Bunch of feathers (5)
I believe the answer is:
plume
'bunch of feathers' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for plume that I've seen before include "Feather; wisp of e.g. smoke" , "Conspicuous feather of a bird" , "Smoke when rising" , "A fancy feather" , "Feather; column of smoke" .)
