Consult daughter for bird food (4)
I believe the answer is:
seed
'bird food' is the definition.
(I've seen this in another clue)
'consult daughter' is the wordplay.
'consult' becomes 'see' (I've seen this in another clue).
'daughter' becomes 'd' (genealogical abbreviation).
'see'+'d'='SEED'
'for' acts as a link.
(Other definitions for seed that I've seen before include "What is sown" , "who is ranked highly" , "Germ; beginning" , "Pip - source - children" , "An outstanding player in a tournament" .)
