Boors grabbing hot birds (9)
I believe the answer is:
pheasants
'birds' is the definition.
(pheasant is a kind of bird)
'boors grabbing hot' is the wordplay.
'boors' becomes 'peasants' ('peasant' can be a synonym of 'boor').
'grabbing' means one lot of letters goes inside another.
'hot' becomes 'h'.
'peasants' enclosing 'h' is 'PHEASANTS'.
(Other definitions for pheasants that I've seen before include "Game birds with brightly coloured males" , "Birds at Athens spa" .)
