To choose the appropriate band for a bird you must take into account the widest measure of the tarsus in the position where the band would be, (take into account the height of the band) and increase to that measure 15.75% up to 12 mm diameter and 10.00% for tarshes of greater diameter. The band should not be too loose or tight or fair. The tolerance is +/- 0.010 "(0.0254 cm). All sizes are estimated. The accuracy is determined by the mark on the band.
Following these recommendations, you will prevent the bird from being damaged by the band.

These bands are not for hummingbirds. Hummingbird banders are an elite group. Only about 150 people into the USA. They are only allowed to band after completing a rigorous training. Unlike other bird bands, those made for hummingbirds are cut and sized by the same banding. The banders are also expected to follow a code of ethics.
