Game bird pig trader shot (9)
I believe the answer is:
partridge
'game bird' is the definition.
(partridge is a kind of game bird)
'pig trader shot' is the wordplay.
'shot' indicates anagramming the letters.
'pig'+'trader'='pigtrader'
'pigtrader' with letters rearranged gives 'PARTRIDGE'.
(Other definitions for partridge that I've seen before include "1st" , "Widespread bird" , "Flighty type" , "sort of quail" , "Peculiarly apt girder for the game bird" .)
