Fruit for the bird? (4)
I believe the answer is:
kiwi
I believe this clue is a double definition.
'fruit' is the first definition.
(kiwi is a kind of fruit)
'the bird?' is the second definition.
(kiwi is a kind of bird)
'for' is the link.
(Other definitions for kiwi that I've seen before include "New Zealander's bird" , "Symbol of New Zealand" , "Flightless NZ bird" , "Flightless New Zealand bird" , "Sacred Japanese peak" .)
