Scrap pecked by bird (6)
I believe the answer is:
titbit
'scrap' is the definition.
(I've seen this before)
'pecked by bird' is the wordplay.
'pecked' becomes 'bit' (I've seen this in other clues).
'by' says to put letters next to each other.
'bird' becomes 'tit' (tit is a kind of bird).
'bit' after 'tit' is 'TITBIT'.
(Other definitions for titbit that I've seen before include "Choice piece, food or gossip" , "Small item of gossip" , "choice morsel" , "Delicacy" , "Pleasing scrap of gossip" .)
