Scruff's parrot attached to pole (4)
I believe the answer is:
nape
'scruff's' is the definition.
('nape' can be a synonym of 'scruff')
'parrot attached to pole' is the wordplay.
'parrot' becomes 'ape' (I've seen this before).
'attached to' means one lot of letters go next to another.
'pole' becomes 'n' (**).
'ape' put after 'n' is 'NAPE'.
(Other definitions for nape that I've seen before include "Scruff of the neck" , "Back part of the neck" , "It's a pane in the neck" , "Girl personifying France" , "Here's a hairline" .)
