Recorded fragment about tailless bird (8)
I believe the answer is:
enrolled
'recorded' is the definition.
(to enrol is to record or register)
I don't understand how the rest of the clue works.
(Other definitions for enrolled that I've seen before include "Became a member" , "Registered,entered" , "being on board submarine?" , "The E in SEN" , "Admitted" .)
