Consume bird (7)
I believe the answer is:
swallow
This clue is a double definition.
'consume' is the first definition.
(swallowing is a kind of consuming)
'bird' is the second definition.
(swallow is a kind of bird)
(Other definitions for swallow that I've seen before include "Fall for; bird" , "Believe gullibly - bird" , "Songbird" , "Bird - gulp down" , "One doesn't make a summer, they say" .)
