It is possible to ring new born birds when they are just a few days old.
The high rate of elasticity allows the ring to adjust to the leg of the bird as the bird grows.
Hence, the necessity to ring a bird several times, to prevent the ring from growing into the leg itself, it is significantly reduced.
The limited height of the rings makes it possible to combine several colours of rings, one above the other, greatly expanding the options for marking.
The EZ Elastic Ring Starter kit contains 20 rings(4 each of 5 different colours,red, green, yellow, purple blue) and also a special applicator.
