Ring size list

In the overview below you will find the recommended ring size for each water bird species..

The following points should be taken into account when ringing your wildfowl:

  • A closed ring is fitted to the growing bird at the point when it fits snugly over the foot so it does not fall off. For some wildfowl species, this is a very short window. Consult the birdguide for proper ring sizes.
  • It is important that the ring cannot slip up over the ankle (hock) joint.
