We recommend using stainless steel for all parrots larger than a Conure. They last longer and are better able to withstand large beaks but may be difficult to remove in case of an emergency.
These are only suggestions. They assume that you are using closed bands at 10 days old. If you use closed bands later you may want to go up a size. The inner diameter of open bands is reduced by about .5mm when closed. Please use your own discretion when ordering bands.
