A bird looked drunk (3-4)

I believe the answer is:

pie-eyed

'drunk' is the definition.
(I've seen this before)

'a bird looked' is the wordplay.
'a bird' becomes 'pie' (sort of bird).
'looked' becomes 'eyed' (eyeing is a kind of looking).
'pie'+'eyed'='PIE-EYED'

(Other definitions for pie-eyed that I've seen before include "Very drunk (colloq.)" , "Blotto" .)

I've seen this clue in the Sydney Morning Herald.
