Wild animals not provided with right tags (6)

I believe the answer is:
badges
'tags' is the definition.
(badging is a kind of tagging)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for badges that I've seen before include "Things worn to show membership or rank" , "Emblems, labels" , "Emblems of membership etc." , "Emblems to signify rank or membership" , "They are worn to show membership of an organisation" .)
