Large-billed bird (7)
I believe the answer is:
pelican
'large-billed bird' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pelican that I've seen before include "Seabird with a large pouched bill" , "In place for large-billed bird" , "one with huge bill" , "Bird's" , "Large bird with enormous beak" .)
