Gaggle member (5)
I believe the answer is:
goose
'gaggle member' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for goose that I've seen before include "alternative to 7 [TURKEY]" , "Bird - tailor's iron" , "Bird; foolish person" , "Silly person" , "Large waterbird" .)
