Bird runs away from mole (3)
I believe the answer is:
pie
'bird' is the definition.
(sort of bird)
'runs away from mole' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'away from' suggests deleting specific letters.
'mole' becomes 'pier' (I've seen this in other clues).
'pier' with 'r' taken away is 'PIE'.
(Other definitions for pie that I've seen before include "welcome luxury" , "something with custard, say" , "Pastry-topped dish" , "Cooked food" , "Pastry product" .)
