!For your birds........ since they are not racers,, the year is not sooooo critical. It is for your easy reference to when they were born
You keep track of them in your records. If someone is purchasing one from you,,, there would be no real issue of slightly off year.
For racers,,, I'm suspect there are less than sincere individuals that purchased their 2020 bands as early as possible, and try to slip them onto 2019 bird. Just to get a slight advantage. Racing clubs may control their sale of bands within club. Generic permanent bands from Outside of USA, can be ordered to say anything you want. They are good to include Phone # if desired, for easy contact of lost/found bird. They can print Year 2525, if you so desire. All those are Custom Made.
Most racing clubs do not allow birds (to fly, compete in races) with band other than racing club ones. Keeps Fanciers Honest by Default
WV,, just my thought/view and IDEA, about removable snap bands.
I used to place snaps onto other leg for EZ gender ID. Blue and Pink.
Never had one fall off BTW. I think that if there is some irritation caused by sharp edge on plastic ,,,, pigeon may have a tendency to try and remove. I always dulled/rounded that sharp edge with some FINE sandpaper. Another option to keep from falling off,, is a small drop of Krazy Glue into joint. I did stress SMALL, so glue does not overflow, and band becomes permanent with leg.
Plastic bands are easy to cut off if desired to remove. Permanent bands do pose a more of a challenge. But can be removed if you know what you are doing,,,,, without hurting pigeons leg.
