in the event of an escape, where required, ETS birds must have their official Union ID Ring Number recorded

the same procedure would be accepted for non ETS after all that is the guarantee that these are the birds competing in that particular race and that is the important requirement.
in an escape a method should be adopted by the the organisers to ensure that escapees could not qualify for positions in that particular race.
