Have another look at bird by a quarry (2-7)
I believe the answer is:
re-examine
'have another look' is the definition.
'bird by a quarry' is the wordplay.
'bird' becomes 'ree' (I've seen this in other clues).
'by' becomes 'x' (multiplication sign).
'quarry' becomes 'mine'.
'ree'+'x'+'a'+'mine'='RE-EXAMINE'
'at' acts as a link.
(Other definitions for re-examine that I've seen before include "Look at again" , "Study further" , "Investigate again" .)
