How to put a ring on your bird

Birds foot step 1 Birds foot step 2 Birds foot step 3

Depending on the species, birds are normally rung within the first 7 days before the bones in the foot have ‘set’.

  • Step 1 – Hold the chick in one hand and hold the leg with the fingers of the same hand holding the 3 forward toes together and the rear toe facing the opposite direction, then using your other hand, slip the ring over the front three toes.
  • Step 2 – Carry on slipping the ring across the ankle and over the back toe.
  • Step 3 – The back toe is then released and the ring will be on.
