Sizing
-
Please note that the sizing is the internal diameter of the rings in millimeters. Use Ctrl+F to find your species.
-
Many of our customers are not used to ordering bands in metric sizes. This link to a pdf conversion chart may help.
-
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.
