Eat bird (7)
I believe the answer is:
swallow
This clue is a double definition.
'eat' is the first definition.
(I've seen this before)
'bird' is the second definition.
(swallow is a kind of bird)
(Other definitions for swallow that I've seen before include "Fall for; bird" , "See bird" , "Consume - bird!" , "Songbird" , "Migrating bird" .)
